Pairing up a shiny set of Surly’s ultra new flip/flop track hubs with a pair of H+Son’s critically acclaimed archetype rims was a dream for this retro looking modern wheelset.
Hubs: Surly Ultra New hubs use hollow axles mated to threadin wheel fixing bolts, as opposed to the nutted axles. Hollow axles make conversion to quick release super easy (remove bolts, insert QR skewer, install wheel into frame or fork, ride). 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 so no need to carry a 15mm spanner with you any more!
