Hi my rear mech, XT 9 speed, suddenly stopped shifting mid-ride to the last 3 cogs on the cassette (i.e. 11, 12, 14) with the lever just going floppy once I get into the last cog I can select. Cable looks OK, decent tension, mech hanger/mech look straight and nothing changed (by me), no big impacts etc during the ride.
Not sure where to start other than strip it down and reset up. I’m thinking the shifter might be dead if it can’t get the last 3 gears? Replacement shifter is ~£30 so not huge cost but don’t want to chuck a shifter away if I don’t need to.
Has anyone had anything similar and got any possible solutions?
