yesterday i started hearing a clanging sound while pedaling my singlespeed. I do not hear it while coasting and it is also not always there. i can't figure out what makes it start or stop. it's driving me nuts
it sounds like something is hitting against something else and has a metallic twang to it. there is nothing rubbing any of the wheels or spokes. chain is lubed and tension is good. nothing feels loose.
i recently swapped a new freewheel and it rained yesterday, could those be contributing factors?
