I'm one of the testers for the DT Swiss E-1700 wheels (see http://bb.nsmb.com/showthread.php?t=162085 ). I use a 30T RF NW ring, with a 42T one-up on the rear. I'm finding that the One-Up ring is starting to really dig into the hub body. I'm also seeing the One-up teeth that fit around the splines on the hub starting to wear, and shifting is starting to lag.
So my thought is that the One-up ring needs to be replaced. Has anyone else replaced these oversized rings for the same reason or do they only replace when they see shark-fin teeth?
However, since the hub is already galled, would I be forced to replace the hub body aswell to stop the new cog from rotating slightly into the grooves (again impacting shifting), or is there another solution I'm not aware of?
