The Box Three Expert Rear Hub-Black at J&R Bicycles is a slimmed down lighter version of the Pro hub that is perfect for smaller sized BMX riders. Made with a 4-pawl system with 120 points of engagement and precision sealed bearings, the Expert Disc Rear Hub offers rapid engagement for super speedy power gain. To maintain the lightweight design, Box made this hub with aluminum alloy axles, reduced hubshell size and lighter hardware and polished it off with laser-etched graphics. Steel bolts, lockring and spacers come included.
