The RR40 is in no way inferior to the RX40. It’s extremely light, extremely stiff and has, of course, also been aerodynamically optimized by Len Imes, an expert in computational fluid dynamics (CFD) from iXent in Munich and former professor at Stevens Institute of Technology. You can even take a few little off-road trips with this road bike rim. Handmade in Germany.

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. For our RR40 rims are only tires for hookless rims allowed – manufactured by Schwalbe (Schwalbe Pro One)
