Race Face Next SL G4 Cinch Crankarms

The Race Face Next SL G4 Cranks make improvements in both the lightness and stiffness departments compared to the previous iteration. A revised crank profile combined make these gains possible, as does the drilled-out spindle interface to further shave weight. Proprietary molding technology yields an extremely light crank with a totally hollow core, and the 30 mm spindle itself is CNC'd from a special aluminum alloy that is 20% stronger than standard 7050 alloy.

Aside from their featherweight status, the NEXT SL G4 Crankarms are also the model of versatility. They use Race Face's CINCH interface which accepts direct mount chainrings or removable spiders. The upshot of this is it can take advantage of any current BCD, or any future developments as well.

Claimed weight is 430 g (including 32T direct-mount chainring, sold separately). Bottom-bracket not included.
