I am having an intermitent shifting problem that is driving me up the wall
About 30 % of the time when i shift into the small chainring the rear gears start jumping as if it wants to change to another gear , a slight push to the left on the rear shifter settles it down.I have checked chain wear and its less than 75 % just in case, the front chainring is worn but not hooked .
The bike is maybe 3 years old and had a new rear mech in the last year although i have fiddled with the indexing it is never crisp through the whole range so i was wondering if the cable needs replacing but i am unsure as i would have thought that cable tension would not change as the spring takes up the slack?
