The Surly Ultra New Rear Hub is an upgrade to the original New hub, featuring a hollow axle design for easy quick-release conversion and high-strength stainless steel hardware. With its maintenance-free 6901 bearings, precision-machined 6061-T6 forged aluminum shell, and aggressive knurling on cones and bolt caps, this hub is built for durability, reliability, and performance on the road or track.
