Chinese Carbon MTB > 29er
Dengfu M06
Stef27:
Hello
I read that in case of tailgating of the damper, the rear axle can come to touch the frame.
What do you think ?
Is there something to modify ?

I have read about that as well. I don't know if DengFu made a change but with my bike when the shock is completely bottomed out there is plenty of clearance for just about any size tire. I don't know why that owner had that issue.

Will try to resurrect this old thread, just in case anyone cares to continue the discussion on the linkage and suspension of the frame.
I just decided to measure the leverage ratio on my M06 - which is the awesomest bike I have owned btw - because I still have some trimming of the rear shock to do.
When I drew it in Linkage the leverage ratio is very progressive, but that has not really been my feeling riding it. The measurements tell me that it is a completely constant leverage ratio of about 2.75. I trust the measurements (23 measurements of shock compression and wheel travel, regression line completely linear, with an R2=0.999, line through the origin), but not my linkage drawing. In Linkage I was not able to draw the little swing arm between the seat stay /rear triangle and shock, and I guess that swing arm actually bends the seat stay during compression. And that might linearize the shock - wheel travel relation.
Any thoughts on this?
What shocks are you using? I am using a Manitou McLeod, which is probably a great shock, but I have a hard time finding a single rebound setting that makes me happy on every trail. I will probably change the shim stack eventually, but decided to measure the leverage ratio to help me think about if I would be helped by a larger can on it.

I also tried to draw it in Linkage but could not finish it to spec because of the seatstay flexing instead of pivot. I'm thinking about pointing a gopro to the suspension and see how it behaves.
I also have a sussmybike that I'm waiting for years from kickstarter, that should help suspension setup.
So far on the same page, love the bike, but when I look at the bobbing while pedaling it does not seem optimal.
