I just kinda wrecked my riser post clamp tonite, right before a race!
All I did was drop the bars a bit, then went to tighten.
It probably was up a bit because the screw wouldn't torque up. But in backing it out, it got a little cross threaded.
Took it all apart and found that the clamp seating area is a bit damaged from previous work. Plus it was not greased up - it should be so the wedge can slide.
The stem pinch bolts were loose and rounded as well (the ones to 5 nm)
I used the Cervelo supplied torque driver & it could be too aggressive. I have an automotive low-torque 1/4" ratchet and it went quite a bit easier when set at 7nm.
It's OK for now, but I am going to order a new riser post clamp and a few other bolts that are rounded off.
