When Specialized set out to create a lightweight disc wheelset, they didn’t want it to be “just another climbing wheel." They wanted to provide you with the lightest rim brake wheelset out there with all the aerodynamic attributes of something twice its depth. It was a tall order, but in the end, the CLX 32 not only delivers on this in spades, but it also provides incredible brake modulation and power in all conditions.
The design process started with a low overall weight at the forefront, as they knew what weight could hit with the information and technology they had available. With that weight in mind, Specialized then turned 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 them with a 32 mm-deep shape that boasts more logged wind tunnel time than any other wheel in its category.
Once they found the most aerodynamic shape, at the 32-millimter depth, they came back to the weight focus and proceeded to experiment with over 40 different layup methods to reach the desired weight. And this made the CLX 32 lighter and faster than every other competitor in the lightweight wheel category.
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 handbuilt wheel also employs the legendary CeramicSpeed bearings and comes with DT Swiss hub and spokes.
