Surly new ultra rear mountain hubs 135mm OLD

£70.00


Surly Ultra New hubs use a 6061 T6 forged and machined aluminum alloy with medium-height flanges. What's Ultra New about these hubs are their guts.

The Surly Ultra New hubs use hollow axles mated to thread in wheel fixing bolts, 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 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, 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, we 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.
