crank/bb problem
I just upgraded to a new splinded bottom bracket and Race Face Prodigy xc cranks. I had them professionally {sic} installed but they've loosend several (4-5) times, even coming off. They've been checked and re-torqued a couple of times but it seems to keep happening. The shop is not being cooperative with regards to returning them, in the event that I'm just stuck with them, is there any fix?
