Chris King R45 142x12 Rear Hub (Centerlock, Shimano/SRAM Compatible)

Built with precision, performance, and longevity in mind, the Chris King R45 142x12 Rear Hub is engineered for road disc and gravel bikes. Combining lightweight design with legendary in-house bearings and Centerlock rotor compatibility, the R45 hub offers superior rolling efficiency, durability, and that unmistakable “angry-bee” Chris King sound.

The patented RingDrive™ system delivers 45 points of simultaneous engagement, ensuring lightning-fast power transfer, improved traction, and virtually drag-free performance. Bearings, available in steel or ceramic, feature heat-treated, surgical-grade steel races machined simultaneously for perfectly matched inner and outer races. With proper maintenance, these hubs burnish over time, becoming faster and smoother with every ride.

The R45 is fully serviceable and rebuildable with the Chris King R45 Hub Service Tool, allowing riders to maintain peak performance for years. Available in 24h, 28h, and 32h, and compatible with Shimano/SRAM HG or SRAM XDR drive shells, this hub is the ultimate choice for high-performance road and gravel builds.
