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 Delta Rim Technology™: In skydiving, the Delta track is the fastest position for gaining forward airspeed. So, Rolf Prima mirrored this observation and adapted it for their Delta profile, which takes that cue using increased width and sidewall shaping to improve airflow and stability in straight on and crosswind situations. This wider rim is not just faster, but the additional tyre support improves cornering and handling in all riding conditions Buy Rolf Prima Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
