No other Airborne bike echoes our Born from BMX mantra more than the Cro-Hawk DJ 26 (26-inch wheel dirt jumper).

Together the Cro-Hawk flies straight, flips, or spins, always providing confidence for the most demanding leaps and feats. Double butted top and down tubes help keep the bike light while providing strength where you need it. The 4130 chromoly frame is matched with a custom configured RST Dirt suspension fork with 80mm-travel. The stiffer setup steers you in the right direction while still providing needed relief upon impact. Let the Cro-Hawk show you why 4130 is more than just most every BMX’ers ATM pin. It’s the most trusted metal for going big on dirt, plywood, and concrete.
