I was kind of on the fence about this one, and in prep for a road trip last summer I replaced both upper and lower rollers with new bearing-style rollers. About 5000km later, winter rolled around and I decided to tear the DR down to the frame. This is what the rollers looked like. Lower on the left, upper on the right:
The evidence of excessive pressure and wear on the upper roller is pretty damn obvious considering they were both installed at the same time. Needless to say, that upper roller is NOT going back in the frame as I build it back up.
