Roval wheelsets with carbon rims are designed for a maximum rider weight of 240lbs (109kg). Our alloy wheelsets, however, do not have a weight limit.

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 Aero Flange 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.

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!
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.

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 firstname.lastname@example.org
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 email@example.com.
All Roval wheel small parts are available through your local Roval dealer. For technical questions please contact firstname.lastname@example.org.
The spoke lengths and type vary by wheel. Please contact your local dealer or email@example.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
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.
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.
