Box Three hollow-forged crankset

The Box Three crankset features a two-piece forged hollow design with an oversized bottom bracket interface. The 24mm axle is pressed into the drive-side crank arm for durability and easy installation. The non-drive side crank arm features a 2-bolt clamping system for added strength. Our unique 104 BCD 4-bolt spider features a flex-resistant ring for optimal performance.

Box Three cranksets include steel pedal inserts that require pedal washers and external sealed BSA bottom brackets, both supplied in the box.
