CLX 64
The fastest spoked wheel in the world
CLX 64
The fastest spoked wheel in the world
what it’s for, why it’s great
An all-conditions aerodynamic wheel with a fistful of world championships to back its swagger, the CLX 64 mixes world beating aerodynamics with real world usability. It induces less drag than most 80mm-deep wheels and weighs a half pound less than other aero competitors.

Modern rim widths for modern tires
Tires are (finally) getting wider as riders everywhere begin to accept their superior efficiency and comfort benefits. The inner rim width of the CLX 64 is 21mm, which makes it perfect for supporting new-school rubber, and the rim’s aerodynamic profile has been carefully shaped to optimize efficiency around wider tires.
The ultimate aerodynamic advantage
This is the most aerodynamically efficient spoked wheel in existence. The 64mm rim profile is the result of extensive wind tunnel testing, and is proven to be more efficient than most 80mm deep rims. Superior aerodynamics in a shallower rim means better gusty wind performance, dramatically less steering torque, and more speed everywhere. Less material also means that the CLX 64 is over a half-pound lighter than most of the competition, making it faster up hills and in sprints.
Faster, stronger hubs
The Aero Flange hubs found on each CLX 64 wheelset are the basis of this fast, strong, light, slippery wheel. Aerodynamically optimized, with wide bracing angles for increased strength, they also feature ultra-smooth CeramicSpeed bearings and the refined precision of DT Swiss 240 freehub internals.
The human touch
The premium components that make up this wheel are assembled together into the final product by hand. They are laced, tensioned, checked, and tensioned again by practiced, professional craftsmen; an added layer of quality control that machines cannot match.

How we made it
Computational fluid dynamics
Leveraging powerful Computational Fluid Dynamics (CFD) was key to the aerodynamic optimization of the CLX 64. CFD enabled our engineers to very closely estimate the drag that the wheel would generate. They then utilized that data to revise the shape of the rim in the computer until it was close to perfect.
Wind tunnel
Once CFD data indicated an aerodynamically optimized shape, our technicians created 3D printed models of the CLX 64 rim and tested them in our wind tunnel. By testing the physical model at various yaw angles, with a real tire mounted, installed in a real bike, the team generated drag data that was used to further optimize the final rim profile.
