*SURLY* ultra new disc rear hub (black)

A rear hub for disc brakes from the American brand “Surly”, which produces high quality bicycles and parts that are fun to ride, durable, and affordable.

The previously released New Hub has been renewed from the nut or QR specification to the bolt-on specification without changing the hub shell.

The center axle is made of highly rigid chromoly, and the fixing bolts, bolt caps, and cone nuts are made of rust-resistant stainless steel.

The 135mm wide rear model is available in freewheel and fixed gear versions for single speed use.
