There are a number of familiar brands that offer similar products like Zipp, Enve and Mavic, and now Roval, owned by Specialized, is making a big push for your consideration. The line consists of three models, the CLX 32, CLX 50 and CLX 64, each model noting the rim depth. Roval brought a group of journalists out to Santa Cruz, Calif. to show off this new line this winter. So here’s a look at the salient considerations.
Weight and measurements
These are the easiest criteria to nail down, so let’s just do the numbers with the rim brake, clincher versions of a few well-known wheelsets:
Roval CLX 32: 1,280g | $2,400 | 32mm rim depth
Zipp 202 Firecrest: 1,375g | $2,100 | 32mm rim depth
Enve SES 2.2: 1,370g | $2,900 | 25mm rim depth
Rolf Aeres3: 1,340g | $2,399 | 35mm rim depth
Roval CLX 50: 1,375g | $2,400 | 50mm rim depth
Zipp 303 Firecrest: 1,625g | $2,100 | 42mm rim depth
Enve SES 3.4: 1,450g | $2,900 | 35mm front/45mm rear rim depth
Rolf Aeres4: 1,365g | $2,399 | 42mm rim depth
Roval CLX 64: 1,545g | $2,400 | 64mm rim depth
Zipp 404 Firecrest: 1,690g | $2,100 | 58mm rim depth
Enve SES 4.5: 1,526g | $2,900 | 48mm front/56mm rear rim depth
Rolf Aeres6: 1,545g | $2,399 | 60mm rim depth
While many manufacturers use hidden nipples to provide more aerodynamics, Roval uses external nipples, which make it easier for your mechanic to true them during a tune-up. Roval’s hubs have DT Swiss internals, which have proven reliable in our testing. And, the wheels are all laced by hand with DT Swiss Aerolite spokes (16/21 lacing on the CLX 50 and CLX 64; 16/24 on the CLX 32), to rims that all have 20.7mm internal width, in keeping with the trend toward wider rims. While a few other brands champion their American production facilities (Enve’s SES wheels, for instance, are entirely manufactured and assembled in Utah), Roval wheels are manufactured and assembled in Taiwan. Naturally, a product’s country of origin may be intangible when riding or irrelevant to some, but that may be partly why Roval wheels are competitively priced.
The CLX 32 wheels are our favorites of Roval’s current offerings, perhaps because we’ve spent the most time on them, both at the California press event and back in Colorado on a rim-brake specific pair. Lively, light, but plenty stiff, the CLX 32 is a great wheel for almost anything but full-gas group rides on flat or rolling roads. The low-profile rim behaves itself in crosswinds and is noticeably zippy on steep climbs.
In our laboratory, the CLX 32 was stiff in deflection testing, although not category-leading. The rim brake version deflected 5.2mm in the front and 6.57mm in the rear; compare that to Mavic’s Ksyrium Pro Carbon SL C, which deflected 4.54mm front/5.88mm rear.

For triathletes, the CLX 64 would be a sensible choice for racing, or even for a single pair of do-it-all wheels. We have yet to take these wheels to the lab, but they felt stiff and precise on the road. Also, our limited time on the 64s didn’t afford a chance to see how they felt in crosswinds. Roval engineers explained that, rather than shaping and adding texture to the rims, as Zipp did with its 454, or using a lower-profile front rim, like Enve, they focused on pure aerodynamics. They say that rims that afford a smooth separation with the wind as it passes will not compromise steering torque. Read the full Ro
We didn’t get a chance to ride the CLX 50, but from our time on the other two sets we think this 50mm option would be a great choice for smaller athletes, or any racer who’s more concerned about handling on windy days than they are about aerodynamics.
Based on our longer-term experience with the CLX 32 wheelset, Roval’s new three-pronged approach to its wheel line is promising. Certainly the brand has come a long way since Specialized bought it in the early 2000s—ah, remember these? However, like other brands that live in the shadow of a larger ownership company, such as Bontrager, riders aren’t always thinking Roval when it is time to buy race wheels. Perhaps they should.
Our Roval takeaways:
– They hit a competitive price point. Yes, $2,400 is a lot to spend on wheels, regardless of how fast they are, but compared to offerings from other brands, it is close.
– They are lighter than most in nearly every category.
– We like the combination of DT Swiss hubs and spokes—not proprietary, easy to service, compatible with nearly every axle configuration, and available at most bike shops.
– When it comes to the intangible ride feel factor, the CLX 32 wheels are great, and we’re probably going to keep on riding them until Specialized tells us to send them back.
A note on Aerodynamics: We haven’t seen independent aero data on Roval wheels. According to Specialized’s wind tunnel research, the three CLX models out-performed their closest equivalents in Zipp’s line. Naturally, we take any proprietary manufacturer data with a grain of salt.
