This is the Rolf 2013 Elan Alpha 700C Clincher Road Wheelset. The best of both worlds – light weight and durable. The Elan Alpha is built on our Delta rim technology. The Delta rim design not only improves stiffness and handling, but it allows Rolf to shed even more weight off an already industry leading lightweight wheel set. Even more impressively, the Delta technology in the Elan Alpha improves aerodynamics to the point that this wheel set has moved fully into the aerodynamic wheel category. Light, aerodynamic and hand-built in Eugene, Oregon.
Paired spoking is when the spokes meet at the rim in pairs. In conventional wheels the spokes are evenly spaced. Tensioned spokes pull not only down toward the hub, but also outward toward the flanges. When spokes are paired at the rim, these left and right pulling forces are neutralized. Pairing the spokes allows Rolf to use fewer spokes on lighter rims than anyone. The Delta Rim Technology is a shaped profile that improves tire fit, creating a more aerodynamic interface with the tire as well as better tire support. Our wider tire bed fits tightly to the tire sidewalls smoothing airflow and better supporting the tire sidewalls. This improves turning precision, ride comfort and overall handling. Rolf Prima’s Differential Flange Diameter technology transmits drive torque in the rear wheel across both flanges to increase the number of pulling spokes. This means even with Rolf Prima’s low spoke counts, you still have the same number of pulling spokes as a traditional spoked wheel. Rolf Prima’s Dish Reducing Design reduces the dish of the drive side spokes, increasing stiffness and making for a more stable and smoother ride. Dish Reducing Design technology is used on all Rolf Prima wheel models.
