Chinese Carbon MTB > 26er & 27.5 (650b)
27.5 build FM356
BS650:
Anyone try a FM356 out? Technically a 27.5+ but I'd run it with some 2.5s.
Curious if anyone has experience with this frame? I was geometry and kinda has a Pivot Mach 5.5 vibe.

I would also love to hear from anyone who has this. i am looking at this frame or the FLybike FM336-B. looking for a 140-160mm 27.5 bike. any other suggestions would be great! thank you

I don't have one so take this as you wish. I know it says 27.5+ but it is actually a 29er frame, my experience with using these type of 27.5+ / 29er frames as that when you run them as 27.5+ the bb is too low and pedal strikes become an issue, particularly if you would normally be using 175mm cranks. Obviously dropping to 172.5 or even 170 mm does buy you a little more clearance but again, from my experience that is a compromise and pedal strikes still occur.
Dropping to traditional 27.5 wheels, even running 2.5s, is only going to drop the bb down lower still so I would not be recommending this.

This was actually my main reason for looking at the flybike fm336-b. It has the same BB drop as several other 27.5 specific frames at about -5mm. The fm356 has a -25mm drop. I think this would still be doable with a 170mm crank. There are others bikes that have similar geo as a 27.5

Yep, sub 10 for 27.5 and sub 15mm for 27.5+ is what I would be looking for depending on travel.
