The Box Four Crankset is a high-durability 2-piece system designed to anchor your BMX race build with exceptional stiffness. By utilizing a cold-forged 6061-T6 aluminum construction, this set provides an oversized bottom bracket interface that stabilizes your frame under heavy torque. The 24mm Chromoly spindle is precision-pressed into the drive-side arm, offering the reliability of a pro-tier fork and ensuring your pedal power is efficiently transferred to the rear hub.

Engineered for the rigors of the track, the non-drive side features a dual pinch-bolt system for secure clamping force, while the 104 BCD spider is reinforced with a flex-resistant ring to maintain chain alignment. This setup is built to handle explosive starting gate snaps, supporting riders up to 115kg. Whether you are leaning into tires through a berm or pulling on the handlebars during a sprint, the Box Four delivers consistent bike control.
