Each Rolf Prima wheel orbits around a proprietary new hub designed and manufactured in the USA. Patented Differential Flange Diameter™ on the rear hub lends a mechanical advantage effectively doubling the number of functional pulling spokes; increasing wheel durability. CNC machined hub shells with oversized axles provide high strength, stiffness and light weight. Optimized flange contours provide full spoke elbow support, increasing spoke life. Precision cartridge bearings feature preload adjustability on both front and rear hubs and spec low drag supplementary contact seals.
