The BOX Three crankset delivers lightweight performance inspired by premium M35 and M30 designs. Oversized hollow forged aluminum 6061-T6 crank arms reduce weight while maximizing torque stiffness during hard pedaling. A robust 24mm Chromoly axle and CNC-machined aluminum spider ensure durability and precision, while the bending-resistant star design maintains optimal performance under load.
Built for reliability with Chromoly pedal inserts and a 4-bolt 104mm BCD mount, this 2-piece crankset weighs just 904g at 177.5mm length. The 44.5mm chain line provides excellent clearance and compatibility with modern drivetrain standards.
Includes a Euro BSC/BSA bottom bracket. Also compatible with Press Fit 86mm systems featuring a 24mm axle. Ideal for riders seeking a balance of strength, efficiency, and reduced rotating mass.
