The Box Three Crankset features a hollow-forged 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 Three Cranks feature steel pedal inserts that require pedal washers and externally sealed bearing BSA bottom brackets, both provided in the box.

      Can I use axle or bottom bracket spacers with these cranks?
      Can I use axle or bottom bracket spacers with these cranks? A. The cranks are designed specifically for 68mm wide BMX bottom bracket shells and require no spacers. Spacers may be required if your frame has a bottom bracket shell that is less than 68mm wide.

      Can I install my chainring on the outside of the spider?
      No. A chainring can only be installed on the inside of the spider.

      Can I ride with a loose pedal?
      No. A loose pedal will damage the crank and can cause injury. Always ensure that your pedals are tightened correctly.
