The Box One Fork Adapter Set (20mm to 10mm) in Black allows riders to use standard 10mm (3/8") male front axle wheels inside a high-performance BMX fork designed for oversized 20mm thru-axles. These adapters act as a precise reduction shim, saving you from the expense of purchasing a brand-new front wheel or hub when upgrading to a stiffer 20mm race fork.
