Road Wheelset RR40

Lightweight with a unique look and still uncompromisingly sturdy and robust.

Len Imes, an expert in computational fluid dynamics (CFD) and former professor at Stevens Institute of Technology, has subjected our rim profile to aerodynamic analysis and optimized it using CFD for minimum air resistance in various riding scenarios. This has made the rim the embodiment of pure speed on the road. Imes drew on his extensive experience as Head of Aerodynamics for the BMW Oracle Team (35th America’s Cup) and the INEOS Team UK (36th America’s Cup).

The rim is handmade in Dresden. Our Solid Edge Design (2.8 mm rim flange width) and Framed Edge (circumferential layup on rim flange) give us a very sturdy rim flange that provides protection from delami­nation and can withstand heavy impacts. The rim is fitted with internal brass spoke nipples. We use small spoke holes drilled at an angle (slanted spoke holes) to ensure that the spokes do not bend when lacing the wheel. This results in optimum spoke tension and a perfect wheel lacing process.

Another reason we use this technique is to provide a clean look. This accentuates the low weight and aero­dynamic shape.
