So just got my TR250 together...setup in the shortest chainstay, lowest bb, and slackest head angle (with an additional 1 degree negative Angleset cup)
Issue: Under hard rear breaking, in a very steep section, the forces applied to the rear wheel won't allow me to turn my cranks until I let up on the rear brake. It's as if so much load is being put onto the wheel bearings, or freehub that it binds it up. At times I want to turn my cranks one way or the other and they don't want to move easy until I let off the brake, then its fine. It's a Stans HD hub on a Flow rim and new.
I've been told this is a symptom of "brake jack" and wondered if anyone else has had this issue in this configuration? I always understood brake jack to affect suspension, not drivetrain. I've never experienced my drivetrain issue before in all the DH bikes I've owned so I'm stumped.
