Modern rim widths for modern tires
Tires are (finally) getting wider as riders everywhere begin to accept the superior efficiency and comfort benefits of wider tires. Using the same rim as our CLX 50, the CL 50 is perfectly suited for supporting new school rubber, with an inner rim width of 21mm. Additionally, the rim’s aerodynamic profile has been carefully shaped to optimize efficiency around wider tires.
A shape for all conditions
Just like the CLX 50, the CL 50 rim tests faster than shallow rims in ALL conditions, even heavy crosswinds. Aerodynamically, it outperforms many deeper-section aero rims without suffering the weight and handling drawbacks associated with deeper wheels. And it weighs a whole bunch less, too, making the CL 50 an ideal all-condition aero choice.
Faster, stronger hubs
The Aero Flange hubs found on each CL 50 wheelset are the basis of a fast, strong, light, slippery wheel. They are aerodynamically optimized, with wide bracing angles for increased strength and reduced spoke weight. In order to deliver exceptional durability and value, we hand lace hubs to rims with DT Swiss Competition spokes and finish the package with high quality DT Swiss 350 hub internals.

Tire pressure recommendations
The right tire pressure for your ride is personal and depends on your riding style, the terrain you'll be riding, and the conditions of that terrain on the day you're riding. What you see below is a recommended starting point, a "ballpark." You'll also see a decal on your wheels indicating max pressure. Never exceed the max pressure. Enjoy your ride!
How we made it
Using the aerodynamic data gleaned from the CFD process, our technicians created 3D printed models of the CLX 50 rim and tested them in our wind tunnel. Working 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 CLX 50 rim design.
We engineer and build our wheels as an integrated whole to deliver performance that can’t be achieved by designing a rim and then sourcing third party parts for the rest. Example? We layup the CL 50 rims and drill spoke holes at precisely the angle the nipple will interface with the rim, ensuring reliability and the lightest weight possible.
