MTB Frame Compliance Analysis & Discussion

Hey, I’m Ryan Burney. I’ve spent eight years as an engineer for full-suspension bikes, working on some fun projects, like developing the flex Horst link for the Cannondale Scalpel and being lead engineer for the latest GT Fury downhill bike.

In his analysis of roll…he doesnt seem to acknowledge precession.

I thought precession in a wheel was due to only one side of the axle being held/fixed.

No, it doesnt care, it functions as a gyroscope due to being a spinning disc. Thats all fine and dandy, but when we start talking about roll, thats definitely going to be felt in 90 degrees in the direction of rotation. Im not sure his ideas make sense here, since it’s going to result in some of the things he said he doesn’t want.
