Hi all, wondered if anyone can help, was changing gear today and felt a faint snap/sheer noise, my gears don't work properly now and the chain has gone really slack when in the bottom cog on the back.
I can't see anything broken but when I took the mech off there was a small half round size black washer, looks like it's only half of what should be there? My question is does anyone else have this mech and if so is there some kind of tiny round torsion spring inside the bolt that screws in to the frame mech hanger?
Really hope this makes sense... Oh and if it helps the bolt just falls out the mech body hole where as others I see the bolt is solid and just spins round inside the mech body.
Omg I just gave myself a headache typing that!
Anyone have any ideas?
