Ultra New hubs look much like their predecessors. In fact, the hub shells have not changed at all. They remain 6061 T6 forged and machined aluminum alloy with medium-height flanges. What's Ultra New about these hubs are their guts.

Ultra New hubs use hollow axles of Surly's own design mated to thread in wheel fixing bolts, as opposed to the nutted axles of Surly's previous hubs. Hollow axles make conversion to quick release super easy (remove bolts, insert QR skewer, install wheel into frame or fork, ride). All Ultra New hubs come with fixing bolts, but all are QR compatible without axle converson or any other bits. Neato. The axles are made of CroMoly steel, while the fixing bolts are 10.9 stainless steel (i.e. high grade) for corrosion resistance, high strength, and good looks, and the bolts tighten and loosen with a 6mm 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. The cones and dust caps interlock to maintain axle stiffness. Ultra New hubs spin on non-adjustable 6901 model bearings. Throw your wheel on the bike, tighten the bolts and ride.

One other thing you might like to know: All the Ultra New hardware will retrofit to New hubs. That is, Surly sell kits to completely transform your old New hubs into Ultra New hubs, complete with new axle, bolts, bearings and the rest of the Ultra New hardware. Find the right kit for your New hub, install, and go.

Is this a freewheel hub?

Yes, however only for single speed freewheels.
Lacing Surly Ultra New Hub?
18 Apr 2017
I was wondering if you would be prepared to lace a wheel with the Ultra New Single Speed Surly Hub (and Mavic XM117 26" rim)? If so how much would you charge for the complete wheel?

We can build the wheel. If you add your wanted items into your basket and then find the wheel build section of the webpage it will give you a total price.
