I have the same issue with my Hillborne. I assume they use the same studs as the QB. The problem is more radial slop than length-wise slop as was previously mentioned. I had terrible brake shudder, because when the brakes hit the rim, the cantis would rotate enough on the stud to remove the little bit of toe-in that they had when not engaged. I ended up re-postioning the pads with a lot of toe-in and that solved the problem. Other than that issue, which I'm not sure is due to the under sized stud or oversized brake bushing, I love the CR720s.
