My Boss has a Cannondale with 11 speed sram Apex. It never shifted properly, always had tendency to miss a gear then jump 2 sprockets.
Recently it got unrideable.
After a lot of faffing about I measured single click cable pulls.
From 3.5 to 4.5 mm per click!!!
Derailleur has play in all pins, even with new shifter it would not shift properly.
All that wear after 3 years and under 2000miles, most of them on direct drive turbotrainer.
Swapped for deore xt m8000 shifter and derailleur, whole operation did cost less than sram force shifter(£140) and took 30 minutes, should be good for next 10000miles.
