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 50 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.
A shape for all conditions
The CLX 50 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. At 200-grams lighter than the closest competition, the CLX 50 is an incredible all-conditions choice.
Faster, stronger hubs
The Aero Flange hubs found on each CLX 50 wheelset are the basis of this fast, strong, light, slippery wheel. Aerodynamically optimized, with wide-bracing angles for increased strength and reduced spoke weight, they also feature ultra-smooth CeramicSpeed bearings and the refined precision of DT Swiss 240 freehub internals.
The Aerolite advantage
As befitting a premium wheelset, there is no skimping on the details here. Our Aero Flange hubs are hand laced with DT Aerolite bladed spokes, which test measurably faster than round spokes. Note the paired spoke lacing pattern, proprietary to our system-designed wheels. This 2:1 pattern emphasizes strength on the drive side of the wheel where all the torque forces are applied, with half as many spokes on the non-drive side ensuring the lightest possible weight and maximum aerodynamic benefit.

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
Field testing with the pros
Alaphillipe, Sagan, Remco, Duffy, Luis, and scores of other top pro road racers and triathletes have tested (and won on) CLX 50 wheels. Their continual feedback from prototype through production enables us to perpetually improve the performance of our products. The victories they’ve racked up at World Championships, Olympics, and Spring Classics are the ultimate proof of concept.
Before a wheel goes into production, we perform all of the engineering, prototyping, and iterating in our Northern California innovation center. This includes machining the massive molds as well as laying up and producing the prototype rims. This kind of integrated, hands-on approach accelerates development and enables optimization that’s simply not possible any other way.
