Rolf Prima Elan Aero Road Wheel Set. The 24mm tall single cavity rim features a semi-aero rim profile with a narrow spoke bed to minimize weight. Elan rims weigh a mere 370 grams for 700c and 320 grams for the 650c version. Brushed sidewalls. 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.
