Is it typical for cranks to loosen up when riding fixed?
It seems my stock Sugino 75 (from a khs 03) non drive side crank arm started coming loose. It took me a couple of days to figure out what was happening, at which point i walked it over to the bike shop. In the hour walk, it loosed almost to the point of falling off. they tightened it up and i was on my way.
before you ask, yes i should have had a 8mm wench to tighten it, but i didn't.
so, it started to come loose again. (still putting off getting a 8mm wrench) I went to a different shop to get it tightened and figure out what the problem was. He said the arm was starting to round out / strip and that i would need to replace it. In the mean time he suggested i tighten it as much as i can everyday even if it doesn't feel loose
Its barley a year old just wondering if this is normal?
Is putting off the replacement going to to f up the drive side and my bottom bracket?
i'd like to avoid replacing it, but it seems like i would have to take it off to see for sure if its rounding off.
if its relevant im about 230-240lbs, im guessing its a factor, more stress/torque on the drive train.
