Pls help - chain catching in RD cage...
the chain seems to be catching in the rear mech cage.
It happens much more in the smaller cogs and when I ride it feels like the chain is jumping - but it isn't changing cogs..
When I pedal with bike off ground to watch it - what happens is the chain seems to get caught for a second and the cage gets pulled forward a little - then it releases and hence it feels like the chain has jumped...
Anyone had this ? know what it is ?
I took the mech off my old bike & it worked fine on that -
the cable tension is set fine and the chain shifts fine - so it's not cable tension
