With hollow axles that make conversion to quick release super easy, the bolt-on Surly Ultra New hub is a nice upgrade for your daily ride.

  • Features

    • Ultra New hub comes with fixing bolts, but is quick-release–compatible without axle conversion
    • Made with 6061-T6 forged and machined aluminum alloy with medium-height flanges
    • Axle is made of chromoly steel, while the fixing bolts are high-grade stainless steel for corrosion resistance, high strength and good looks
    • Fixing bolts tighten and loosen with a 6 mm hex wrench
    • Bolt caps and 'cone' nuts are also stainless steel, and are heavily knurled for good bite, reducing the chance for your wheel to slip in the frame under high load
    • Cones and dust caps interlock to maintain axle stiffness
    • Axle/cone system uses a specific shouldered axle that allows the hub to be completely adjustment-free and simple to service
    • Ultra New hub spins on non-adjustable 6901 model bearings
    • Stainless 6 mm bolts are included; quick-release skewer is not included
