I have a Rock Shox Reba RL with 15mm TA. Starting yesterday it seems like I've loss most of the clamping force in the QR. How could that happen? Previously when I put the wheel in the dropouts, I would turn and tighten the TA until it was just snug, then I would clamp the QR down closed and I could feel it provide some good clamping force. It felt like about the same clamping force as a traditional 9mm QR. But when putting the wheel on yesterday I used the same procedure but the QR didn't seem to provide much clamp force at all. Even if I turn and tighten the TA hard, I still don't get much more force out of clamping the QR. I can still spin the QR on the axle when it is in the closed position, I couldn't do that before.
First thing I thought of was the TA conversion hub caps, but they all seem fine. The hub is Specialized Roval Control SL, TA is Rock Shox that came with the bike/fork.
