what it’s for, why it’s great
A genuine quiver-killer, the CLX 50 pairs a carefully designed rim profile with DT Aerolite bladed spokes. It is aerodynamically superior to many deeper rims, yet retains superb real-world handling, is light enough to climb with authority, and has racked up more pro wins than any other wheel—from Paris-Roubaix to World Championships to Grand Tour stages.
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
General
All Roval wheels are designed and tested as a system. This allows us to tune each wheelset specifically for the intended ride experience and deliver the highest quality wheels. For this reason, we do not offer individual components for sale.
Roval Road Wheels
Our CLX 32, 50, 64, Terra CLX, Terra CLX EVO, C38, SLX 24 and all Contol and Traverse models are compatible. Rapide CLX and Alpinist CLX wheels are not compatible with tubeless road tires. By making them tube-type specific we were able to create lighter and better complete wheels systems for performance road riders. To render these wheels tubeless would have required extra materials, and that extra mass would have outweighed the benefits of tubeless tires.
The wider CL(X) 32, 50, and 64 are compatible with tires between 22-47C. The previous CL(X) 40 and 60 models are compatible with tires up to 38C. Note that many Roval road wheels have a larger inner width than traditional road rims. Most road tires end up about 2mm wider on these wheels than on a traditional road wheel.
The wider CL(X) 32, 50, and 64 are compatible with tires between 22-47C. The previous CL(X) 40 and 60 models are compatible with tires up to 38C.
All Roval road wheels use DT Swiss internals. Stock DT Swiss replacement freehub parts are compatible with the rear wheels. Freehub bodies for virtually all component groups are available from your local Roval dealer. Please direct questions for specific part numbers to support@rovalcomponents.com
SCS is a system developed by Specialized Bicycle Components to ensure an ideal chainline and crisp shifting on disc brake road bikes with short chainstays. Wheels with SCS hubs move the cassette inboard (closer to the center of the bike). Select Roval models – CL(X) 40 and CLX 64 – are available with SCS rear hubs for use on certain Specialized Tarmac, Roubaix, Diverge, and CruX Disc models. Endcaps are available to use these wheels in both QR and SCS thru-axle configurations.
Our current generation CL(X) 32, 40, 50, and 64 wheels, along with SLX 24 disc wheels, are compatible with traditional QR and thru-axle configurations. In the front, this is 9x100mm QR and 12x100mm thru-axle. In the rear, this is 9x135mm QR and 12x142mm thru-axle. The end caps for these configurations all ship with each aftermarket wheel.
We have partnered with Swiss Stop and optimized our brake tracks for their Black Prince brake pads. These brake pads are available for Shimano/SRAM and Campagnolo configurations, and they're easy to find at either your local bike shop or online. Use of a brake pad other than the Swiss Stop Black Prince or the Roval “Red” pads will void your warranty and can be unsafe.
Roval Mountain Wheels
All Roval Mountain wheels use DT Swiss internals. Stock DT Swiss replacement freehub parts are compatible with the rear wheels. Freehub bodies for virtually all component groups are available from your local Roval dealer. Please direct questions for specific part numbers to support@rovalcomponents.com.
All Roval wheel small parts are available through your local Roval dealer. For technical questions please contact support@rovalcomponents.com.
The spoke lengths and type vary by wheel. Please contact your local dealer or support@rovalcomponents.com, and we'll get you sorted.
This depends on a ton of variables. Trail type and conditions, rider weight and style, tire casing, and internal rim width all play a part in choosing the proper combination. As a general baseline, we recommend the following: 22mm internal rim width – 2.0 - 2.3” tire; 29-30mm internal rim width – 2.3 - 3.0” tire; 38mm internal rim width – 2.6 - 3.0” tire
Current generation Control and Traverse wheels (all wheel diameters and hub spacing types) are compatible with the plugs.

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.
Composite shop
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.
