scanning the isles of my local swap meet with afew friends of mine today, was a good bike ride and it was good weather (overall good day if you dont count that Joseph's bmx bike got stolen even though it was locked up) and i saw what i have been looking for for afew years, plastic mags. well we know thay dont really exist like that so everyone else just calls them wheelchair wheels (potato pototo) asked how much and the guy said make him an offer "will two bucks and a Rockstar get them for me?" "what kind?" "lemonade" "theyre yours for the Rockstar" so i had a smile plastered on my face for the rest of the day. but now that theyre here im wondering, how am i supposed to get a sprocket on them? i thought about cutting a hub in half, corning out the centers and putting it back together, then i googlerd it and found someone on here who had done it successfully, so how have you guys added sprockets to these wheels? thanks!
