RX40

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.

Handmade in Germany.

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.

Tubeless Ready | Hooked Design | Disc Only | Aerodynamically Optimized

DESIGN & INNOVATION AWARD 2021 – WINNER

„The rims of the Beast RX40 wheelset are handcrafted in Dresden and paired to DT Swiss 240s Disc Center Lock hubs with 24 Sapim CX-Ray spokes – handcrafted meets proven quality. A concept with which Beast is able to produce a stiff, highend wheelset that is also quite light at 1329 g, despite the relatively high number of spokes. For aerodynamic reasons, the nipples are concealed inside the hookless carbon rim, which is fashionably wide with an inner rim width of 20 mm. Quick in acceleration, unaffected crosswinds and an absolute eye-catcher at the ice cream parlour! The RX40 wheelset doesn’t have a weight limit and is a premium upgrade for your bike, both technically and optically.“
Award Jury Verdict

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.
