The Box Five is a precision-engineered BMX race component utilizing the reliable JIS square taper standard to anchor your frame. Featuring an oversized bottom bracket interface with a unique step-down shape, these arms are individually designed for each length to ensure maximum pedal boss strength. Cold-forged from 6061-T6 aluminum, they provide a rigid platform that mirrors the durability of a pro fork while maintaining an ultralight profile for younger racers.

With a 5-bolt 110 BCD pattern, this crankset integrates seamlessly with your chainring and chain for consistent power delivery. Designed for versatility, they are compatible with all BSA European square taper spindles, allowing you to fine-tune your bike ergonomics. Whether gripping the handlebars at the starting gate or carving berms on 20-inch tires, the Box Five ensures a responsive and stable ride.
