XTR M970a right shifter issue

[jeroenjanssen]

Hi all,

I recently picked up a pair of nice xtr m970a rapidfire shifters; they should be 3x9.

I havent fitted them to bike yet, but i noticed that the right shifter only does 6 clicks (so 7 gear changes). As I'm no expert at this, does anyone know what can be the issue? Can this be adjusted to 7 - 8 - 9 speed?

Or maybe there is no issue and I just need to put it on a bike to try it?

Thanks,
Jeroen

Re:

Sounds like an issue, you can't adjust them in that way. Should click through off the bike. Spray some gt85 or similar in them as the grease may have dried up or got gunky and is preventing the pawls from engaging properly.

It's not clear whether you've tried feeding some cable through and putting it under some tension - as if it were fully built up onto the bike. You might find that the cable's tension frees up the missing gears. ishaw's GT85 suggestion would still be worth trying either way!

Havent fitted a cable yet but will try that first!

Thank you both!
