Surly Ultra New Disc Front Hub - QR x 100mm, 6-Bolt




Surly's Ultra New Hubs look similiar to their predecessors, in fact, the hub shells have not changed at all. They were designed using 6061-T6 forged and machined aluminum alloy with medium-height flanges, same as the previous versions.

What’s Ultra New about these Hubs are their guts. Ultra New hubs use hollow axles of Surly's own design mated to threadin wheel fixing bolts, as opposed to the nutted axles of previous hubs. Hollow axles make conversion to quick release super easy (remove bolts, insert QR skewer, install wheel into frame or fork, AND Ride).

All Ultra New Hubs come with fixing bolts, but all are QR compatible without axle conversion or any other extra crap. 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, good looks, and the bolts tighten/loosen with a 6mm hex wrench.

Bolt caps and 'cone’ nuts are also Stainless Steel, and heavily knurled for good bite, reducing the chance for wheel slippage under high load. The cones and dust caps interlock to maintain axle stiffness.

Ultra New Hubs spin on non-adjustable 6901 model bearings. Just throw your wheel on, tighten the bolts, AND Ride.

In addition, all the hardware will retrofit to New hubs. So you can buy a kit 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.
