Since this thread is near it end can I ask and ancillary question. I just added a Tubus Cargo rear rack (from Wayne) on my '07 Trek 520 and the Rear V-Brakes are rubbing slightly on the rack arms that attach the rack to the mounts near the seat clamp (I know it's a bit lower, but not to be confused with the mounts near the axle). It doesn't make them non-functioning, but it definitely rubs.
Any suggestions on how to remedy?
Thanks
Ryan
