On my fixed gear when I am trying to track stand I feel like a little click in pedals when I go from forwards to backwards. I have had this problem with my mountain bike before and it was just because one of the chain rings was loose so I tightened and it was all better. I've have tried that on my fixie and thats not the problem. Ive also made sure the pedals were tight.
Could I have a problem with the bottom bracket? or maybe the cranks are loose?
thanks in advance!
