Proper Magnalite back wheel sucks , do not buy it , i made the mistake of buying it because ive never heard anything about proper as far as how their parts hold up , i had the wheel for like a 2 month period , the bearings in the driver are shot , i ride pegs and i know how to grind very well its not like i was learning on it or anything , unless you are a pegless rider that is smooth i do not recomend this rim to anyone at all.
