Hey guys

Have a first gen XX1 rear derailure, and noticed some serious drag in the system the other day, so pulled it apart and found the lower guide wheel bearing to be the issue, perhaps the seal has been compressed into the race? Not sure, feels smooth still but not spinning freely.

Anyhow, its a strange bearing size 5626 LU/C, never seen or heard of it. And cannot find a replacement either, and haven't pressed the bearing out to measure the OD.

The replacement wheels are $100, i was crazy to get a bike with XX1, and id be that much crazier to spend $100 on a F*&%NG roller wheel. Common!!

What i am wondering, is if anyone else has tried replacing one of these with any success? And if so, what bearing did you use as a replacement.

BTI has them listed here:

and the black box version:

since you can't order directly from BTI, just punch the part numbers into google and there should be some online retailer who's got 'em..

5626LU bearing is actually a 626. available at any bearing store just make sure you get a SEALED version.
