Featuring an innovative asymmetrical rim for the optimum aerodynamic profile and constructed from high-grade 1k carbon fibre in the pursuit of stiffness and low weight, the Roval 321 Rim Brake Carbon Disc Clincher is a top-of-the-line rear wheel designed for elite competition.

Roval 321 Rim Brake Carbon Disc Clincher Rear Wheel

The Roval 321 Rim Brake Carbon Disc Clincher was initially conceived as a part of a one-off project aimed at a shot at the UCI Hour Record, intended for use with a custom track frame. This slightly unusual beginning meant that Roval engineers had a huge amount of technical freedom to develop the fastest rear wheel structurally possible - and that freedom has come through into the final product.

This Disc is constructed from 1k carbon fibre for unsurpassed stiffness and an extremely low weight profile, while the rim shape has been rigorously developed using Computational Fluid Dynamics in order to create an incredibly fast wheel.

The standout feature of the 321 Carbon Disc is the asymmetrical rim profile. The lefthand lens features a single large curve, but the right-hand side has been shaped into an undulating profile that provides superb aerodynamics while leaving clearance for the rear derailleur. The rim itself has been built from a 1k carbon fibre formed into a single monocoque construction, offering a category-leading weight and stiffness profile.

The wheel is tubeless compatible and also features a wide 19mm internal rim width that is perfect for modern cycling's wider tyres and lower tyre pressures, providing a clean, aerodynamic transition from tyre to rim. The CeramicSpeed bearings, meanwhile, help to keep this wheel rolling fast and smooth, mile after mile.
