The SRAM X9 rear derailleur I have on my Meta 5 keeps sticking on my 34T sprocket on the cassette and won't change back down again without a small nudge.
I can let the tension off the cable but the parallellogram sticks and will not change down again until I have tapped it with my foot/hand.
Once off the 34T sprocket it seems to work fine the whole way back down to the 11T sprocket.
It is almost as though the spring in the parrallelogram is not strong enough to change its shape when at maximum extension.
I have done everything I can think of; I have GT85ed and lubed up the joints in the mechanism (I am unable to take it apart to give it a proper clean due to the nature of the construction) cleaned and lubed the newly changed cable and housing.
I am just wondering if I have missed anything or whether anyone else has had this problem with their X9. Advice please.
By the way the rear derailleur came with the bike and is 14 months old and has had very little abuse and the bike has been hardly used in the last 6 months.
