Roval CLX 32 Disc – Front

Our design process started with a low overall weight at the forefront, as we knew what weight we could hit with the information and technology we had available. With that weight in mind, we then turned our focus to aerodynamics and began an iterative process of designing and testing over 150 individual rims to find the optimal shape. These innumerable Computational Fluid Dynamics (CFD) models, Win Tunnel hours, and shots of espresso left us with a 32mm-deep shape that boasts more logged wind tunnel time than any other wheel in its category.

Once we found the most aerodynamic shape, at the 32-millimter depth, we came back to the weight focus and proceeded to experiment with over 40 different layup methods to reach our desired weight. And this made the CLX 32 Disc lighter and faster than every other competitor in the lightweight wheel category.

For the CLX 32 Disc front, we mated the rim to our Aero Flange (AF) series hub with DT Swiss Aero spokes to create the best overall system. This resulted in a 610-gram, 21mm-wide (internal width) front wheel with an extremely low inertia value. In cycling, inertia relates to the amount of force it takes to accelerate or decelerate, so wheels that are built with lightweight rims, like the CLX 32, result in a lower inertia value that creates a lively wheel that allows you to accelerate, decelerate, and change direction with less effort. But why so wide? Well, additional width does three primary things for a rim—it provides additional structural strength, it allows for a clean rim and tyre interface when using wide tyres (resulting in enhanced aerodynamics and faster rolling properties), and it better supports the tyre in hard cornering. This boosts both predictable grip and confidence when things get twisty on the descents.

Each front wheel also employs the legendary CeramicSpeed bearings and comes with our padded wheelbag, quick-release, tubeless plugs, and a tubeless valve.
