2013 seems to be shaping up to be the year of the disc for road and cross alike. As to not be left behind, Rolf Prima has announced two new road models that accept those lovely rotors we all keep gravitating towards.
Up first we have the new Vigor Alpha wheel. Cheat the wind with this 33mm deep, 22mm wide aero rim profile. The wheels come in at 1640g per pair. Holding the hub on are 20F/ 20R bladed spokes. And speaking of hubs, Rolf is using their XST+ disc specific hub. More on those…
Proprietary hubs, designed in the USA. Rear hub features our Patented Differential Flange Diameter, which effectively doubles the number of pulling spokes and creates a more durable wheel. Black, CNC machined, hub shells with alloy front/steel rear axles with sealed cartridge bearings provide strength, stiffness and reliability. Both hubs are compatible with disc brakes. Freehub: CNC machined titanium, electroless-nickel plated freehub body has 3 independently sprung steel.

Sometimes, lighter is better. With that in mind, Rolf Prima brings us the Elan Alpha road disc wheel set. The Elan Alpha uses the same XST+ hubs and spokes as the Vigor Alpha, but runs a more shallow, 23mm x 22m rim. Despite using a 23mm rim, Rolf Prima places this wheel into the aerodynamic category. Weight comes in at 1445g for the set. And given that the weight gain over the non-disc Elan wheelset (1315g) is in the hub, these should spin up quick and climb nicely.
Both wheelsets feature a machines rim braking surface as well. Also, both are Shimano/SRAM 10/11 speed or Campagnolo 10/11 speed compatible.
