Box One Carbon 20x1-1/8” 28H Rim


Box One Carbon BMX Hoops exploit a medium height profile and wide internal dimensions to create a high performing, stiff carbon rim. Due to their compatibility with both tubeless and tubed configurations, these rims have a broad range of tire options and setup possibilities making them perfect for any track. Available in 28-hole 20 x 1-1/8-inch with and without brake-tracks. PLEASE NOTE: Box One Carbon BMX Hoops with brake tracks require Carbon Brake Pad Inserts and CANNOT be used with standard Brake Pads made for aluminum Rims.
