Anyone had problems with their X9 rear mech. I've just fitted a brand new 2010 one from CRC which stopped shifting into the smallest 2 or 3 sprockets intermittently on its first ride yesterday.
I thought at first it was the cable but I've taken it off and it's just too stiff for the return spring to actuate fully - it won't drop into the highest three gears at all with the bike on the stand. It didn't get clipped on anything and is perfectly straight and unmarked.
Had XTR for years on the bike but one of the shifters was on the blink and I couldn't get them set up for one finger braking - but, never ever had a problem with the mech. Not happy.
