I was in Brooklyn this morning to take a ride, after half a block Im shifting gears and the chain goes out the gear, and suddenly something happenes to the whole metal thing that holds the chain on the back wheel, it gets screwed up and contorted till the point that gets stuck in the wheel’s spokes….now I don’t know if this means I ave to change the whole thing and it has just to be fixed on the spot…I just knopw that the guy who repairs this stuff near my house is a f….thief….and I don’t wanna go there unprepared…do you think Im gonna have to change the whole gear system? How much would it cost? and what would be a reasonable price for just fixing it without changing? thank you
technically the gear arm is bent…
