Lewis ALU Cranks: All-In on DH Strength Without the Weight Penalty

The hollow-out design sheds grams without sacrificing stiffness, and the rigid anodized finish shrugs off rock strikes, pedal chunder, and season after season of bike park laps.
Whether you're smashing through rock gardens at warp speed or charging steep tech in the backcountry, the ALU cranks deliver consistent power transfer with bombproof reliability. These aren't your average trail cranks — they’re purpose-built for gravity riders who demand maximum confidence underfoot.
