I primarily want to do dirt riding with my "x" so I'm changing it to an "r."
That said, I would still like to enjoy it occasionally as an "x."
I was just about to change the rear sprocket to a 48 but obviously can't use that with the "x" sprocket.
What does everyone else do in this situation?
FYI, going with D606 tire on the "r" rim.
BTW, I did look through the archives, and found a few "45 will work" but sounded like speculation re: chain slack.
