Super-light and super-stiff for crazy acceleration. You’ll love every turn of your pedals. 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. This has made the rim the embodiment of pure speed on the road.

The wheel set was used for 3 month. It is in great condition with only very few wear marks. The wheel set gets serviced before we send it your way.
