I have a set of Mavic Open Pro rims that I've ridden for around a year. I have a purely cosmetic issue with them, but want to see if anyone else has had this happen.
On the rear rim there are little abrasion marks on most of the braking surface. I don't run a brake on the rear. I do have one on the front, but the front rim is clean and looks new.
I can't figure out what these little pock marks are from? Maybe a thin coating on them that is wearing down/off? But again, I don't brake on this rim. I clean them with rags and occasionally a little rubbing alcohol. None of that explains why it would only happen to one rim.
Nothing functionally wrong, just wondering why my sleek, smooth rim is breaking out. Puberty maybe?
