Avian Versus Youth Carbon BMX Fork-20"X1"-Stealth Black Evo

The Avian Versus Carbon BMX Fork in Stealth Black Evo is Avian's flagship race fork, offered in six configurations that cover every BMX class. Toray carbon legs meet an integrated M10 locking system that preloads the headset and locks the stem with a 5mm Allen key, with nothing pressed into or clamped around the steerer.
