XTR Crankset (1x, 2x, 3x)
There are a couple of crankset options available to you if you're building an XTR Di2 bike. Which crankset you choose depends on your front derailleur (or lack thereof), your frame and the style of riding you do.
The triple crankset weighs 656g, the double crankset 629g and the single comes in at 604g (30T).
By far the simplest in terms of choices is the triple crankset, the FC-M9020-3. This Hollowtech II crankset comes with 40-30-22T chainrings and it is meant to be used with regular 142 mm O.L.D. frames/hubs.
Its P.C.D. is 96/64 and the chain line is 50mm.
There are three options when it comes to the double crankset. You've got the FC-M9000-2 for XC racing, the FC-M9020-2 for Enduro/Trail and the FC-M9020-B2 for Enduro/Trail with a 3mm outboard chain line (for O.L.D. 148mm / boost).
The Q-factor is 168mm (mtb standard Q-factor)
