You'd be better off buying a used wheel or wheelset off CL or ebay. I saw some new Weinmann DP18s, all black, go for $113 on ebay the other day. I got my mavic cxp-22's on formulas and DT's with tires, EAI lockring and 17t cog for $75.
If the wheels not hopping then the axle is probably fine. Are you riding brakeless on this thing? Why do you keep getting hit by cars?
no im not riding brakeless...well technically the first time i got hit i kinda was because i have cheap tektro brakes and that day i was riding in a parking lot structure and i picked up some food so my hands were a little full. anyway Im riding say west and well this guy in a car was coming from the south so he wasnt even going fast and neither was I in fact he couldve braked but where he failed, i tried to brake but when i squeezed the brake i squeezed it to hard leading me to roll on his hood. Anyway im going to take my bike to the shop this thursday and hopefully fix the problem
