Beast Components RR40 Carbon Disc | Clincher | Rim - 20-622 - 24 Hole - UD red

Beast Components RR40 Carbon Disc | Clincher | Rim - 20-622 - 24 Hole - UD red

With its aerodynamic shape, the Beast Components rim embodies pure speed on the road.

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.

Design & Innovation Award Winner 2019 


Beast Components RR40 road rim for 28"
Low weight, unique appearance and yet uncompromisingly stable and robust. 

The Solid Edge Design (2.8 mm rim flange width) and Framed Edge (circumferential layup on rim flange) gives a very sturdy rim flange that provides protection from delami­nation and can withstand heavy impacts.

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

Beast Components - Handmade in Germany

The Beast Carbon components are produced entirely in-house at the Black East GmbH in Dresden, Germany - here bikes are loved and lightweight construction is lived. The quite young company is a spin-off of the Rolls-Royce University Technology Centre, a dedicated engineering department at the Technische Universität Dresden. Thus, the scientific standard when working with carbon as a material is the first priority. Using state-of-the-art techniques from the automotive industry, aerospace and innovative manufacturing processes, the quality and practicality of road and mountain bikes is expected to benefit and improve significantly. Final stage geometry optimizations and life expectancy of fiber-reinforced plastics are central keywords here. 

With Beast Carbon components, the style comes to the bike - considerably lighter and stronger than ever before!


Weight supplement: manufacturer's information (UD finish), tolerance 5%.
