Our single-ring K-Force Light Evo is the epitome of minimalist efficiency, and it’s optimised for the 11-speed systems that make single front-rings so successful. With unidirectional carbon arms and a slimline, purpose-designed spider, this very stiff crank weighs just 425g.
The redesigned carbon fiber arms are hollow for maximum strength and minimum weight, while alloy inserts hold pedals firm. Even the Torx-headed chainring bolts are lightweight aluminum, while our ABS system – Asymmetric Bolt Spacing – puts extra strength behind the crank arm, right where it’s needed. The chainring is CNC machined from aircraft-grade 7075 aluminum, and is available in either 36T, 34T, 32T or 30T sizes. With no need for front shifting, the ultra-deep Narrow-Wide teeth of the Megatooth design clamps chains tight over even the roughest ground.
BB392 Evo axle sizing is extremely versatile, and needs only simple adaptors to fit BB30, Press Fit, Press Fit 30 and English Threaded bottom brackets. It’s ideal for riders wanting to take their upgrades with them to future frames. It also means everyone gets the benefits of the big, 30mm hollow alloy axle – stiffness and power transfer are unmatched, and strength is high. It’s tough enough to take anything the trail throws at it.
The K-Force Light Compact Evo is available in 170mm and 175mm lengths.
