With short crank arms, 165mm in this case, you don't actually have much choice. Essentially you've got Shimano and SRAM mid-tier options. Or Race Face.
SRAM X01 Eagle DUB chainset is rated for enduro and uses carbon arms with a structural foam core and the forged and machined, top-tier, X-Sync 2 chainring.
In terms of power to weight the Race Face Next SL G4 really is a superb – it’s also silly light, sensibly stiff and cheaper than other carbon cranks.
The Truvativ Descendant Carbon is a great first step on the carbon crank ladder; factor in £80 worth of chainring and, it’s actually more of a bargain.
Praxis has done an excellent job on the Praxis Works Lyft crank, it’s stiff, lightweight, top quality and it should stay that way too.
Offers fantastic performance and reliability and really does look stunning.
Stiff, reasonably light and cheap… just a shame the Praxis BB doesn't stand up to scrutiny - £239.96
Shimano’s new XT groupset promises better versatility than XTR at a fraction of the cost. What better way to test it than 10,000m of Alpine descending?
Not a bad crank, but it fails to stand out in a very competitive field - £295 (No chainring or BB)
Super light, incredibly stiff and compatible with nearly every set up imaginable - £429 (N0 BB)
Specced on everything from the Epic up to the Enduro, so it must be doing something right - £500 (No chainring)
