So, i've had these shifters now about 2 years on various frames/configurations. They're 10 speed SLX dyna-sys.
Sadly, the rear 10 speed is getting a little sluggish now, heavy i guess is the best term i can think of.
I'm running full outer and have just installed a new inner which has helped a fraction, but not by THAT much. So i'm guessing the inner workings have got a bit tired and maybe even a bit rusted up.
Obviously taking a shifter apart ends in springs/disasters everywhere, so i'm avoiding that plan.
Anywhere i can squirt a bit of something and see if it loosens up a touch ?
