I ride a Swarf
XX1 crank chainline (found the answer :))
EDIT: Must be third time lucky....found the answer here http://cdn.sram.com/cdn/farfuture/Yp...ifications.pdf
I have searched and googled but no luck.
What is the chain line of the XX1 crank?

Reason: third time lucky...found my answer
What exactly is a rigid hard tail?
The link above is dead, but I found the answer.
I know someone will find this useful someday, so here it is...
XX1 Chain line direct from SRAM
Chain line is 49mm for the chain ring on the XX1 crankset. The closest aftermarket chain ring to the sram's chain line is Absolute Black, which is also at 49mm. Wolf Tooth Components is 50mm, and MRP Bling Ring is 51mm.
Hope that helps someone.
No the AB chain line is not 49mm is a little father out vs the xx1 complete setup.
Interesting find. I took the 49mm from their website. I wonder if they're mistaken.
Thanks for posting that photo
Fund this one by accident.
49mm is true in 98% of cases as you can move 2mm bb spacer from one side to another(or other parts) in cranks like X9, X0, S2200 and so on. Remember that this ring is not only for XX1 cranks and there are soo many different bb types these days.
the only setup we found which cannot be adjusted is PF92 by now as far as i know, but even then chainline is still respectable 50-51mm (this is a norm in Shimano cranks)
Currently running a 46T chainring with XX1 (BCD104 triple crank with XX1, 29er setup for urban/road)
the best I can get is 51mm chainline (standard middle ring)
any less the chainring will hit the side of the chainstay (the chainstays on MTB are wide to accept up to a 2.5" tire)
but with a smaller chainring you can get more room run much better chainline without the chainring contacting the chainstay. But you can only move your cranks a few mm with the BB adjustment
I would suggest a 45mm chainline is much better for XX1 this puts the chainline closer to the centre of the rear XX1 cluster (6th gear) which means far less cross chaining in first gear.
You can get a 45mm chainline by running a 80BCD chainring on a 120/80 crank
or using BCD64 chainring on a 104/64 crank.
Other brand chain rings should work fine with the XX1 11speed chain
