Patrick makes some good suggestions. It sounds like something is preventing the drive side from closing enough to grip the dropout. As Patrick suggested, make sure the axle isn't extending beyond the dropout, which would make it impossible to clamp all the way. This can be fixed by loosening all the cups and recentering, or by adding a thin washer on the drive side.
You might also try taking the spiral spring out of the drive side. It could be interfering with the clamping. It's not needed except to make it a bit easier to put the wheel back in. Finally, make sure both dropouts are the same thickness. If the non-drive-side dropout is thicker, it could be keeping the drive side from clamping down enough. A washer on the drive side would fix that. --Eric N On May 6, 2012, at 7:59 AM, PATRICK MOORE <bertin...@gmail.com> wrote: > From the photo I saw on Amazon, the current XT QRs are internal cam, > so that eliminates one possible cause. > > You might also look to see if the hub axle is a bit too long, > preventing the QR from clamping down fully on the dropout plate -- > tho' if you are distorting the bearings this isn't your problem. > > I would guess that the contact surfaces or at least one of them on > these current XT QRs is aluminum (saves weight, you go much faster) > and does not grip as it needs to. > > Last option: get another, old-fashion QR like the early '90s Shimanos > -- all steel.
