Dont stress too much, chain falls out of 42t on back pedal with the complete XT drive including cranks too! Pitty, only flaw so far.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.

Mmmmhhh... Hope T-Rex sometimes does the same. Not a problem for just backpedaling to clock the cranks, but if you give it like one or two revolutions, sometimes it does it.Dont stress too much, chain falls out of 42t on back pedal with the complete XT drive including cranks too!

SRAM XO1 11-42 does it too.Gee I had this problem on the Trance from 11-36 cassette, haha.

I wouldn't do two turns ever while riding, but your second line is absolutely spot on! On a climb to suddenly clear the pedals over a ledge or rock I may need to back pedal usually not more than 90 degrees. The issue is if I do this rapidly, which is what will happen if I am trying to maintain momentum, the chain will drop a few cogs, then put the power down, crunching sounds and potentially snapped chain.Why would you NEED to back pedal several revolutions?
If it's falling off while navigating technical stuff with 1/4 turns then that sucks because you're headed to Tingly Fig town
Hahahaha I went to order that cassette from MTB Direct and it sold out whilst it was in my cart. I got mine from TBSM instead it also arrived today.My gear arrived from MTB Direct today... man that 11-42 cassette is huge!
I've never had a shifter with a gear indicator before... does it just come off by removing the screw?
Also with the chain, as a reminder... does it go like this:
Compress shock fully, wrap around front ring, wrap around largest rear cog, not through derailleur, and add 2 full links?
I plan to bump the front from 32t to 34t in the next few weeks, will the same length chain be fine?
Supposedly yesCompress shock fully, wrap around front ring, wrap around largest rear cog, not through derailleur, and add 2 full links?
NO. You're better off waiting until you have the 34tI plan to bump the front from 32t to 34t in the next few weeks, will the same length chain be fine?
Yes.One question is will the new cranks fit existing xt/xtr bottom brackets ??
You could, but a better option is to chuck it on the small sprocket & pull sufficient tension so there's about a finger thickness clearance between the top jockey wheel & the lower span of chain (in this gear the derailleur cage sits basically horizontal). Given this method ensures sufficient length for multiple chainrings, it will allow you to play with chainring sizes and have enough to allow for suspension influence too.Supposedly yesAlso with the chain, as a reminder... does it go like this:

I think so, there should be a cover plate provided to replace the indicator pod too.My gear arrived from MTB Direct today... man that 11-42 cassette is huge!

I didn't get a cover plate and it didn't look like you could remove the window to me. I hate it.... makes me look like a numpty (even more so). I will replace it with an I-Spec as soon as they are available though.I think so, there should be a cover plate provided to replace the indicator pod too.
