When we set out to create a lightweight disc wheelset, we didnÕt want it to be Òjust another climbing wheel." We wanted to provide you with the lightest disc wheelset out there with all the aerodynamic attributes of something twice its depth. It was a tall order, but in the end, our CLX 32 Disc not only delivers on this in spades, but it also provides incredible brake modulation and power in all conditions, increased impact resistance, and a disc-specific carbon layup that increases strength while decreasing weight.

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.

For the CLX 32 Disc rear, 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 740-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 rimÑit 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.
