They use hollow axles of our own design mated to threading wheel fixing bolts, as opposed to the nutted axles of our previous hubs. This makes conversion to quick release super easy. All Ultra New hubs come with fixing bolts, and they are QR compatible without axle conversion.

The axles are made of CroMoly steel, while the fixing bolts are 10.9 stainless steel for corrosion resistance, high strength, and good looks. 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 heavy loads.
