Marc Willers, Caroline Buchanan, Kurt Pickard, the Dutch National BMX team and many other of the worlds top elite and amateur racers have been winning on BOX 20-Millimeter Freewheel Hubs for more than two years, including a World Championship and three medals this year in New Zealand.
Their more reliable and weigh less than many cassette hubs and, most importantly, have 20-millimeter axles. Box's race-proven 20-mil axles help transmit more power from the pedals to the wheels, propelling the rider forward faster and straighter.
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 100mm front spacing, they also feature oversize, 32-millimeter, dropout interface washers, which further increase the stiffness of the wheels.
