Box Four 2-piece crankset

The Box Four crankset features a two-piece design with an oversized bottom bracket interface. Its 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. Its unique 104 BCD 4-bolt spider features a flex-resistant ring for optimal performance.

The Box Four crankset features steel pedal inserts that require pedal washers and external sealed BSA bottom brackets, both supplied.
