So my LH (xtr 970) shifter wouldn't drop the chain cleanly to the granny today. Seemed to be dropping the mech to the low stop though.
When I got back, after cleaning the bike popped it in the workstand & took a quarter turn off the Low stop & that seemed to do the trick.
Was testing changing up & down through the triple OK when it just stopped changing down. At all. Chain is on the big ring and the shifter lever seems to move freely but with no resistance and no effect.
So before I operate, will springs fly off in all directions? Has anyone seen a guide or is it relatively easy to dismantle & reassemble.
