I have a Blackburn Fluid trainer. Last night, fornthe third time I fell off the damn thing. Well really my bike came out of the mount then I fell. I tighten the mount so much that I can see the stand bending. I think maybe its the type of QR that I have, its one of th external cams, but I really don't know whats up. Anybody else have this kind of problem and what did you do about it?
