I was speaking with Mondince (Jack) and he said they are about to start production on a new gravel frame with 57mm tire clearance and he shared the geometry which I’ll attach. It looks very promising for what I am looking for. First mold will be 54cm.
-
54 reach is 376?
Did they miss a digit there?
-
For a moment I was regretting ordering FM336, but looking at the geo, it just doesn´t make sense for 57mm tires.
The frameset looked vaguely familiar. It´s not perfect copy but definitely inspired by Cannondale SuperX, which also BXT 055 is based on.
-
Stack and reach fit together for a relatively short frame. I'm more surprised about the BB drop of 69mm only. That's less drop than the average road racing frame and pretty much CX like - very gravel unlike.

Nice catch. Geometry is very similar to the 54cm SuperX. Wondering why you don’t think it makes sense for larger tires?
-
A bit steeper seat tube 74 - 74.5 deg. Shorter chainstay (425mm max), 80mm BB-drop and then possibly a bit longer front center to still keep same top tube length. And possibly a few degrees steeper head tube. Then it would be perfect.
Shorter chainstay and BB-drop is the only things i think is needed, the other ones would be just a bonus 😎
-
Long chainstay, short reach, small bb drop... This geo sucks
-
Looks great! Sign me up. I will be able to make it work fine 8)

Short chainstay and 57mm tires don't fit with road standard bottom brackets. You'd need to use MTB crank/axle with it's wider chain line.
-
I have to correct what I wrote. Fara G4 has 425mm rear center, 80 mm bb drop and tire clearance of 57mm/2.2"
So so wide tires are doable with a relatively short chain stay. 1x only, OC. At least I haven't read that the G4 requires Dub Wide axle.
-
Long chainstay, short reach, small bb drop... This geo sucks
Didn't see that high bottom bracket, that is surely something they need to fix.. BB drop should be better of at least around 78-80mm on this frame.
I would like to see geometry more like this attached drawing instead.
-
I like this one..
For me the 425--->435mm 1cm difference doesn't affect my riding.
Stack and reach figures nice too .
And 57mm clearance meaning I could fit the 2.35 speed pros there.
I will order this as soon as it is possible.
-
Also, when comparing other 54 frame ( 382 reach ) I don't think there is any mistake
This one has 376.. so only 6mm difference .
Oh I was comparing the newest frame they have at the moment fm336

382 is small for a 54 frame - I'd expect above 385, not 376.
The stack is already huge - and you can't expect someone of average height e.g. 175-180cm to use a 140mm stem. Sizing up will make it uncomfortable due to the reduced seatpost. Frames should be coming forwards and longer and seatposts more steep to allow people to ride faster.

Well... an SL8 (Road racing frame ;)) size 54 has 384mm. A gravel should be shorter... So i think 376 is just fine.
But yes, BB drop schould be bigger when mounting fat tires
-
The two strange things about this design is more the high bottom bracket and very tall seat tube.. 524mm seat tube is aero race bike territory.
The other things is more a like or dislike thing i guess.
But i think more modern geometry usually have steeper seat tube angle, and a bit longer front center. If you add 0.75deg seat tube angle and longer the front 10-15mm to compensate, then you achive longer reach without longer top tube, and at the same time makes (a bit) more room for shortening the chainstays a bit.
-
IMHO long seat tube and therefore less sloped top tube makes for a gravel frame that aim for bikepacking.
Check the Yoeleo Altera G21, they took the same approach. More space for frame bags, especially for the smaller sizes.
And you see from CX bikes that sloping isn't necessary even for very technical riding.
But Yeoleo went from 72mm bb drop to 79mm bb drop when evolving from the G21 to the Altera G21.
-
I have a 2021 Giant Revolt adv2. This would replace it.
I have a size L, so bigger. I had a look at the geometry chart for it in a size M and compared. The Mondince has a lower stack, a touch less reach, same bb drop and similar chainstay length. The lower stack is the biggest change. The reach is shorter due to steeper seat angle.
I have a -17 stem on my Revolt due to the high stack.
The bb height I like. I do not want lower on a gravel bike.
25k km on the Revolt. This will be a good replacement. I want the tyre clearance.
-

personal thing i do not like is the seattube length combined with 57mm tires and BB drop will be quite tall standover height, i would appreciete it being at least 15-20mm lower.
The bigger issue is toe overlap, it´s nice that the fork will fit bigger tires, but it´s on the limit of acceptable for me. Compared to my more road oriented seaboard with 40mm, it´s the same clearance. It´s not terrible but i regularly catch my toe on the wheel when riding singletrack or anything slower and more technical. BB height is just another thing copied and not thought about, 70mm drop works fine with 40mm tires, but 57mm? that´s just weird, moving the centre of gravity up, not that it won´t work, it just seems not thought through to me
-
You guys know way more than I do about all this geometry. It’s like a different language. 1 degree here, 3 mm here, 5cm here. Idk about all that.
I don’t claim to be a smart man but I do know that I’ve ridden a Cannondale SuperX and it rode well. Only reason I didn’t pull the trigger was tire clearance. That was last year before I started diving down the Chinese market rabbit hole.
This geo is essentially the same from what I can see, but with larger tire clearance.
So from my perspective, looks good! Hahaha
-
I went from 67 bb drop to 79 on the Altera and there's a big difference when cornering. On the 67 (Ican X-gravel) I often had to make small adjustments when in tight turns and it felt like I had to fall into the turn but the Yoeleo feels like it's on rails and gives more confidence to go fast. I'll never go back to 70ish bb drop. But I have a high saddle height and 50mm tires so I guess it amplifies the effect.
-

That's interesting, I wasn't aware the older models of the Revolt had such little BB drop. The new model has 81mm.
I'm also used to high BB, riding a Cube Cross Race as garvel bike and racing CX on a Ridely X-Night, and I feel conforable with that, but that's still not the BB drop what I expect from a gravel frame. Somehow ;-)
-
A gravel should be shorter
But yes, BB drop schould be bigger when mounting fat tires
I would argue the opposite - which is why it's so egregarious.
A longer frame with a shorter stem and so a longer front centre is more stable for riding offroad and so racing offroad - this is what mountain bikes have all move towards - and if this has 57mm clearance, that should be the aim. Look at the last Mondice frame geometry.
A shorter bike is just more comfortable for old/unfit people who have to ride in an upright position.

Yeah... i am an old fat unfit guy... 😂
In the end, it comes down to personal preference.
-
shit geo. what were they thinking with 67 bb drop on a 57mm clearance frame?
just fix the 336s tire clearance and call it a day
-
He said they will have another option soon as well. I’ll post the geometry here when they have it.
-
TT 540 vs 540,4 ( 4mm )
Reach 376,3 vs 382mm ( 5,7mm )
Stack 559,8 vs 549,5 ( 13mm )
Head angle same
Seat angle 73,7 vs 73,9 ( 0,2 degrees)
Only bigger difference is the one that new has
Bb drop 69mm vs 80mm on the fm336 ( 11mm )
In my opinion..
If you're not a racer and like a touch higher position on bike +
Want that extra clearance for rocks to hit your frame..
Get the new one.
All those measurements are so small difference..
Take the measure tool to your hands and look those mm
😁

11mm difference in bb drop is not a small difference
-
That is a pity that it will have such high seattube(( The frame with big sloping would allow some flex of seatpost and would give more comfort. I don’t understand what will be the diameter of the seatpost - will it be uncomfortable aero seatpost or old good 27,2?
-

Like I said..
If it's NOT for racing.. it's just fine.
1cm more clearance for rocks .. and 1cm higher BB drob is not
That big of a deal.
I would rather chance the seat tube for shorter, so there could be more
Flex , and comfort.

No it's not fine. I don't even understand what's your idea behind this statement that low bb is for racing and high is ok for amateurs. No, it's not mate. I will even say it's worse. Because low bb gives you more stability and better control. Guys who race have way better skills and control then amateurs, so high bb for them would be less of a. Issue then for regular joes. Your another view that long seat tube = less comfort is also wrong. Sorry mate but you clearly know nothing about bikes.

Genuine question, why is it a problem for racing? Additionally, why don’t we hear all these concerns with the Cannondale Super X which has the exact same geo in a 54cm frame?

Standard seat post, 27.2

not for me... i don't race and i fucking hate low bb drop. i literally see no reason to ever have it so low if you arent running 23c tires. why wouldnt you want to be more stable?
-

Yeah same. I wouldn't want lower than around 80 and would prefer even more as I run 165 cranks.
I think road bikes should move to more bb drop too as tires have got bigger and cranks shorter. But changes on the road scene are even slower than on gravel.
With T47 eccentric bb you can increase the bb drop about 7mm but then you're locked into certain bb brands.

Nice, thanks...
Shorter seat tube aka ... Longer seat post aka flex aka comfort.
And I never said anything about amateurs or pros.. 😂
Wtf ..
Anyway, let's keep this page nice and clean.

My grevil also has
535mm TT
367,8 reach
563,5 stack
500 seat tube
And 72 Bb drop.. and it's nice to drive.
Models larger are only 67 bb drop

My size L '21 Revolt has 70mm bb drop. 25k km. It has not been an issue.
What I do like about the Revolt is that it has a hard plastic protector in place on the underside of the down tube. That protector is pretty peppered with rock marks now, more so lower down around the bb.
Anyway, the bb height is not the selective factor for me. The tyre clearance is. I can definitely nake it work. We will see it there is an alternative version with a lower bb. I can probably make that work if it has the tyre clearance too.
-
Weirdly even though SPCycle basically share many of the same open moulds, their new competitor to this has just been leaked and it has non dumb geometry that is appropriate for gravel racing if you are reasonably fit.
If you just want a bumbling bikepacking frame this looks a lot better - especially with the large central triangle for storage.

IMHO your central triangle assumption isn't correct.
Mondince FM336 comes in five sizes with a seat tube length from 440 to 550 mm.
Spcycle G028 will come in four sizes with a seat tube length from 445 to 550 mm.
With seat tube length being the most limiting factor when it comes to fitting frame bags into the frame triangle, there's hardly any difference.

Just to add one more thing to the BB drop discussion. Few years ago I had specialized diverge E5 comp with 85mm bb drop. I used it as a gravel and road bike with 28c tires. I really loved how this bike was riding and I never had a problem with pedal strikes. That's why I think current era road bike should have 75/80mm bb drop and gravel bikes even more. It makes the ride so much more planted and confidence inspiring, really like I'd during high speed road descent on hairpins. Great for those those tight corners. It's also great in terms of aero because your whole body is lower, so the drag is lower.

I’m getting the sense that some people may be overemphasizing the BB drop. It does matter, but it’s only one piece of the overall geometry, and it’s how all the elements work together that really determines how a bike rides. As has been mentioned several times, this is essentially the same geometry as the Cannondale SuperX, which has received excellent reviews. The main difference here is that this frame allows for up to 57mm tires, adding a lot of versatility. I’ve actually ordered one myself and am really excited to build it up. Jack also shared some images and the geo chart, and it looks awesome. PS Jack also mentioned that this has a chainstay protector and downtube protector.

Looks good, what's the pricing like?

The total was $815, including shipping, custom paint, and decals. I'm sure if you did a single color and no decals, it would become considerably less.

I agree with you. I really like the geometry. It’s aggressive and nearly identical to my Cannondale supersix evo CX, which I have raced on everything from single track to champagne gravel. Didn’t have any issues. I went with the FM296 which is supposed to arrive tomorrow. If I don’t love it, this will be my choice.

How can you call the reach and stack in any way aggressive? It's like a Dutch bike.

I don’t know much about geometry specific to be honest. I’ve have a Cannondale SSE CX and have ridden the SuperX and they definitely feel like aggressive race bikes.
Are comparing the SuperX to a Dutch bike? The SuperX is a fantastic gravel race bike. The BB drop wasn’t very forward thinking from Cannondale. Neither was the tire clearance, but this frame solves the more important issue with adding the ability to clear 2.2 MTB tires.

Does anyone know if they'll do top tube mounts? The renderings don't have them.
-
Does anybody know if Mondince had made this frameset already?
-
I’ll ask about both of these things and let you know what he says.

BB drop matters A LOT when it comes to stability at high speed and how easy it is to achieve this high speed. CX bikes have high BB to make it easier to jump over obstacles at low speeds with 33 mm tire, but this is a disadvantage for high speed cornering on gravel. The way bike corners with high and low BB is very different, and big tires will only exacerbates this difference.
-
Jack just sent me some videos of the frame. Looks good. I like the top tube under mounts.
-
This is really good looking too...
I'm between this and the 61mm clearance frame 😂
-
This looks super interesting to me. I have a Supersix Evo as my road bike which i really like.
Been thinking about trying a similar geometry as a gravel/bikepacking rig...given I want to build up a cheap Chinese carbon gravel bike, this might just tick the box.
-
This is really good looking too...
I'm between this and the 61mm clearance frame 😂
Me too… however this one, in the videos, seems a bit more aero looking? Don’t you think ?
-
Yes.. it does. The better look, and "enough" clearance is taking me to this frame
I think it will nicely take 2.35" thunder Burt tyres, or Speed one pros.
( They both under measure a little )
-
This seems to be the most aero frame with 57mm rear clearance, very interesting...
Would it be possible to get this frame without the bikepacking mounting points (fork and frame seatstays), just keeping the top tube bags and bottle cage mounts?

Yeah, they’ll do that for you.
They also just came out with another aero frame. Looks interesting but I’ll hold my judgment until I see the geo.
-
I dont quite get it. Are those two frame the same as the tantan's ones ? Is there a third company developping the open molds and selling them to producers like tantan/mondince ?

You are right! Last two Mondince frames for 700x57 tires are the same as renders of Tan Tan new frames for 700x57 tires.
-
Does the TANTAN come with aero integrated handlebars ?
Because correct me if I’m wrong but the MONDICE doesn’t ? I wish it would it makes things much easier to receive it all and have the handlebars compatible with the frame 100%
-
Hot off the presses

Mondince makes handlebars and can include them.
I really like that color, frame looks great!

The rear triangle is exactly the same as the new sp cycle G028, fork is also the same between the two.

Downtube shape/profile seems to be the main difference between the two frames, with this Mondince one looking more aero...
-
Geometry is not the same. The Mondince appears to be a little less aggressive in the stack/reach department. Feel free to correct me if I'm wrong, I'm still pretty new to gravel/road geometry.

I just noticed that Mondince's website now has a page for the FM346 - it's not for me exactly but I thought I'd mention it.
