Right. I'm fitting a 10spd XTR F mech (and XTR shifter) on to a bike with a X0 double chainset. It won't change up. I've check H/L screws and they are not making contact with the stopper. When I release the cable and manually push the mech it full extends and changes up with no problem but the range of movement of the mech when using the shifter does not seem to be sufficient to get the chain on the large chainring.
If I unscrew the barrel adjuster all the way it will just about get up, but that shouldn't be necessary. I have fitted scores of front mechs so don't get it. Could this happen if the mech is a 2 or 3mm too high? Is an XTR F mech not compatible with a SRAM doubt crankset?
Any ideas greatly appreciated. The wife will be home in an hour and that means I will have to clear the work stand and tools off the sofa and the hearth rug.
Cheers
SBD
