Crank arms, spider and chainrings the Afterburner has been completely redesigned for higher performance than ever. Those svelte new arms are hollow-forged from tough aluminum and clamp to a 24mm or 30mm chromoly spindle for the ultimate rough-trail strength. Chainring bolts are also chromoly, while clever design of the non-driveside arm eliminates the weak point of a pinchbolt. The outer chainring is CNC-machined from hard-wearing 7075 aluminum, while the middle and inner are stamped from the same lightweight material.
