avid clean sweep xx centerlock rotors 185mm... I'm trying to put these on an xtr trail wheelset so they need to be centerlock. 185 is kind of a weird size but the scott genius is kind of a weird bike! I picked up the wheels from real cyclist back when they were on sale for under $400!~ I'm using 6 bolt adaptors and I dont want to be. I can find these for under $50 Does anyone have a used set? or a good source? Thanks!
