Super-light and super-stiff for crazy acceleration. You’ll love every turn of your pedals. The new geometry with modern inner width is optimized for 25mm wide tires and the laminate is designed for maximum stiffness. This has made the rim the embodiment of pure speed on the road.

Len Imes, an expert in computational fluid dynamics (CFD) from iXent in Munich and former professor at Stevens Institute of Technology, has subjected our RX40 rim profile to aerodynamic analysis and optimized it using CFD for minimum air resistance in various riding scenarios.

We meticulously spoke our wheels by hand.

This wheel set comes with DT Swiss 240 hubs and you can chose from Shimano or SRAM body. It is unused, but has little imperfections in the coating that do not affect the performance or stability. Weight: 1456gr.
