Well the frame that was ordered and delivered has a BB30 bottom bracket. Think I didn't do my homework too well when pulling the trigger on the BB type, its a minefield out there. For the past week I've been mulling over the options...
XX1 crank - Pro's made for the job, Con's expensive chain rings as 120 BCD essentially non standard.
XT/XTR 2x10 configured as 1x10 - Pro's 104 BCD pretty much the standard, plenty of choice for chain rings, Con's requires a BB30 to 24mm convertor (like this), why add more weight and another point of failure.
SRAM X9 with removable Spider - Pro's max weight saving, somewhere in the region 150gms can be shed by removing the spider existing chain rings and adding a spiderless chain ring, Con's costly chain rings as they are only made by a few companies (MRP, AbsoluteBlack and NSB).
Of the 3 spiderless chain rings, only the AbsoluteBlack doesn't necessarily require a Type2 rear mech as it's a Wide/Narrow chain ring.
Trigger pulled this morning after a lot of deliberation, got a new SRAM X9 26/39 crankset for £50 (incl postage) off EBay. And I've my eye on a MRP Bling Ring, if that doesn't pan out I'll get a AbsoluteBlack 32T spiderless chain ring like below (only in black!!)
