Marc Willers Caroline Buchanan Kurt Pickard the Dutch National BMX team and many other of the world’s top elite and amateur racers have been winning on BOX 20-millimeter freewheel hubs so there’s no longer any reason to think freewheels suck. With a quality freewheel you’ll get thousands of skip-free starts sprints and laps something very few hub makers can guarantee. And there are other advantages: freewheel hubs cost less weigh less and most important work with 20-millimeter axles without any compromises. Hollow Hubs feature cold forged and CNC-machined 6061-T6 aluminum shells fitted with precision sealed bearings and 20-millimeter 7075-aluminum axles and axle nuts. Besides 100- front and 110-millimeter rear spacing they also feature oversize 32-millimeter dropout interface washers which further increase the stiffness of the wheels.
