Jack, just let me know they are launching a new frame with 61mm tire clearance. The 54cm frame is releasing this month; the other sizes are being released in June.
Cooked geometry
Can't wait to have more details !
I think several people on this forum including myself were looking for a chinese version of the Salsa Cutthroat and it seems like it could be it.
I checked the geometry and it's very close to the Salsa Cutthroat, the main difference is that the Salsa Cutthroat is suspension corrected.
I have been looking for a carbon bikepacking bike for challenging terrain and this would be a great fit.
Ok, this goes now on top of my list.
61mm clearance with 6mm space still both sides..
Geometry looks just spot on for me 😊
Wow! That's really cool👍

Is it a 54cm frame on the attached pdf?
Down the rabbit hole we go, 61mm has me excited. How many GRAVEL FRAMES clear a 61mm?
Now checking 2.4 MTB tires 🤩 Thunder Burt or Dubnital?!
Holy shit. Mondice adapting to the latest trends in a few weeks it seems, churning new frames like there's no tomorrow
was a 440 chainstay really necessary?
seat tube angle at 73.5 plus very short reach sounds like a missed opportunity

Good find! That's it! Just plugged in the geo and it's identical.
The rear is different.
New one has dropped seat stay ( open doesn't )
And the seat tube is different shape, on the lower end.
But good find still
I am thinking of replacing my giant revolt for this -lack of direct mount compatibility is annoying

I totally missed that haha. Good catch. I think dropped seat stays is better for gravel. Just my opinion. Definitely doesn't look as good though.

Are there some news on the time of year during which this frame will be available to buy?
Anybody have pictures of what this frame looks like?
Here is a 3D video of the 356.

Does anybody know, will this frame be sold on AliExpress?
Hi all,
on the first glance this frame seems to me like the one i´ve waited for. only the short wheelbase got me thinking.
I did a quick math and the following problem shows:
a: front-center: 611,5 mm
b: wheel radius: 755/2 = 377,5
c: crank length (short one): 165 mm
a-b-c=69 mm
Thats the room for your shoe form centre of the pedal to the front wheel. In my case i would need at least 95 mm not to get an overlap.
So my question: is this concerning? do i get it wrong? how much longer could a 56 frame be?

Hi! I have Carbonda CFR505 gravel bike in size M which have 597,8 mm front-center. I have 165 mm crank and 700x40 tires and I have overlap on veeeeeeery rare occasions and it don't bother me at all. Front-center distance is longer on this frame so i hope overlap will be less noticeble.

Yeah I think you're right. I checked my 2015 Diverge with which i never had problems and that's pretty short with 607 front center. Thanks for replying
Mondice top tube is 549mm, Open Wi.De 528mm. Seat tube angle both 73.5, Reach is identical with 374mm. How does this work? ???
Seems like Mondince can math correctly while Open relies on Gerard Vroomen engineering.

If you compare both frames at bikeinsights you get to see that they are more or less identical. The top tube length is imaginary. see both attachments

Unfortunately i cant help you here. i just have the numbers from the drawing from the first post of this thread and the numbers on the website of bikeinsights. so we have to wait for an official announcement from mondince.
but yes, from the numbers we have, the open wi.de 2.0 and the fm356 should handle different.

Jack from Mondince just told me that this frame would not be sold on AliExpress because this model was created by Mondince. So buying it directly from Mondince is the only option for this moment.
Jack just sent me the latest geo for this frame. See below.
A bit high and short it seems. Perhaps a consequence of the greater bb drop compared to my 21 Revolt size L.

It will be a bit tighter than Open wide 2.0 in size S
I am going to struggle to make it fit. I don't think I will get the bars low enough.
My '21 Revolt has;
Reach 391mm
Stack 601 mm
The FM356 in L has;
Reach 386
Stack 615
My Revolt has a 130mm -17 stem
This will be a bit high :( I can make the reach work as it is only 5mm.
Can't see an integrated bar coming in a-17°.
Im on the other side. I will be replacing my 2022 Revolt Advanced ML with a L FM356. On my Revolt I have to use a shorter stem (70mm) and have two spacers under the stem. It's almost like the FM356 is made for my fit. I just need to see a complete build in the flesh before I make my purchase
Yeah I like the tyre clearance, would just like to be able to achieve a reasonable saddle-bar drop.
I am 57yo and not super flexible or low. I see plenty struggling to get a decent bar height they are happy with.
I'm also fascinated by the tire clearance and waiting for the complete build. A bit surprised by the distance from bottom bracket to fork axle in size S. Compared it with my Carbonda CFR505 with 700x40 tires in size M. I will get huge overlap probably🤔
Jack from Mondince said that they will release this frameset at the end of June.

It would be cool if Mondince could enlarge distance from BB centre to fork axle in size S. Now it is 589 mm and there will be a huge overlap with 700x61 tires probably
Jack from Mondince said that molds of this frame are finished, so S size will have big toe overlap probably. The tire to pedal spindle distance with 29x2,4 tire in S size is 47 mm and in size M is 69,5 mm. So I guess that it is better to choose M size instead of S even if S size fits better.
Compared the new geometry chart with the old one and noticed that the fork became narrower in the upper part on the new geometry chart of FM356. There was a tire clearance of 15 mm in the upper part of the fork on the previous geometry chart. It seems that the fork tire clearance will be smaller in the new geometry chart. That is a pity. Bigger tire clearance is always better. Also I don't like the recess on the lower tube but I understand that it was done to increase tire clearance. I think that making a slacker angle of the fork would be better than making this recess because it would make the tire to pedal spindle distance bigger (which is good) and would also make bicycle more stable on descents (which is also good). I'm attaching old geometry chart (which is better) and new geometry chart (which is worser).

Bottom bracket height (from the ground to bb centre) will be 253 mm, so the distance from the pedal placed in 6 o'clock position to the ground will be 253-172,5=80,5 mm. I think it is ok for riding on tarmac.

I have 40cm at the hoods on my Revolt with 12.5° flare for the drops. I find it annoyingly wide after the roadie which is 38cm at the hoods. I would probably ride 38 at the hoods on a new gravello. I don't ride single track on gravel bikes and have never wanted wide bars.

This is rather strange. A few days ago Jack told me to "contact him in 20 days," which brings us to around July 6th.
My theory is that they're ironing out some kinks in the design or production. They might have held it back for a bit, considering that after the FM346 we got the FM366, and they usually tend to release these in numerical order.
Have you noticed how non-standard the water bottle layout is going to be? Since the main mount is positioned further forward, the downtube storage cover is completely separate from the bottle mount (which is a massive win). As a result, the two bottles will be spaced further apart than in a standard layout. I did a rough fit check, and two 800 ml Fidlocks should fit nicely.
Other than that, I'm super stoked. This frame is going to tick all the boxes for me, except for the toe overlap.

I got the info today that the frame is in testing now and it'll take ~20 days to finish that. Seems like they are also open to doing another 65mm rake fork afterwards, 50mm will be first though.
This sounds interesting, could you share some more details? I did some napkin math and toe overlap will be a killer in my case.
Will this be an optional/secondary fork for the upcoming FM 356, or is it a completely new project (e.g. FM 376?) with a bigger rake?

I sadly don't have more info. He just said that multiple people had asked since the open wi.de 2.0 also has a fork with more rake than 50mm. Will be for FM365 if it ever comes.
More agile steering is a bonus for me, i will probably buy both forks. I dont know if toe overlap would be an issue for my in a bigger sized frame, my feet arent particularly big.

I also asked Jack about the possibility to enlarge the tire to pedal distance, and he told me that they are thinking about making larger front to centre distance at least in size S.
Does anyone have info on the head tube size? I'm working on my parts list and got stuck on the headset. Should we expect the usual Mondince gravel standard—fully integrated 1-1/2" upper and lower (52mm ID / 56mm OD) like on the FM316, 326, 336, and 346—or is there something new?
My first choice would be Token A-Box TK1566P ZS56 / 28.6 l ZS56 / 40.

That was my plan, but I wanted to check here first. Sometimes someone already has the answer, which saves Jack from answering the same questions twice.
Going back to the information Jack shared about the headset setup:
"FM356 is standard FSA headset system. It is 52mm ID and 56mm OD."Secondly, regarding the BB-to-front-axle distance increase and the potentially higher rake fork:
"We have changed the front wheel distance to 600mm for size S. And we may do a bigger rake fork. But we need customer's advice for this.
We did not know whether the 65mm rake good for this bike frame."It looks like they went with the suggestions. I'm actually quite curious — how do they plan to gather customer feedback regarding that bigger rake fork? Has Mondince did somethig like that before?

As far as I understand they are listening to what potential buyers tell them. And that is very good! I told Jack several times that the current pedal to tire distance in size S is tooooo small and advised him to enlarge it. I think that I am not the only one who told Jack about it. Finally they decided to enlarge this distance to 600 mm. I think that we need to find out if 65 mm rake is good for us or not and tell Jack what we think about it.

Here is what AI is advising to tell Jack (see screenshots). Could somebody who is skilled in bike geometry comment on those advices?
Your line of thinking aligns perfectly with mine. Increasing the fork rake from 50 mm to 65 mm would drastically alter the bike's handling dynamics, completely deviating from the frame's intended design.
The reality is that toe overlap is mathematically inevitable for most size S road and gravel frames, especially when pushing into monster-gravel territory. To prove this, we have to analyze two distinct tire scenarios on a size S frame with a 600 mm front-center dimension (BB-to-axle, dimension "I") and a standard 170 mm crankset (like my Shimano GRX):
Case 1: NO-Clearance Setup (2.25" Tires)
Tire Diameter & Radius: A 2.25" tire has an approximate diameter of 740 mm, giving it a 370 mm radius.
Available Clearance: 600 mm (Front-Center) - 370 mm (Radius) - 170 mm (Crank) = 60 mm !
Result: This leaves exactly 60 mm of space from the pedal spindle (cleat center) to the tire.
Case 2: Full Monstrous Toe-overlap Setup (2.4" Tires)
Tire Diameter & Radius: A 2.4" tire bumps the diameter up to roughly 750 mm, or a 375 mm radius.
Available Clearance: 600 mm (Front-Center) - 375 mm (Radius) - 170 mm (Crank) = 55 mm
Result: This leaves only 55 mm of space from the pedal spindle to the tire.
Using my typical real-world setup: Shimano XC5 shoe (size EU42) paired with PD-M540 pedals—the distance from the cleat center to the tip of the shoe ranges between 88 mm and 108 mm, depending on cleat adjustment.Even in the most optimistic, hypothetical scenario—running the smaller 2.25" tire and slamming the cleat all the way forward (which is not recommended for proper bike fit)—we are still short by 28 mm (60 mm - 88 mm).To completely eliminate this 28 mm deficit by stretching the frame, you would have to increase the reach so much that the front-center (dimension "P") would enter L/XL sizing territory, rendering the frame entirely unrideable for a size S rider.
In my specific case, I run my cleats slammed all the way back, meaning I need 108 mm of clearance from the spindle to the shoe tip. The math leaves no room for compromise:
With 2.25" tires: I will experience a massive 48 mm toe overlap (60 mm - 108 mm). :(
With 2.4" tires: The overlap increases to 53 mm (55 mm - 108 mm).
There is simply no escaping the physics here. While eliminating toe overlap is a great goal on paper, forcing it onto a size S frame designed for high-volume tires is mathematically impossible without fundamentally ruining the bike's proportions and handling. In this size category, massive toe overlap is a reality we probably just have to accept.
EDIT to prevent double posting.
OK, I had a look at some gravels for that bb-to-axle distance.
Grizl CF XS (pre 2024) - 595 mm
Grizl CF XS - 625 mm
Grail CF XS - 604 mm
Topstone 47 - 601 mm
Topstone 51 - 605 mm
Checkpoint 54 - 606 mm
Diverge 54 - 615 mm
Revolut S - 607 mm
Addict s/52 - 608 mm
Locally popular gravel AL S - 609 mm
Grizl is well known to be designed long and to be used with short stem.
I usually don't write much, but i thought i might as well give my opinion, if it could influence the way this bike turns out. In my opinion toe overlap is a way smaller problem than people make it to be. Given how far you need to turn the handlebars for the wheel to be close to you foot, for it to actually hit while turning and pedaling the speed needs to be really low. I have a bit of toe overlap on my road bike, and im a totally sure, whenever i feel the need to pedal through a turn, (i want to go fast) the pace is way to high for me to be turning my handlebars enough for it to be a problem. So what im trying to say is, i would much rather have the steering of a 50mm fork than the clearance of a 65 mm fork, even though im in between sizes and might end up with a size small.
Might just be my lukewarm take, but if anyone is planning on summarizing this thread to Jack, i thought it would be worth to mention, since i am pretty interested in the frame.
Just compared the geometry of Mondince fm356 in size S with 700x61 tires and Spcycle SP028 in size S with 700x61 tires. Spcycle have a bit longer reach that gives the tire to pedal spindle distance of 70 mm. So probably enlarging the reach a bit or slackening the headtube angle could be a good solution to avoid toe overlap if it is still possible to change the geometry of the frame.

Maybe a 55mm fork would be the perfect middle ground.

Just asked Jack about offset and he wrote me that front to centre distance in size S is enlarged to 600 mm and the fork offset is left to be 50 mm. So probably some changes were added to frame geometry.
TanTan have just posted "ISO" style testing videos on their Instagram for their new 61mm clearance frame, apparently called "GR356". This looks to be the same as this Mondince which would make sense given how it worked when the FM346 came out. They haven't posted any geometry yet so it will be interesting to see what the new, longer front centre, geometry is like.

Comes from the same factory, so will be the same frame (was confirmed by mondince). Also got some bad and good news from them.
Bad news - they dropped the riser bar project, apparently what ever they designed wasn't up to standards to they won't sell for now.
Good news - mass production will start in approx. 4 days, it's 625 usd per set incl. frame, fork, seatpost, axles headset, frame bag. default color black matte or ud matte.
As others already mentioned only size s was adjusted, rest stays the same.

Probably that mean that some day this frameset will be presented on AliExpress, because most ( if not all) TanTan frames are presented on AliExpress.
Update: Mondince and TanTan wrote that they will not going to sell it on AliExpress☹️
Mondince made update of S size. They made top tube 1 cm longer. Now the tire to pedal distance is 56 mm instead of 47 mm and that is still not enough to avoid toe overlap☹️ I asked them to slacken headtube and enlarge front centre distance more but Jack wrote that they will not make frame longer. So probably for me it is better to buy M frame instead of S unfortunately☹️
Tan Tan bicycle factory wrote two days ago in their Instagram account that frame will be available in 25 days.
Does Jack already take orders for the frameset or we need to wait?

I'm waiting until somebody build bike on this frame and give us measurements of tire clearance with 29x2,4 tires🙂
Same here. I also want to see the colours first.
I wish they could build the sizes, fit them with a groupset, and show the colours so that we can see how the bike will look like fully built
I'm planning on a custom 2 colors and white letters paintwork.
I'm confused, is the FM356 not on the mondince homepage yet? I just see the FM346

Jack wrote that FM356 frameset would appear on Mondince web site in 7 days and photos of the frameset would be made in 2 days.

Exactly.
I think toe overlap is a problem that does not actually exists.
If you are going very slow and turning a lot (think u turn) then this might be a case. Otherwise you won't touch your wheel. And even if you do, just stop pedaling. It's not a fixed gear.
My prefers road frame has a lot of overlap. I ride it still and I never ever had an issue with this.
I do love how it turns by itself which only happens because it has short wheelbase combined with steep head tube.

To each their own, but I'd be surprised if even 5% of the people on this forum are actually looking for a really low-stack bike. I'm not even sure what a low stack is all that beneficial for anymore. It used to be considered the more aero option, but that doesn't seem to be the case these days. Just look at modern TT bikes. A lot of them have 100+ mm of spacers under the aero bars because that's where riders are finding the best mix of comfort, power, and aerodynamics. Looking through the FM336 build thread, it also seems like a lot of people are running quite a few spacers under the stem anyway. To me, that says many riders are trying to get to a taller front end regardless. This frame clears 61 mm tires, which is 2.4 inches. This bike was designed for adventure riding and long days in the saddle, not an ultra-aggressive race position. Personally, I like that they gave it a taller stack. It lets more people get the fit they want without stacking a bunch of spacers under the stem, and I think it ends up looking cleaner too. I'd actually love to see more bikes go in this direction because I think they match how most people really ride.

Overlap can be an issue in traffic jams and on bad flat forest roads with roots, water puddles, grass and so on where you need to chose and change direction of movement on low speed very often.

Low stack feels more responsible, wrong bike fit set me to a ridiculous stack height, lowering it a couple of cm and turning around the stem made the bike feel much more nimble.
For the kind of bike this mondince is the stack height seems adequate, you can always run it with no spacers and negative stem angle.

Well we clearly have different preferences and that is fine. I expect you percentages are out, given the popularity of the SP028 thread with its much lower stack height.
I would like a gravelo with a larger tyre clearance than my current goer. I use it for dirt roads, fire trails and rail trails.
I would like it to approximate the position of my roadie as a result.
The current gravelo has a lower stack height but still needed a -17° stem to get there.
Here it is with an old roadie.(https://ibb.co/1Y4b1WWM)
https://ibb.co/1Y4b1WWM
Makes total sense, and like you said, to each their own. I'm hoping one of these Chinese companies eventually gets organized and creates a catalog that's clearly designed around the different types of riders. For example, have a low-stack, long-reach "aggressive" frame and market it as exactly that, then offer a high-stack "all-day ride/bikepacking" frame, and maybe a third option positioned as an "endurance" bike for long weekend rides. Right now, the nuanced geometry differences and the constant release of multiple, very similar frames just make the buying process more confusing than it needs to be, at least in my opinion.....BTW nice stable.....
Just got sent these two videos, color is chameleon green.
Here's a screenshot from the video:

Few more pics of frameset from Jack. The size is M. Black parts on the fork are rubber inserts. Photos of tire clearance with ruler are needed.
Just ordered, apparently they'll have a batch ready next friday. Seems like they also have no issues leaving out some of the mounting points / rivets if asked. I for example don't really need the front rivet on the fork (also looks kinda ugly imho. ;D)

Well, I'd prefer through-hole at the middle between strap holes, like on open wide 2.0. It could be easy converted to 3 rivets with 3d-printed insert.

Thanks for the link! It would be supercool if you could build complete bike with 29x2,4 tires and share photos of it🙂
Tantan factory just posted pics of this frameset with handlebar in their instagram account:
https://www.instagram.com/p/DapPAg2jlzt/?igsh=MWszangzeHQyMGFoNg==
Also there is a weight of frame without fork on the photo. It is 1307 gr. I think it is size M.
I have to say, those "reviews" are a blight nowadays. Sadly, they are a bit off-putting – true.
I wanted to ask you about the fork. Do we have two options to pick from – with and without those black inserts? Also, can you tell me what those holes, covered by inserts, are actually for? They look different from the ones on the Open WIDE 2 fork.
I am ordering one too (Size S) and I wonder what the timeline looks like. Most of the parts are already at my place. We will see how it comes out. Progress will be uploaded for your viewing pleasure!
EDIT: One change - there suposed to be protectors like for 346 and they seem to be missing. :-\

Maybe they are just off from that frame ?

I asked Jack the same question about rubber inserts and that is what he answered:
" It is a rubber. When customer want to intall bag there. the can wrap the bag"
I think those holes in the fork work the same way as on Open Wide 2.0
Has anyone actually recieved their FM356 frame? Interested in knowing the actual tire clearance before I pull the trigger myself. I'm in no rush as this will be a winter project for me.
I wanted to buy one, but Jack told me that they will still need about 20 days to produce size L.

Sort reach and high stack. It appears to be a bike packing/touring bike. Mount points all over it. Not a gravel racer.
As they list it;
https://www.mondincecycle.com/product/fm356-61mm-max-tire-clearance-carbon-bikepacking-gravel-frame
I think mondice says the 356 is a adventure/bikepacking frame. I would even classify the 346 as a relaxed frame .
I've just got tire and crank clearance photos from TanTan factory account on Instagram.
Asked Tantan and Mondince about the price for frameset, custom paint and shipping.
Answer from TanTan:
699usd/set . include paint
frame+fork+seatpost+headset+spacers+handlebar
EMS shipping fee 79usd
778 usd total
Answer from Mondince:
The shipping cost is USD280 by fast shipping, slow shipping is usd120 with 50 days.
The cost is USD625 per set, and USD100 for custom painting.
Incuding frame, fork, seatpost, axles, headset, bag, painting cost.
1005 usd or 845 usd total
Offer from TanTan is more interesting from my point of view.
I've been comparing the specs again, and the only difference I can see is the weight (beside really small geo differences according to the tables). The Mondince frame is listed at ~1100g, while the TanTan comes in at ~1300g. That's a pretty big gap for what seems to be the same mold.
Which fork version would you pick (1 - regular; 2 - luggage)? Are there compatible luggage packs available?

I'd like to try the #2 luggage fork but I don't think that I will really need it😁
I think Mondince weight is raw ( without paint )
And Tan Tan is painted.
So with tan tan you get handlebars also..
That's interesting

It's a candy red into raw ud carbon fade. They can do any color with the candy effect. I was stuck between red / blue and green, but in the end my current helmet matched the red -> black fade so that's what I went with.

Thanks for the photos, looking forward to the complete build / if the sun is out. The transparent red looks kind of similar to the Angle Cycle Gamma (the gravel bike that is shown in some zara stores) which looks really cool in person and has some silver logos under the red clearcoat. I will try to get such a paintjob from mondice or light cycling with the new FM376.

Yup looks really nice in person as well and it's actually way more red when the sun hits it. Sadly mondince didn't include the rubber downtube protection, apparently not ready yet. They'll ship it out once it's done.
The balugoe stem + spacers / topcap also somewhat fit with a little gap. Will probably swap to yishun integrated cockpit anyway once I've found a nice fit.

Opened / closed it a few times, doesn't seem like there are any issues. Fits snug. They also only painted the outside.
I also received my frame today. I will try to post proper photos after building the bike. The frame and everything else looks great - I got frame (M), both types of fork, seatpost and integrated handlebar they supply with their FM126 road frame.
This is a second frame I received from Mondince, it´s actually a replacement/warranty frame. I initially ordered and got an FM336 frame - but it was from the batch of frames with glue left inside and it was impossible to route the shifter cable through chainstays. When I spoke about this issue with Jack, he was really straightforward with it - either I manage to clear up the glue and they will send me back around 150€ as reimbursement or a new frame, if it won´t work. I managed to clear up the brake line glue, but the drive side was narrower without proper access - and it was out of my budget to get an wireless groupset, so Jack agreed to send me a new frame.
FM336 order was in march, i got it in may and by the time this all came to be, the new frames 346 a 356 were supposed to be shipping in about two weeks +-.
So I spoke to Jack, whether it would be possible to send me another frame, which he was okay with - thankfully, I just needed to pay for the fork and difference between the frame prices, since FM356 was a bit more expensive. That was at the end of may, and supposedly the molds were supposed to be ready around middle of june. Well it took quite a bit longer, but finally it´s here.
All in all, except the provided time lines, everything else was really good. Jack usually replied within an hour and answered all my questions. Reading a bit on this forum about different experiences with manufacturers, I think from the budget brands Mondince has the best customer service and actually replies and tries to help you solve if any problems arise after they sell you their frame.
Also both frames had properly faced brake mounts and BBs, also the headset cups are nicely reamed and faced. The magnetic cover on fm336 opens and snaps in place much easier, but the mechanic lock on fm356 feels more secure - so it´s a toss.
I included the handlebar drawings, the weight is 350g for 380/90. It looks like fsa acr style headset, also in the drawing the drop dimension is measured wrong, it actually is 110 instead of 120, which i prefer.
Measured dimension between chainstays is 73mm - so 61mm tyre with 6mm space on both sides is according to spec. As for the fork the dimension is 73mm also.
Lovely colours for both bikes. Waiting for mine...
I managed to build it up today,
still not even ride ready, but at least it looks finished. Don´t mind the tyres, i am waiting for a bit bigger thunderos, but for now it´s what I have on hand.
The build went pretty okay, I managed to build it without cable routing tool. It was a bit pain around few places, mainly handlebars, but i managed.
BB is not alu shell, both sides are bonded independently. The water bottle on screws on the storage cover are unusable for bottle holder if you also have a holder on seat tube. The storage space is extremely small and with the cables in foam running on bottom, there´s really not a lot of room. I will have to source bag from thinner fabric so hopefully, I will fit there at least multitool, plug kit, pump and tyre levers.
The wuzei chainring is 44t with 4.2 offset screwed on road dub cranks. Sadly my 40t rival chainring does not fit - too big offset on road cranks, so i will need to find something different because the wuzei one is extremely noisy. The chainring has around 2mm space around chainstay.
The metallic pink with the black fork go well together. Internal routing for the bars was the most frustrating part of my recent build as well. Looks like you could use the second set of mounting screws further up from the storage for a second cage along with the seat tube.

Not being able to use both bottle holders is concerning. Would it be possible to mount the one on the cover further up if it had slots instead of holes, or would that interfere with the cover's handle?

You can get cage extenders to move the bottle up. I also wonder if this is specific to certain sizes. Mine is a L and when it arrives, I will let everyone know whether I can fit a bottle on the hatch + seat tube

Yes, that's what I was getting at. But if the cage blocked the handle, that would be bad too. I also ordered a size L. Hopefully this won't be an issue at that size.
With the extender and bottle cage maxed out, it just barely fits - but you won´t be able to open the storage door without removing seattube bottle as it need to tilt up first.

Sorry to see it, but I pointed this out few pages ago. I belive it will be similar in all sizes. :-\ This is a layout to accomodate "under-top-tube" bags, where you have just one bottle.
I would like to order the frame in glossy black. They have plenty of options like UD raw, normal black and pearl black. What is most recommended and the low-maintenance (cleaning wise) choice?
The bottle screw positions seems to be a major design flaw. Is this only the case with size M?

Hi! Did you have the opportunity to try 29x2,4 tires? Did you make some more rides? How it rides, how it handles, how it feels?)

I'll snap some better photos once the sun is out.
Hi! Did you complete the build?
Just did a ~4km test ride to bed in brakes etc. Rides great from first impression. Still have a bit of a chimney above the stem, due to playing around with the stack. Will probably leave the spacers how they are right now (20mm including headset topcap) and shorten the steerer. Running 2.4" Pirelli Scorpion XC RH atm. but I think I'll go down to 2.25" thunder burts for my normal riding.
The candy red looks fantastic in the light. Might have to do something similar with my next build.

I don't have a caliper at the moment. Measuring with an allen key, it's ~6mm each side on chainstay and seatstays the 8mm fits. Fork the 8mm also fits, plenty with the tire measuring ~61mm on 32mm inner width rims.

We just don't have the terrain here, mostly flat / no elevation hard pack gravel with little bits of single trail. The scorpions have quite low rolling resistance though, so I'll see how I get on with them first.

It would be cool if you could extract rubber inserts for luggage from the fork and take a pictures of fork without them to be able to see how they are made. I asked Mondince about it but they didn't make such pics.

176cm / 81cm inseam.
Is this frame capable to carry two water bottle cages with medium to large sized bidons?
I like the tyre clearance!
It is very high stack.
This look great. What do you guys think, could I also go for an L with 177/83? My current Giant Revolt in M has the saddle all the way up and I'm using a 35 degree stem, from the geo charts an L frame would come out to the exact measurement of my current bike.
Has anyone seen a hole where you could route a dynamo cable?

What is the length of your cranks? Do you have tire overlap?
My Size L frame arrived today. Overall, the finish and build quality look very clean out of the box.
Actual Weights (without thru-axles)
- Frame (Size L): 1,400g
- Fork: 506g
- Seatpost: 250g (definitely on the heavier side)
Initial Observations
- Bottle clearance: Can confirm the bottle clearance issue is still present in Size L. If you mount a bottle cage directly to the downtube storage compartment door, you will need an extender/drop bracket to fit a second bottle comfortably.
- Fork slots: I ordered the fork without utility slots, but the outlines/ghosting of the slots are still visible under the finish. It does not bother me much, but worth noting for anyone expecting a completely smooth profile.
- I dry-fit a Ritchey Switch headset I had lying around, but ended up with an awkward gap at the head tube.
For those who have already built up this frame: which headset model/stem setup did you use, and did you manage to get a flush fit without a visible gap?
Will post detailed photos once the full build is underway.
I used headset bearing and cover provided by Mondince with the frame and handlebar. Plastic parts are FSA ACR copy from the looks of it. The top bearing is 8mm tall and the gap is like 0,5mm or smaller.
Has anyone tested actual tire widths and frame spacing? the 57mm version has 6mm on each side of the tire if it's a 57. Is that the same for this version?

No, contacting them wouldn't really help me, it isn't something you could resolve without moving the cover higher up on the downtube. Why they didn't place it there in the first place beats me.
Crank & Power Meter Clearance Note:For anyone wondering whether a road crank with a spider power meter (like the Magene PES P515 or GEOID PM500) fits: technically it clears, but the chainstay clearance is virtually zero. It's too tight to run safely, so unfortunately I'll have to swap to a different crankset.

Plz, let us know - do you have the problem with tire overlap with 29x2,4 tires and cranks of what length do you use?
My "Morra" ( Italy means Moomin Groke 😁, but I'm from Finland)
30mm internal wide rims , 60mm speed Pro tyres .
And because of autumn I have mud guards..
With those a little toe overlap, but without there is no.
Boring but good basic 1 x 11 GRX build for me..
This is going to be my adventure and bike packing bicycle..
Oh size M and matte raw carbon color.
honestly, the high stack in combination with the high slope does not look good
High slope ?
Sorry my English, don't understand.
High aero bars are for comfort ( and they are these days a bit higher )
Stem angle is only -6 degree.. not very high ?
I went for France style driving position ( same saddle height and bar )
This was not supposed to be " beautiful" ... It is going to be comfort and practical.
😁
I believe they should have sloped the top tube less ("more horizontal") to make it aesthetically more pleasing. This would work well with the long head tube and this would have also mitigated the problem with two frame bottles colliding with each other.
@Jarkko2410
Which mud guards are those?
Could a front mud guard fit between tyre and fork?
Your bicycle looks really excellent. Versatile, fast and comfortable! Almost exactly what I picture my build to look like!!

I think that is because Jarkko2410 made this photo with wide lens (1x) of his phone and proportions of the bike became distorted a bit. If he photographed it with zoom lens of his phone the bike would look better. Have a look at the photo of this bike in the same M size by xcelrec photographed with zoom lens probably

I think there is enough space for normal mudguard.. yes.
Here is what I used :
It's designed for 52mm tyre, but it's good enough for my speed Pro tyres.
I've never installed a dub crank before, so I don't know if I'm doing something wrong, but it looks like my BB shells aren't square. It's binding like crazy, even though I haven't even adjusted the preload yet.

Depends a little, shouldn't be that much drag tho. My axle also went in noticeably harder than my old bike which also had used dub wide cranks. If you are using SRAMs BB, they have small blue o-rings which usually add a little drag, check if they are still seated and grease them. You could even try installing just the non drive side with axle, but without the o-rings in the shell to see how it turns. If it's still really draggy check the bearings and if they also run smooth it's not unlikely the bb shells / threads aren't aligned.

I think there was something wrong with the BB adapter sleeve on the BB I used. When I measured it with callipers, it was quite a lot less than 28.99 mm, which explains the excessive binding. I tried using the original SRAM bearing and it's much better now. It's not quite perfect, but I think this is alright?

Yeah looks good. Should be even better after they are broken in a bit. Sram bbs are notoriously draggy when new and mine don't spin any better tbh. :D
Been following this thread while building my FM356, so here's mine. It's my
dedicated rough-gravel rig (fast-road duties live on another
bike), so the priorities were tyre clearance and high stack.
Spec
- Frame: Mondince FM356, size L. Mondince headset with their integrated
cable routing - the included C-ring is actually really good.
- Drivetrain: SRAM 1x13 mix - Force crank (165 mm) + Force 10-46 cassette,
Rival XPLR AXS derailleur, Rival levers/brakes.
- Chainring: 38T Alugear oval
- Wheels: Elite Wheels Gravel Aero+ (32 mm internal)
- Tyres: Specialized Pathfinder Pro 2.2, tubeless - a true 56 mm WAM on the
32 mm rims
- Cockpit: Deda 90 mm alloy stem + PRO 44 cm alloy ergo bar (two-piece for now
while I dial in the fit)
- Rotors: IIIPro rotors 180/180 - brake performance is not diffrent to 160mm rotors
- Seatpost: Mondince 20 mm offset
- Weight: 9.2 kg ready to ride (pedals + bottle cages)
A few build notes
- Up top the clearance is great - 56 mm tyres with 10mm room to frame. But chainring
clearance to the chainstay is tight: I went 38T partly for the gearing, but
anything over ~44T would want less than the usual ~6.5 mm offset to clear,
especially with the SRAM DUB XPLR Wide crank. Worth checking before going big
up front.
- Minor gripe: there are almost too many mounts - three bolts around the fork
crown just for a mudguard feels like overkill.
Ride impressions: versatile and comfortable - the big Pathfinders float over
loose gravel without feeling draggy on tarmac, and the 1x13 range covers
everything. But it feels kinda slow: Been on the Tideace GV201 before, and this was quicker.
(Attatched photo with Schwalbe G-One R Pro 50mm, 53mm WAM)
I've also finally completed my build. Here are the specs:
- Frame: Size L
- Cranks: SRAM Force with spider PM (160mm), 36T Alugear thread-mount chainring
- Shifters/brakes/RD: Shimano Ultegra Di2, with a Deore Di2 RD-M6250-GS rear derailleur
- Cassette: Shimano XT CS-M8200, 9-45T
- Wheels: Elite Wheels Gravel Aero+
- Tires: Specialized Pathfinder 2.2 (they measure up to 58mm on these rims)
- Stem: Deda Superzero. The included compression ring was a bit too thick and left too much of a gap, but with the optional HDRS-COMPR-ME it fit perfectly.
- Handlebars: Deda Superzero Gravel Alloy
- Rotors: Campagnolo 03 AFS, 160mm
Just did my first test ride. The bike felt very comfortable, and I really liked the new Pathfinders.
One strange thing: I had to set the rear derailleur indexing to -18 (the maximum) for it to shift properly. Not sure what's going on. Could it be an issue with the wheels/freehub and how the cassette sits? Has anyone seen this with these wheels or a similar setup?

There is road microspline and mtb microspline, freehub is the same in both versions but the endcap isnt, road one is a bit longer to account for narrower hub. I had to use an extra spacer ring on my wheeltop rd because i couldnt find 9mm QR endcap for road microspline.

Huh, I didn't know that. TIL. Could you explain the spacer ring a little more? Where did you put it, and what thickness was it?

- Wheels: Elite Wheels Gravel Aero+ (32 mm internal)
- Tyres: Specialized Pathfinder Pro 2.2, tubeless - a true 56 mm WAM on the
32 mm rims
- Cockpit: Deda 90 mm alloy stem + PRO 44 cm alloy ergo bar (two-piece for now
while I dial in the fit)
- Rotors: IIIPro rotors 180/180 - brake performance is not diffrent to 160mm rotors
- Seatpost: Mondince 20 mm offset
- Weight: 9.2 kg ready to ride (pedals + bottle cages)
A few build notes
- Up top the clearance is great - 56 mm tyres with 10mm room to frame. But chainring
clearance to the chainstay is tight: I went 38T partly for the gearing, but
anything over ~44T would want less than the usual ~6.5 mm offset to clear,
especially with the SRAM DUB XPLR Wide crank. Worth checking before going big
up front.
- Minor gripe: there are almost too many mounts - three bolts around the fork
crown just for a mudguard feels like overkill.
Ride impressions: versatile and comfortable - the big Pathfinders float over
loose gravel without feeling draggy on tarmac, and the 1x13 range covers
everything. But it feels kinda slow: Been on the Tideace GV201 before, and this was quicker.

How did you make the direct mount derailleur fit? My bike shop can't fit one, they said the width should be 12mm and my frame is 10.8mm. Jack is saying the bike isn't meant to take a direct mount derailleur and I need to use a hanger

as per TanTan GR356 specs younshould be able to. Dropout is UDH:

My FM356 is way out of tolerance and the direct mount transmission wouldn't fit. I've asked Jack to replace the frame but he's trying to fob me off with a small £100 refund. Alternative is to charge back with my bank but I don't want to do this yet.

3D printing a resin+fibres part with their help, and then receive the refund according tonthis solution, should be an intermediate optiom

Were you able to finally fit the transmission?
I've ordered this frame to TanTan in Sep 22th, waiting for it to be shipped. Will post here the process! :)
Got my Mondince frame last week, now it's waiting for test ride (and one bearing from Jack). I have S size, toe overlap... Hmmm, took couple rides around the block and in tight slow turns flipflops hit front tyre. Hopefully with proper shoes it's better. At 170cm short cannot get much bigger frame anyway.
I'm 170cm and driving size M
80mm stem
Feels good. French style build for long distance riding ( saddle / handlebar same height )
Quote from: Er7ik on October 02, 2026, 05:29:03 AMBeen following this thread while building my FM356, so here's mine. It's my
dedicated rough-gravel rig (fast-road duties live on another
bike), so the priorities were tyre clearance and high stack.
Spec
- Frame: Mondince FM356, size L. Mondince headset with their integrated
cable routing - the included C-ring is actually really good.
- Drivetrain: SRAM 1x13 mix - Force crank (165 mm) + Force 10-46 cassette,

Color looks familiar 😄. Looking good with the silver chainring.
I was wondering if anyone who has gotten on has any feedback on the BB height when running narrower tyres around 40MM. I know it is designed for wider, but thinking around running two sets of tyres, one for raod and one set for Gravel
I've just received my Tantan GR356 size M. Painted UD Glossy.
I'm willing to use it at gravel events and some ultra. I am a little bit concerned about bottle mounts position.
Apparent build quality is good enough. T-type is allowed since the thickness is 12.5mm.
QC issues: front axle thread is out of spec, it does not pass through the wheel.
