The K-Force Light BB392 EVO Modular pushes material technology to the limit to create a hugely strong yet light carbon crank. This modular 2x direct mount construction means no weight is wasted on unused mounts that would only fill up with dirt. Even the Torx-headed chainring bolts are lightweight aluminium, while the ABS system - Asymmetric Bolt Spacing - puts extra strength behind the crank arm, right where it is needed. The result is a very stiff, light crank: it's just 560g.
The chainrings are CNC machined from aircraft-grade 7075 aluminium, and ramped and pinned for optimum shift performance.
The redesigned, unidirectional carbon fiber arms are hollow for maximum strength and minimum weight. The drive side flows smoothly into the chainring spider as one extremely stiff piece, and there it bonds to a 30mm forged aluminum spindle that is tough enough to take anything the trail throws at it.
The BB392 EVO axle sizing is highly versatile, and needs only simple adaptors to fit BB30, Press Fit, Press Fit 30 and English Threaded bottom brackets. It is ideal for riders wanting to take their upgrades with them to future frames.
