RR40

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)

RX and RR Rims Series – Realized in cooperation with iXent 

iXent GmbH is an internationally respected and requested development company that focuses on the development of lightweight structures through various industries and is based in Munich. The focus of iXent’s work is on applied lightweight construction and, in particular, on the structural design and manufacture of fiber composite components and systems.

iXent is well established in the development of lightweight high performance structures in the international sailing scene as well as in other racing sports such as automotive, bobsledding and many more.

One of the highlights in iXent’s achievements were the AC33 and AC34 America’s Cup wins of Oracle Team USA, where CEOs Christoph Erbelding and Thomas Hahn had a significant influence on the development as core members of the team.

Aerodynamics and hydrodynamics is their youngest and at the same time oldest passion. Working in the America’s Cup, they had a significant influence on the innovative foiling systems in AC34 and AC35. Working with Hal Younggreen and Len Imas, leading experts in computational fluid dynamics, gave them the idea to reactivate their knowledge of aero- and hydrodynamics. Managing Director Thomas Hahn worked during his studies with Richard Eppler, one of the most famous German aerodynamicists and known for his designs of airplane wing profiles. Thus, airfoil development was the natural start for iXent and so they consequently expanded into CFD.

An example of this commitment is the Daytona DOS, which is designed to be the fastest Hydrofoil on the market. With the profile series developed by Leopold Fricke (FLIX), the foil not only achieves this claim, it is also one of the few HydroFoils IKA-registered for the Olympic Games in the 2020/2024 cycle.

For Beast Components, iXent develops the aerodynamic design of the entire RX and RR rim series.
