Re: TanTan FM10 29/27.5+ The modified seat stay takes the full range of motion and still has about 2-3mm distance to the 200mm shock mount at the critical position. So yes, they fixed the problem.

Re: TanTan FM10 29/27.5+ Bike is ready. Looks like a dropperpost is a must have.

Shimano Deore XT FC-M8100-1 Kurbel 1x12, 170mm. 52mm chainline. 34T Chainwheel.
Shimano Deore Shadow Plus RD-M6100 12-speed rear derailleur
DNM AOY-36RC 200x55 rear shock

The fork should be this one:

36mm stanchions. They say that it has 160mm travel, but it comes at 140mm. It is possible to change the travel to 160mm but I guess it has a good reason that it is set to 140mm. There are some reports about broken stanchions after flat drops. I removed one 10mm spacer to get 150mm out of the fork. Since I won't jump or ride super hard it's ok for now. Will switch the fork in the future.

Overall the fork is not as responsible as I wish.





I used many parts from my old bike. Tektro brakes, an old ugly saddle, pedals with some rusty spikes, handlebar, stem, tyres etc.

I bought two 160mm centerlock discs. Turned out the fork wants a 180mm disc, so I recycled my old 180mm Hope 6 Bolt rotor.  Used a reverse 6 bolt to centerlock adapter. Didn't worked out of the box and the rivets dragged on the fork. It was just a tiny bit. Removed 0,3mm from the adapter. Was enough to get it running without any drag.



29" wheelset. 30mm rim inner width. Continental Kaiser Projekt 2.4" on the front, Maxxis aggressor 2,25" on the back.



Bottom bracket is a ninja token. Runs smooth.


How hard do you ride this frame?


PS: Don't panic. I laid the bike down super carefully. Nothing touches the frame. :D

Re: TanTan FM10 29/27.5+ Small update on the fork:

It is possible to get better performance from the fork. I followed a tutorial on Youtube but can't find it anymore.

Basically I marked the stanchions on the wanted point of sag, pushed the fork to that point and locked it with cable ties. Then flipped the bike and minimally loosened the dampernut and airshaftscrew. Then pressed the airshaftscrew a tiny bit in until the pressure in the lower (negative air) could get out. (pssssscht sound)

I didn't expected it to work but I was wrong. It changed the performance of the fork a lot. From basically stiff on smaller impacts to "Ok.. cool. I can live with that".
