umm.... you cant. You could buy a new hub. I have a brand spanking new system ex hub also for sale. But if you are after a budget wheelset, this will add up. Let me know. 55 is not a bad price.
I've got a langster wheelset up for grabs, BUT, the flip (or flop?!) (fixed) side has the threads stripped so it can only be used as a single speed wheelset. Can have front and back for £55.
MePower, stick some risers on that and it will look awesome, now, it looks shit.
Guy with the barspinable Pug. Max respect, that is awesome!
