Details
The Box Four Crankset features a 2-piece design with an oversized bottom bracket interface. The 24mm spindle is pressed into the drive-side crank arm for durability and easy installation. The non-drive side crank arm features a 2-bolt pinch system for added strength. Our unique 4-bolt 104 BCD spider features a flex-resistant ring for optimum performance.
Box Four Cranks feature steel pedal inserts that require pedal washers and external sealed bearing BSA bottom brackets, and both are provided in the box.
