Post by: Crash217 on August 18, 2023, 12:41:58 PM
Spotted this over on Instagram, several posts and reels of their testing of the frame on a couple of their pages.  No other details yet that I've seen.

TanTan - Seraph FM121 XC - 120mm Full Suspension (at least thats what the post says)

Interesting (i.e. good!) that they are doing tests and sharing the videos before they list it / put it on pre-sale... unlike some other frames recently mentioned on this forum ;p

yes, then this frame is 100mm stroke

Hi , any idea if it gets 2 bottle cages or not. Looking for a xcm mtb travel 100-120mm travel full sus bike frame , that is really good quality and must have 2 bottle cages. Any suggestions on a frame
Thanks

RC 440 mm...
440RC a bit long for my liking since I am size small maybe medium - longer than my enduro sled in fact.  That looks right for L/XL sizing.  Rest of the geo, looks spot on, except the seat tube is also  tad long, so many need will run a shorter dropper post.  Let's see if it get 2nd water bottle mount and how the suspension kinematics playout.

Why do you say that it’ll be 100mm travel? The geo chart you shared (the same one they sent me) specifies 120mm. They’re calling it the 121 as well. Looks like it’s pointed at being the Epic Evo rather than the Epic.

Zoom in on the picture. Not only does it have space and mounts for two bottles, the down tube mount has three studs to allow for two different cage positions. It could probably take three bottles.

no flat mount. Is the shape of the down tube slightly changed in the bottom bracket area? Slightly different dropout shape? Modified suspension link?

Hi guys , any idea of quality of the tan tan mtb bikes. Are they on par or better than the other manufacturers . ( hongfu / lightcarbon /carbondo ) type brands. I saw the bigger bikes come with 2 bottle mounts. My favourite so far for xcm is fm138hongfu and fm121 tantan. Would like your opinions please.

I've ridden a Tantan/Seraph FM078 for almost three years with good luck so far. I'm lightweight and don't ride too rowdy, but I ride a lot and the FM078 has held up just fine.

I am also curious about this thing. If it comes in more affordable and is good quality then I may consider it over the SPCycle M868. Unfortunately there is little to none information out there.
Has anyone bought and reviewed/inspected it?  ::)
One thing i certainly don't like is the pressfit bb on this thing, but i could live with it if the frame is otherwise good.

Riding position length (saddle to bar) is within few millimeters compared to Epic clone size Large (same stem and saddle).

Bottom bracket height with 120 mm Sid and Kenda Booster pro 2.4 tires is about 33,8 cm.

It feels slacker than Epic clone.

I can tell more and attach pictures if needed..

No, it's not the same geometry at all. The closest frame I found is the Scott Spark RC. what do you think?

Can´t say about long term, but term perhaps. I enjoy riding it more than Epic clone. The rear suspension is closer to RM Element than Epic clone. I don´t like working on headset cable routing but it looks good.

They seem to be cartridge bearings. I would suggest using blue Loctite (or other brand stuff) on every pivot bolt. They can come loose while riding.

I ordered a large from TanTan via WhatsApp for $733 shipped (headset and thru axle, UPS air shipping, paypal fees). The frame received some sort of impact in shipping on the top of the head tube and is visibly cracked. TanTan was quick to respond, requested I file a damaged item claim with UPS (they did as well), and they say it should take about 20 business days to get another front triangle ready to ship to me.

Hopefully they pack the frame(s) better. The headtube just had a layer of foam wrap and bubble wrap so it's understandable how the damage occurred. I would say thoroughly check the frame when you get it.

I suggest you also get blue thread compound and use it on every pivot and shock bolt. They have come loose while riding. The only negative thing I have found so far is the chainstay tire clearance on side of the rear tire. Luckily I don´t like mud fests..

good morning. sad update. my frame hasn't arrived yet. it seems that the package is missing here in italy.
i am continuously contacting the italian transport company dpd but they are not giving me any answers about it.
vivian has been hopeful for now and has given me the telephone numbers for assistance but i fear that i will no longer receive my frame.
to make the situation worse now vivian is on holiday for the chinese new year so he is no longer answering, i feel abandoned by everyone, i don't know what to do.
now exactly 2 months have passed since the date of the order and payment, the painting time had already been about 1 month, now problems with the shipping and finally the chinese new year.
this thing is bothering me a lot.
what do you think?

I'm also having issues with my frame. I received the replacement front triangle but found issues with the rear triangle. When I was disassembling the frame to transfer the front triangles I found that some of the pivot hardware that threads into the rear triangle was cross threaded and damaged. I also found that my rear caliper mounts were not threaded (tapped) and the other was full of hardened debris. Pretty disappointed in the frame and service up to this point.

I would try following up with the shipper that your tracking number is associated with. When my front triangle was damaged she did contact the shipper (ups) and I also filed a damage claim with them before sending me a new front triangle. There should be insurance on the frame so hopefully if it is lost she can get a new one to you.

as for the brake thread I would advise you to go with a m6 threaded male to eliminate the debris. as for the pin the thread is ruined but not irreversibly, mount it with a not exaggerated tightening copy and use medium liquid thread lock.
my package is managed in italy and europe by dpd, I have already made a lot of complaints but the answer is always the same it was lost here 50km from home. dpd tells me to contact the sender but because of new year's eve now vivian is not answering....

Hello friends.

We received our frames, they look amazing. But the quality of the bearings is very bad. I have to change them all

We paid for it on November 5th, and they arrived on January 19th.

They look very good quality, except for the bearings, even the one on the black linkage is noticeable that it jerks, it doesn't turn properly, since the bearings are bad. But that one is a 10*20*5mm and it is difficult to get in Spain.

When I have it fully assembled I will post more photos, mine is black and white

hi, i'm glad to hear that your frames arrived. i see that for you too the delivery time has reached 2 months. did you also have shipping problems or is all this time due to a delay in shipping? unfortunately my frame has been stuck since january 15th dpd the shipping company can't give me an answer they don't know where the package ended up. anyway congratulations they are very beautiful, we await photos of the assembled bike.

as for the brake thread I would advise you to go with a m6 threaded male to eliminate the debris. as for the pin the thread is ruined but not irreversibly, mount it with a not exaggerated tightening copy and use medium liquid thread lock.
my package is managed in italy and europe by dpd, I have already made a lot of complaints but the answer is always the same it was lost here 50km from home. dpd tells me to contact the sender but because of new year's eve now vivian is not answering....
The one in the picture is the one that is almost completely untapped/unthreaded. It appears it left the factory without being tapped. The other could be chased with a tap to clear out the debris but it's still very annoying.

Hi all,
I’ve been looking at the Tantan FM121 as a potential frame for my next build. It looks good and seems to check a lot of boxes for a full-suspension setup. However, after taking a closer look at the design, I can’t help but notice something about the rear triangle that raises some concerns about its durability and functionality.

Does the Geometry Add Too Much Stress?
From what I can see, the seat stays look relatively short, while the swingarm appears longer than expected, with a flatter overall angle. This design could cause the swingarm to travel in a larger radius than the rear triangle, which might not align well with the suspension’s intended motion. Can anyone who has this frame test if you disassemble the swingarm and the rear triangle if they move the same radius.

This mismatch could lead to some flex and stress in the rear triangle. If the swingarm is forced to move differently than the linkage was designed for, it could create excessive tension and strain on the rear end of the frame.

Potential for Restricted Movement
Another point I’m concerned about is how this might affect the frame’s ability to move freely. With the geometry as it appears, the rear triangle might be under constant stress, making it harder for the suspension to pivot smoothly. Did anyone of you check if you can move the rear triangle freely if the Frame is assembled without a rear suspension because it should move without any resistance to the whole 120mm.

This could result in:

Stiff or restricted movement at the pivot points.
Reduced suspension performance, especially on technical terrain.
Long-Term Durability Questions
What worries me most is the possibility of long-term wear and tear, because if the rear triangle is under permanent tension the frame is more likely to crack.
Has Anyone Experienced This?

For those who already own the FM121, I’d love to hear your thoughts. Does the rear triangle’s geometry hold up well in practice, or have you noticed any issues with flex, stiffness, or wear? Does the rear triangle move smoothly, or does it feel tensioned?

I’m still considering this frame, but these potential concerns have me hesitating. If you’ve built or ridden the FM121, please share your experiences .
Thanks in advance

Hello friend.

This frame was manufactured by the Megamo brand in Spain. I'll send you a complete video of the Megamo track, since this frame is the same one in operation.

The video is in Spanish. Greetings.

I haven't finished assembling it completely yet to go out and try it. As soon as I finish it and try it, I'll give my opinions.

Sorry guys.

I have a question about how to place the steering bearings, for those who have assembled it could you help me?

The 8mm thick steering bearings go on the top, and the 6.5mm thick one goes on the bottom?

I think I assembled them wrong and there is a little play

Post by: akuutti247 on January 31, 2025, 12:16:55 AM
Hi

On all the bikes I have ever serviced or assembled the lower bearing has been the bigger one. Usually the diameter is also smaller on top, but these straight tubers have the same diameter. I can´t disassemble the FM121 now because of work, but i think the lower is bigger.

One side of the bearing has curved edge and the other side is flat. The curve side goes towards the frame.

Thanks for answering my friend.

Yesterday I was looking at the geometry of the Hongfun 138 (I know it's not the same one) and it says that the big 8mm one goes on the top and the 6.5mm one on the bottom.

I'm going to try to change it, since the steering has a little play. And I see that it lacks some pressure so that the inner ring fits into the bearing and doesn't move when tightening the upper screw of the fork.

Since it's Chinese New Year, they don't respond

as for the flex of the seatstays I don't know what you mean by very hard.
another question, is the handlebar the one supplied by seraph? if so could you tell me what length the stem is?
do you have some other photos of the handlebar area I'm interested in understanding how you passed inside the handlebar with the tubes. thanks.

Yes that frame has flex stays. I don't have that exact frame but have had many with them and there can be some resistance in getting the suspension to cycle through its travel.  It should not be rough but should take some effort. I would not call it very hard but if you flip the frame upside down the rear triangle should not cycle through on its own. I would be suspicious if you could barely move the suspension. That does not seem normal to me.

Hi friend.

I bought that handlebar separately. It's the new one they've released, the wiring runs completely through the interior (I'm attaching photos) and it comes with 6 height spacers included.

It looks very nice aesthetically, but it's a lot of work to run the cables once the covers are cut.

They come with a width of 80 cm, I cut it to 76. and with a length of 70/80/90/100/110. This one of mine is 90. with an inclination of -10.

If you have any other questions, feel free to ask.

I hope that when it arrives it doesn't happen to you like it did to me. They painted all the bearings, and I had to buy new ones and change them. I wrote to Rose complaining. I suppose that when they come back on vacation she will see it

Another thing that happened to me. The shock absorber shaft screw is 7.6mm and not 8mm, so it has a small, very minimal play. I have ordered other screws that measure 8 mm correctly. I have temporarily solved it by making a small cover.

If you have any questions, I will be happy to help you.

Thanks for answering my friend.

Yes, you can't flex the travel of that frame with your hands. Once assembled and applying pressure with your body, it does flex the seat stays. I like that with the suspension closed it is very very rigid and rides like an airplane. I still need to test it further.

thanks, I actually don't like the handlebars very much, it's quite wide in the central part. The passage of the tubes inside instead seems perfect, but you have the levels that are designed specifically, I have shimano and the curve of the tube will probably be very narrow.
another question, I also have the remote of the telescopic seat post, in your opinion do 2 sheaths pass inside the handlebars?

Hi friend.

Yes, with the SRAM Stealth brakes, the handlebar looks much more aesthetically pleasing.

This particular handlebar is 9 cm, with a shorter one, it feels less wide.

And yes, two tubes go through without a problem. My friend has a SRAM cable shifter, and the 3 cables have been passed through. I couldn't tell you if 4 of them fit through the inside of the tube and the cable guide system, but 3 cables do go through.

Hello friend.

I think it's a botch job that they send you a bolt with a smaller diameter than the hole... and even more so knowing the function it has. I hope that the seller Rose answers when the Chinese holidays are over.

I have asked many sellers, and none of them confirm that it can measure 8mm, only one, but the head is too big.

I'll send you the link of the one that I took a chance on and ordered, but it hasn't arrived yet.

The only thing I've done is put a cover on the bolt and now it stays consistent and doesn't match.

Thats exactly what i meant in my previous post!
So that the swingarm seems to Go in a different direction than the rear triangle which causes the seatstays to flex enormously ( Must be around 4-6cm according to the Frame geometry ) Normally Even with flexstays the rear triangle should move quite free without a Suspension but in this case it seems that it doesn‘t. This also causes a Lots of tension in the bearings!
And in the worst scenario the Seat stay could brake.

Please let me know your riding Feedback
Best regards

Hi friend

I haven't been able to test the bike much yet, but the little I have tried it on and adjusted the SAG to 20% it flexes very well without any opposition.

I think the flex it does is a maximum of 4 cm, 6 cm would seem exaggerated to me.

Greetings

I would also like to ask if anyone else has bought the shock absorber shaft, so that between us all we can get the correct one. I hope that Rose gives me some solution, and I will tell you something about it.

What I don't understand is how a factory like Tantán, which is a manufacturer of other brands, can't see that where the shock goes it has a diameter of 8mm and puts a 7.6 stem in it...

It's not going to be a stem of exactly 8mm, there's always a small margin, but 7.6 seems like too much margin to me and more so where it has to work... more than anything, because you can notice the "clack" of the play it has.

As I said, I made a cover for it and I "solved" it but it shouldn't be like that.

Good evening everyone.
I finally solved or rather almost solved the issue of my frame that no longer arrives.
finally the shipping company admitted to having lost the package and issued a refund procedure towards tantan.
Vivian who has just returned from the Chinese New Year holidays has agreed to follow the matter.
now the proposal was to have another frame but the delivery times to have it the same were another 2 months only because of the painting.
I decided to have an unpainted, raw one sent to me immediately, also the handlebars were no longer available in the size I had requested.
to speed up the shipment I gave up with a refund, which will be given to me upon delivery of the package, the painting and the handlebars.
they sent the raw frame on the same day, now I hope to receive it within 2 weeks..
It was really a bad experience, I had ordered it in mid-November, I can't tell you about the messages and the endless exchange of emails.
Now I hope it gets to me asap, I still have the problem of having to find someone to paint it for me, and I certainly won't spend 110 dollars.
and then I have to find a handlebar, then I'll finally assemble it...

I asked you about the cable routing in the handlebars, well the handlebars now don't arrive and I have to buy one on aliexpres, but I would like to get one with only partial cable routing because I think that with shimano brakes the tubes are less forced.
I would like the syncros like the one on the scott spark but I noticed that the base of the headset is very wide and I'm afraid that it will then protrude laterally from the frame and be aesthetically ugly.
Could someone tell me the measurement of the upper part of the head tube? the external measurement.
or of the first conical spacer in this photo.

The size of the shock absorber where the valve goes is 22.20*8

The stem part is sent in the frame package.

Hi guys.

Rose from Tantan told me that they are going to make new bolts in about 15-20 days to correct the 7.6 mm measurement.

He told me to remind him within that time frame. They are going to correct the problem, apparently.

good morning everyone after exactly 3 months from the order, I finally received a frame to replace the one that the shipping company lost. this new frame arrived in about 10 days from shipping, but I had to give up the handlebars and the painting otherwise another month and a half would have passed. now I accept advice for the painting. I'm posting some photos of the raw frame the shock absorber pin that they sent me with the frame measures 7.9mm

Good evening everyone, as already mentioned the frame I received is raw so I disassembled everything to be able to paint it. if you want some photos or measurements of the bearings or pins ask for it. I also weighed all the individual components, for weight maniacs. The frame seems well made and finished quite well, but the bearings are full of carbon processing powder seem to me of poor quality, a bit of dancers. inside the frame is well cleaned and without scraps or cutouts of processing. one thing that left me amazed is the movement of the wagon. without shock absorber the frame struggles very much to make the whole excursion. the rear sheaths we said that they flex but I did not think so much. with bare hands it is difficult. I took a picture with the wagon disconnected, it seems that when it cushions it moves 40mm from the center of its natural trajectory. moreover the connecting rod has a considerable weight, according to me it is only covered with a sheet of carbon but it is metal. this weekand I proceed to paint then I have to wait for the handlebars but I will start to mount a few pieces, however I will constantly update you.

That's right, my friend. The bearings are of poor quality. I changed all the bearings. Could you put the measurements so we have them all, taking advantage of the fact that it is disassembled?

That shock absorber shaft is perfect, Rose told me that they were making a new one. I suppose it will be that one, and he will send it to us, and in black it is much prettier than in silver.

That frame in exposed carbon color, and in gloss I think it would be very very nice.

I have been able to try it and for now I am very happy with the performance of the frame.

I also think that measuring the bearings now is a good idea. I will try to measure them tomorrow, but I will do it without disassembling them, I will do it when it is time to replace them.

Today I tried a color and two types of transparent, one opaque and one glossy, they are both very beautiful but I prefer the glossy one.

regarding the brake hose and gear cable routing, don't you think those 2 holes between the frame and the main triangle are too small and restrictive during the movement of the frame? I'm considering opening a small window in the rear frame.

These holes are ideal, the covers fit well, but I do recommend greasing the cover a little so that it fits perfectly.

good morning, I'm finally assembling the frame, but I noticed an incompatibility between the shock absorber and the frame, let me explain better.
on the whole frame in the part where the shock absorber is attached, there is a small hole to let the sheath of the remote control of the shock absorber come out.
i have a fox shock absorber and when i try to insert it in the assembly seat i notice that the protruding part that houses the sheath of the remote control cable hits the wall of the frame.
in this way it is not possible to assemble this shock absorber.
i could assemble it with the red knob and the valve facing upwards but then i wouldn't know where to come out with the cable.
the only solution, and i ask you if it is possible, would be to open a recess or a hole enlarging the existing one so as to be able to connect the sheath well and when the shock absorber compresses the sheath guide can move freely also towards the inside.
 widening that hole I don't think it compromises the integrity of the frame for safety reasons I prefer to ask.
I attach some photos to make it clearer. thanks good work.

I haven't had that problem with my Fox Float DPS shock. But it is true that I don't think there would be any problem in enlarging the hole, with great care.

However, I know that I would tell Rose about those problems. He told me that we should let him know about any small details that could be improved. As happened with the 7.6 shock shaft.

I am in touch with Vivian, this morning she replied to me by sending a couple of photos. According to them the sheath should make a sort of S and go underneath. I am not convinced by this thing. Could you send me some photos of yours? Thanks

thank you very much for the pictures, from what you can see your frame is different from mine, between the wall where the hole is and the housing of the shock absorber sheath there is just 20mm that allow the sheath to bend to fit into place.
mine on the other hand has no space, the point where the sheath is inserted is against the frame so it does not allow the movement necessary to be able to move, and also the sheath has no space to move laterally.
I made a drastic decision and with a dremel I created a window by widening the hole all the way to the left so that the sheath can reach the cable attachment straight.
a lot of white dust came out.
now it is not perfectly aligned but at least I was able to mount it.
your shock absorber is different from mine I have the air valve and red knob located at the bottom and the blue lever at the top. you will struggle if you have to make adjustments.
mine was mounted on an orbea oiz in the same way.
then I had to invent the teflon bushing that goes to the rear attachment by cutting the original fox ones, I also moved the fork so as to have the screw with the head at the top because I had no way to insert it from below.
this assembly really made me suffer, it's true that shock absorbers are not all the same but in my case the space was really tight, impossible to assemble.
I'll post some photos to make you understand.

Have they modified the mould? My wiring outlet is not like this, I don't know if it's because of the size, mine is m

Having the shock absorber like this on my bike, if you put it with the rebound down, I already told you that the bottle hits. The idea of ​​the OIZ shock absorber is very good, but with a little skill and fine fingers it can be done. It's even worse to do it on a Scott Spark or Berria Mako of the new ones...

I don't know when I'll be able to test it yet, now I'm also having problems with the rear brake caliper.
My initial idea was to mount a 180mm disc with a 4-piston caliper.
I've now discovered that the 4-piston caliper hits the seat stay even with the 180mm disc.
What brake calipers do you mount? and what disc diameter?
do you have a photo of the detail to understand the spaces?
this assembly is making me struggle a bit, I think I won't test it before 2 weeks.

The specifications say it supports a maximum of 160 at the rear. Another user had problems with a 4-piston brake disc, talk to the Tantán sales representative. These frames should be prepared for 4 pistons, they will lose sales.

I'm fine with 2 pistons in my departure area.

I ordered a size M with 180 and it's great.

I think that these are improvements that should be made by listening to users. I don't need 4 pistons, but there are some areas that do. I know I'll tell Rose about it. Let's see if they correct it.

I'm happy with the price of the frame. I wanted to buy a Megamo Track, and with this model I decided to buy it at random, and save money.

Guys, my FM121 bike has started making alot of noise lately from the rocker arm area.  It could be the play of the rear suspension shaft, like someone mentioned it’s 7.6mm but it should be 8mm.  I dissembled the rocker arm today and found out the bearings went bad.  I built my bike late December of 2024 and the bearings already went bad.  It means Tantan uses shitty quality bearings there.

I asked Vivian for the size of the bearings so that I can order good quality replacements from the States, but she thought I was asking about the bolts.  She doesn’t know about the bearing.

Does anyone know the size of those bearings?

When I assembled the frame I saw that the bearings are of very poor quality. I assembled them anyway but I expect that they will have to be replaced soon. I am still finishing the final assembly but the noise at the shock absorber pin is already making it without having used it even once.

-dt-suisse d232 ONE telescopic seatpost wolf tooth components remote control
-pro stealth saddle
Weight 11.5kg (you could still remove a lot but for me ok)
Today for the first ride I did some settings, I will give you more exhaustive opinions later in time also because with this handlebar I have a lot of saddle-handlebar difference in height and I don't feel very comfortable.
However, the first impressions are already very positive.
I hope you like it and I accept advice for aesthetics and assembly in general.

Frame: Large
Rear Shock: SideLuxe Ultimate
Fork: Fox 34 140mm
Seatpost: PNW Loam 150mm
Dropper Remote: Ztto
Saddle: Ryet 3d printed
Handlebar: ToSeek
Stem: ToSeek 70mm
Grips: ESI Chunky
Brakes: Ztto M1 X4/X2

Rotors: Sram Centerline
BB: Shimano XT
Crankset: Senicx FM2
Chainring: Zrace 32t
Pedals: XT
Cassette: Speedao 10-50t
Shifter: Sram GX Eagle
Rear Derailleur: Sram XO Eagle

I haven't weighed it while fully assembled but it should be around 12.5kg based on individual part weight.

Ride quality is pretty good. As previously state, the bearings are definitely garbage so those will need to be changed out shortly.

How do you feel about the 140mm travel fork?
The bike is very nice overall, it has a less light assembly than mine, more in "enduro" style.
How does the saddle behave? Doesn't it flex?
The only criticism is that bottle cage...... it deserves carbon

So far the "overforking" is great! I got it used with a 140mm air spring and figured I'd try it in the longer configuration before reducing the stroke if necessary. I know.. it's the only bottle cage i had laying around.
I wouldn't describe the saddle as flexy. I have one on my gravel bike that i have liked and they're only $35.

Can you fit 2.4s in the frame

I first had a 2.4 Kenda Booster Pro in the rear (28mm inner width rim). The seat stays have a lot of room but chain stays are quite narrow. In dry conditions it works ok, but I wouldn´t do long extra muddy rides. Now I have a 2.35 Renegade Control T5 and it fits much better in the chain stays.

I have a 2.4 Maxxis Dissector on the back and it seems to fit ok. Might be an issue in really thick mud but so far there's been plenty of clearance. For reference it does measure pretty much exactly 2.4".

I reassembled the frame pivots with thread locker before taking it out on the first ride this weekend. I didn't do the main pivot so I don't have the bearing size but the rest of the bearings are below:

6800du 
6801du
6800.2z

Quantity 2 for each one.

Thank you!

What kind of fork is this? Does it have variable travel?

It's a 2019 Fox 34. You can't adjust the suspension stroke on the fly but you can swap the air shaft assembly without too much trouble. I'm pretty sure the current Fox 34 is the same way in just swapping the air shaft.

Hi guys. Rose sent me the modified screws today.

They finally fixed the screws and sent them. The service was very good on their part.

The truth is, these screws have a better finish than the silver ones.

I understand that's how they fix the flaws.

If you don't know, read the forum.

Best regards.

very good, i ordered one on aliexpres but i fear i will have the same problem with those too.
these ones she sent you seem great, they have increased the tolerance a lot they are 8.20mm.
let us know if they fit as soon as you mount them. thanks.
