Have a set of XT 770 9spd shifters with 2 way release on the upper lever. Last couple of rides the upper lever trigger has been 'failing' about 50% of the time when pulling the trigger. Still works great when pushing it but just wondering whether it's worth opening it up and taking a look.
Any clues or tips on what's next?
