Installed the new XT a few weeks ago, quite happy with it all in all, having the extra cog smooths of the ratio quite nicely.
Having some issues with the the chain falling off the big cog when back pedalling, if if do 2+ revolutions the chain will fall all the the off the 11t and jam into the frame.
Took a spacer out which made the chainline a little better, the chain will still fallout the 42t, but not nearly as bad. But, now under power the crank will hit the stays, poop.
So I'll have to put the 2.5mm spacer back in to the bottom bracket to space the cranks out, but now chainline is going back to really shit, rather than just put up with it shit.
Had a googles, does anyone make a direct mount chainring with offset to space the chainlin further inwards? It if was a standard 104BCD i'd just throw some spacers in, not sure spacing a direct mount out would work.
This didn't happen on 10spd with a OneUp 42t, the gearing limits are correct and the shifting is snappy and fine.
Not back pedalling isn't an option on some climbs, as I need to clear cranks/pedals as the frame it low.
Edit: oops, cranks are racafeace cinch, as far as I can tell, sram rings with 6mm offset aren't compatable with racefaces direct mount cranks.
