Hey,
I just built up a winter fixie beater and when i ride it, the cog seems to slip when im stop using the pedals...its seems like it is not tight...i checked and its pretty tight so im not sure why this is happening....It slips when i stop and then when i start to pedal forward, it does the same thing...its quick, like it doesnt happpen continuously when i ride, just the first pedal stroke...is it just my lockring and cog arent tight enough? thanks for advice
