Three years ago, Roval's engineers began an XC wheel project with one main goal in mind: create a light, race-ready option that Specialized's team athletes could use at the 2024 Olympics in Paris.
Roval already had a competitive set of wheels in their lineup in the form of the 1240 gram Control SL, but this project was intended to push things even further, and it ended up involving testing dozens of different hub and spoke prototypes before settling on the final product.
The Team Control SL wheels are the result, which use 20 straight pull carbon fiber spokes and heavily machined aluminum hubs to get the weight down to just 1190 grams, including tape and valve stems. That makes these some of the lightest XC wheels on the market, at least when it comes to a pre-built wheelset you can actually buy.
Roval Control SL Team Wheels
• Wheel size: 29"
• Intended use: XC race
• Rim material: carbon, 29mm inner width
• 20 straight pull carbon spokes
• Roval hub shell, DT Swiss internals
• Weight: 1186 grams (actual, w/ valves) | Front: 547 g / Rear: 639 g
• Price: $3,300 USD (includes 2 tires, wheel bag, spare bearings, Dynaplug tool, 2 water bottles)
On the topic of buying, Roval is only producing 400 Team Control SL wheelsets. The $3,300 price tag isn't just for the wheels, though; that includes two tires (a 29 x 2.35" S-Works Fast Trak and Renegade), a padded wheel bag, two water bottles, and a Dynaplug tire plug tool. On top of all that, Roval includes 20 spare spokes, a full set of extra bearings, plus a Microspline freehub body. It's a substantial package, but then it should be considering the cost.
Details The Control SL Team wheels use the same carbon rims found on the Control SL wheels, except there are only 20 holes drilled into them rather than 24. Roval also went with standard rim tape for these wheels, instead of the plastic plugs used on previous XC wheelsets.
The 29mm inner rim width is designed to work well with modern 2.3 – 2.4” wide XC tires, and the rim's sidewall is wider and flatter at the top in order to reduce the likelihood of a pinch flat. That design has proven to be very effective, but for riders who want even more security against flats the rims are approved for use with tire inserts.
It's the hubs and spokes that separate the Team wheels from the standard Control SL; those hub shells have been extensively machined and then covered with a clear coat to save as much weight as possible. As an extra-fancy touch, the signatures of the S-Racing team members are etched into the hub shell. The hubs use DT Swiss' SINC ceramic bearings, and contain their 180 internals with a 36 tooth ratchet ring.
As for the spokes, those were developed by Roval, and are proprietary to these wheels. They're said to be 29% lighter than a steel spoke (each one weighs just 3 grams, and the nipple is .38 grams), along with being stronger and more durable. The spokes are laced in a two cross pattern, front and rear.
Although these wheels were designed specifically for XC racing, I know there are riders out there wondering about putting them on not-quite XC bikes. According to Roval, the Team SL wheels are designed for XC and downcountry bikes, and are not approved for e-bike usage. Essentially, if your bike has more than 130mm of travel or a motor then these won't be the wheels for you.
Ride Impressions I'd meant for my first ride to be a medium speed cruise, but after running into some buddies on the trail it turned into an all-out sprint fest, and a good chance to see how the wheels felt at almost race pace. For an ultralight wheelset with only 20 spokes per wheel, the Rovals feel much more solid than I would have expected – they're super light without feeling sketchy, a trait that's not always present in this category.
The Control Team SL wheels took the place of a set of DT Swiss's new XRC 1200 wheels, which weigh around 1300 grams, so I can't say that the Roval's light weight smacked me over the head as hard as it would have if I'd been on some heavier hoops, but there's no denying that this a very fast set of wheels, especially when they're mounted up with quick-rolling XC race tires. They accelerate quickly, whether that's from a standstill or when pedaling out of a tight corner, with a satisfyingly zippy feel to them.
The lack of noise has been especially impressive. I've ridden plenty of light wheels that seem like they're actively warning you not to push hard in the corners, letting out pings and twangs that make it harder to trust that they're not going to fold over. The Rovals haven't let out a peep so far, and I've taken them on a good selection of rough trails that typically make noisy wheels sing.
I'd be remiss not to address that $3,300 price tag. Are they worth it? Well, that depends. We are talking about some of the lightest XC wheels in existence, so it's not surprising they cost a pretty penny. Plus, Roval really has put together a very nice package – the inclusion of race-ready tires, the spare bearings, and even the signatures on the hub shell do add extra appeal for deep-pocketed XC aficionados.
For riders who aren't quite as focused on shaving every gram possible, Roval's 28-spoke Control wheels uses the same rim design, weigh a still-reasonable 1450 grams, and cost $1,350 USD. Or there's the standard Control SL wheelset, which weighs 1240 grams, uses 24 DT Swiss Aerolite spokes per wheel, and is priced at $2,500.
I'm going to keep putting the miles on these wheels and will report back if any durability issues arise. The first fifty miles have been very promising, and it's easy to see why these would be the wheels of choice for several Olympic hopefuls.
Sure they’re a Chinese brand throughout, but their customer service is amazing and they’re superb rims.
Light bicycle has been around for a while and are trusted by many wheelbuilders I know.
Footnote: I have a 2nd gen R-Sys wheel which has had a decade of use and never even needing truing. That has carbon spokes on the NDS only.
Now if you have fatigue in steel spokes after riding with a broken spoke or two, you might as well replace them all. I don't have any experience to compare with carbon spokes, but the point I'm trying to make is that if the spokes aren't standard, better give me a good chunk up front and a guarantee they'll be available.
That said, roval seems to be decent with old parts, I just got a new end cap for my 2009 Control SL last year.
to allay fears of serviceability.
Probably biggest failure point will be the bonded nipple bit.
Anyone remember the Easton UST-tubeless rims with threaded nipples just like this?
These will likely ALSO get wound up, and do wacky stuff under load, except are carbon, so who knows what the hell that'll look like.
Probably OK from the factory, but a field mechanic will suffer for sure.
Oh well, ride em if ya got em!
Mavic followed that up with the fully molded CF wheel: two halves bonded in the center of the hub. Definitely road race whippet use only.
The current Control SL uses 24 DT Aerolight spokes both front and rear; a Aerolight spoke is ~4.3g, Berd ~2g; you're replacing 2 x 24 spokes; weight saving (4.3 - 2.5) * 2 * 24 ~= 85g.
A set of Control SL is 1240g, so you're not down to 1155g.
A Berd spoke is ~8USD, so 2 * 24 * 8 ~= 400USD
Labor cost, Berd will relace your exiting wheel for 200USD
MSRP for a set of Control SL is 2500USD
Total: ~3100USD.
spacedoutboy; Specialized's offering win.. more weight, more money, more fragile
I know it's 5 grams extra weight though
I've ridden my bike with roval control SL in a normal way, it means no jumps, or trails. I had two other guys with me, they saw. I used this track many times before, as I'm livin' here, I know well this stage of the rout. I've cracked my carbon wheel. There is no marks of external forces. I sent to Specialized Bicycles here comes their answer:
Hello Gergo,
Specialized rejected the warranty request.
This type of defect comes not from normal use, which is obviously from the marks.
The offer you a crash replacement rim. I asked them for more details and you get an update in the next days.
best regards
Lifetime guarantee
So I am not sure why this.
Really? They look pretty much identical to the normal black anodized Roval (powered by DT Swiss) straight-pull front hubs, just with 4 fewer spoke holes.
Is clear-coat less weight than ano? Polishing and no clear-coat nor ano would be even lighter...
I would be interested to see some impact testing comparisons between them and the Specialized wheels, but Newmen seems to be known for making highly durable wheels, so if they continued that tradition on their super light XC wheels then I would guess they're highly competitive in that regard as well.
Back in the olden days I learned to never ride the lightest of anything. That shit just breaks.
And if you are my weight (70Kg) a 1100-1200 wheel set is quite all-around. I owned a 27.5 1150 grams from lightbicycle and it was great on my XC bike.
Also +1 for BTLOS making some damn fine and affordable wheels.
