The Pro Hub is made with a 6061-T6 aluminium hubshell paired with a chromoly steel 10mm axle for strength and durability. It also features a super-fast 120 tooth engagement system, precision sealed bearings and a 6-bolt disc brake rotor mount, all creating a hub that accelerates and decelerates insanely fast.
