SURLY Ultra New Disc Hub Front

The SURLY Ultra New Hub is very much like the hub before it. The hub shell hasn't changed at all: it is machined from forged 6061-T6 aluminum, with mid-size flanges.

Thanks to SURLY's own design, the hub is bolt-on yet hollow inside, so you can also use a quick release. It converts between bolt-on and quick release without any extra parts.

The axle is chromoly steel, and the axle bolts are 10.9 stainless steel, chosen for corrosion resistance, strength and good looks. They tighten and loosen with a 6mm hex key, and being bolt-on also helps deter theft.

The bolt caps and "cone" nuts are rust-resistant stainless steel too, with serrated washers that bite firmly into the frame, making the wheel less likely to slip in the dropouts under heavy loads.

It spins on non-adjustable 6901 sealed bearings. A dedicated shouldered axle means no cone adjustment is needed, and servicing is simple.

*Stainless steel 6mm axle bolts are included. A quick release skewer is not included.
