I've been running Crossmax SLRs on a Lefty DLR2 SL (Taurine Team 07) for last 12months and have never had smooth rotation. I have repeatedly tried to re-install the wheel on the axle with teflon grease, grease packed around rubber o-ring on bolt, no o-ring, etc, but at best get about 1-2 revs following a fairly hard shove. Anyone out there got any other ideas??. Getting a bit frustrated that Mavic's best can't do better. Also rear manages a poor 3-4 Revs? Do these need maintenance/adjustement? Any advice gratefully received?
