The Box One X4 Pro Carbon BMX Race Fork-20"-1 1/8"-Black-10mm is built for precise steering and a stiff, responsive feel when speed matters most. Its oversized carbon construction shifts strength where it counts, while the 1 1/8" alloy steerer helps reduce flex under load. With 10mm dropouts and an internal butterfly reinforcement, itβs a solid front-end upgrade for riders who want control they can trust.
