Surly Ultra New Disc Front Hub

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
