The Box Four BMX Crankset delivers a strong and reliable 2-piece crank design for BMX racing. Featuring an oversized 24mm spindle pressed directly into the drive-side crank arm, the Box Four crankset offers excellent durability, stiffness, and easy installation.
The non-drive-side crank arm uses a 2-bolt pinch system for a secure connection, while the unique 4-bolt 104 BCD spider incorporates a flex-resistant reinforcement ring for improved stiffness and efficient power transfer.
Steel pedal inserts provide additional durability at the pedal threads. The crankset includes the required pedal washers and an external sealed-bearing BSA bottom bracket, making it ready for installation.
