Chris King R45 Disc Rear Hub

The R45 Disc is currently the one of the lightest and well-built Cyclocross and light-duty XC disc hubs you can purchase. It's design is virtually identical to the R45 road hub with the addition of the ISO disc mount, taller flanges and a larger axle.

The R45 Disc is insanely light without compromising build quality or durability to get there. This is due to Chris King's sensibility when it comes to designing a product. Weight loss is achieved through a cleverly designed hub mechanism that is primarily machined out of alloy to incredibly tight tolerances.

Beyond low weight, the hub functions flawlessly and is completely serviceable and adjustable. The low friction bearing seals allow the hub to spin without drag while the titanium 45-tooth engagement drive provides almost instant engagement. The one-piece alloy axle provides plenty of strength and stiffness. These Chris King R45 Disc rear hubs are compatible with all Shimano and SRAM 8, 9, 10 and 11 speed drivetrains.
