hi i had my fixed gear over 4 to 6 months now,one day i took it to a shop to get my wheel fixed and after a few miles on it i started to notice that its getting harder to pedal. at somepoint i couldnt anymore... seem like the chainset or the bigdisk thing that holds the chain is hitting the chainstay( sorry a noob when it comes to bikes ). seem like the old man at the shop screwed me pretty good...i ol'most got in a accident when the bike locked and i couldnt pedal any more...








so if anyone can help me please do...if u'd like ill post some pics
