Full Speed Ahead FSA Afterburner Modular Double 392EVO V19 Mountain Bicycle Crankset - CKM-OS9183CS/92 (22/36T - 175mm BB392)

The 11-speed Afterburner has been completely redesigned for its highest performance yet with lighter crank arms, a smaller spider and AL7050 chainrings. The svelte new arms are hollow-forged from tough aluminum and clamp to a 24mm or 30mm chromoly axle for the ultimate rough-trail strength. The chainring bolts are also chromoly, while a clever design of the non-driveside arm eliminates the weak point of a pinchbolt. It's available in 170mm and 175mm lengths. The chainring is CNC-machined from hard-wearing 7075 aluminium, and the whole crank is optimised for 11-speed drivetrains. The Megatooth chainrings ensure amazing security thanks to an ultra-deep profile and Narrow-Wide spacing that lock the chain on, and gearing ranges in two-tooth increments from 26T to a huge 38T. Overall weight is a paltry 716g. The sandblasted matte finish combines with polished highlights and sections of beautiful aluminum to exude a monolithic energy that belies its low weight. Subtle logos only enhance the look while laser etching means the graphics last too, no matter what the weather throws at them. BB392EVO Campatible
