Box One 507 BMX Race Rim-Front-36H-24x1.75"

The Box One 451 Rim-Front-28H-20x1 1/8" is as low-profile as it gets. All the better to be lightweight and speedy. Featuring double walled aluminum, eyeleted construction. Lacking a sidewall braking surface this rim is designed specifically for the front of the bike, but can be used on the rear if using a disc brake.

Please note: Box has not supplied photos of the front rim, so the pictures on this page are for the rear rim which has a flat surface for the brake pads. The front specced rim does not have this flat surface.
