what it’s for, why it’s great
A pure climber's dream, the new Alpinist CLX is the lightest road clincher wheelset we have ever made. When climbing, mass is the enemy of performance, so we pared the Alpinist CLX down to the absolute minimum to capitalize on every precious watt of energy without sacrificing any of the strength, ride quality and durability that are crucial to long term performance and satisfaction.
Systems Approach
In order to create a 1248-gram wheelset, we developed each wheel as a complete system. By making wheel systems, not just rims, our engineers can control every aspect of the design; rim, hub, spoke spec and lacing pattern. This eliminates variables associated with off-the-shelf components, which in turn allows us to optimize weight and strength. Bottom line - the Alpinist CLX has precisely the amount and type of material needed, in precisely the correct place, and not a gram of fat anywhere.
Rim Layup
For the Alpinist CLX rim, we utilized a complex and precise carbon fiber layup schedule in order to minimize weight, optimize strength and durability, and serve up a smooth riding, superb handling wheel.
Lighter, Stronger, Faster
Our AeroFlange hubs form the basis of strong, light, fast wheels. Aerodynamically optimized, with wide bracing angles for increased strength and reduced spoke weight, they also benefit from the reduced weight, increased strength and reliability of DT Swiss’ new EXP freehub internals.

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.

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
Composites Shop
To optimize the strength and weight of our rims, we define exactly where we need to place carbon fiber, what type of carbon to utilize, and the orientation of the fiber. The final layup schedule defined during prototyping in our California composites lab becomes the guide used when the wheels reach the production stage. It’s part hard number crunching; part black art; and part, test, destroy, redesign and repeat until we reach our goal.
Testing
Good design only gets you so far. We are relentless in our testing. Days on end spent in our wind tunnel, hour upon grueling hour in the test lab, field testing, and the explosive power of World Tour professionals all contribute to bringing our wheels to life. Every step of the way we seek the fastest, lightest, best handling, smoothest riding path. Once our wheels have proven themselves across all these criteria, and survived these arenas, they are ready for you.
