Hey I am building up a fr-202 flyxii hardtail. I did not quite go into full research mode before making the purchase but not a huge deal as I got an awesome deal on a frame from craigslist. I have 3 extra sets off wheels but they are ALL 142 spacing! I bought a cheaper set of Bontrager wheels that do not offer 135mm hub caps and was wondering if anyone has grind down the caps 3.5mm on each side? Seems like it is an easy solution. I have a thru to QR release adapter.
