Bringing the spokes to the rim in pairs neutralises the left and right outward pulling forces, which allows them to build true wheels on lighter rims with fewer spokes. Fewer spokes and lighter rims help create increased aerodynamics and faster performing wheels Differential Flange Diameter™: Rolf Prima's patented oversize non-drive Differential Flange provides the leverage to transmit drive torque in the rear wheel to the non-drive spokes, thereby increasing the number of torque absorbing spokes Buy Rolf Prima Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
