i'm hoping i'm not thinking clearly and this is an easy problem to fix. i started hearing this weird noise when i would need to backpedal hard to come to a stop..you know, the stops that don't need a skid but you need to slow down. well i decided it meant i should probably take my bottom bracket apart and give it some tlc. i greased everything up and put her back together..problem solved? i thought so! the next day i try to stop the same way and it makes the noise again so later that day i take off my crank and my non driveside bottom bracket thingy is loose. i tightened it and then today it seems like the problem is still there.. any ideas?!
