The Roval Rapide CL II is built for riders who want deep-section speed without turning every gust of wind into a wrestling match. In practical terms, it is a tubeless-ready, hooked-bead carbon wheelset with a deliberately split front-and-rear profile, and that design choice matters more than the marketing gloss. In this article I focus on the details that actually help you buy and use it well: tyre choice, handling, setup, and where the compromises show up on UK roads.
The practical takeaways before you decide
- It is a road wheelset, not an off-road or gravel wheelset. The 700c disc-brake format and aero rim shape are aimed at fast tarmac riding.
- The rim shape is the real story. The front is wider and shallower for stability, while the rear is deeper for aero efficiency.
- 28mm tyres are the safest all-round bet. The official tyre range is broad, but 26 to 28mm usually makes the most sense for everyday use.
- It is tubeless-friendly, but not tyre-change friendly in every case. Tight beads can make fitting and removal awkward, especially with some tyre brands.
- The value proposition is strong. You get the flagship rim design without paying for the most exotic hubs and spokes.
- The UK use case is clear. Fast club rides, sportives, racing, and exposed roads are where this wheelset earns its keep.
What the wheelset actually is
I see this wheelset as Specialized’s value play inside its aero road family. It borrows the same rim concept as the higher-spec CLX model, then pares back the hubs, spokes, and bearings to land at a more accessible price without feeling like a cut-down training wheel.
That means the headline features are still serious: deep carbon rims, tubeless compatibility, a hooked bead, and a build that is meant to work as a system rather than a pile of parts. The hooked rim is important because the tyre bead locks under a physical rim hook, which gives you more tyre flexibility than a hookless design and makes life easier if you want to run tubes sometimes and tubeless other times.
| Feature | What it means in practice |
|---|---|
| Wheel size | 700c, disc brake only |
| Rim depth | 51mm front, 60mm rear |
| Internal width | 21mm |
| External width | 35mm front, 30mm rear |
| Tyre range | 24 to 38mm approved |
| Claimed weight | 1,590g for the set, including tape and valves |
| Hub | DT Swiss 350 with 36-tooth Star Ratchet internals |
| Weight limit | 125kg system weight |
| Setup style | Tubeless-ready, but still usable with tubes |
That spec sheet tells me exactly who this wheelset is for: riders who want fast road performance first, and do not want to pay flagship money for it. If your riding regularly leaves the tarmac, I would treat it as the wrong tool. That brings us to the part that looks unusual at first glance: the split front-and-rear design.
Why the front and rear rims are different
The split-rim approach is the clever bit. The front wheel has the bigger job when the wind hits, because it controls steering feel and rider confidence. That is why the front rim is wider and a little shallower: it is designed to stay calmer when gusts, vans, or bridge crossings try to push the bike sideways.
The rear wheel can afford to be deeper because it does not influence steering in the same way. That deeper profile trims drag where the wind leaves the bike, so you get aero benefit without making the front end nervous. Specialized says this front-end optimisation improves stability in sudden gusts compared with its earlier 50mm rims, and that matches the basic logic I would expect from the shape alone.
On UK roads, I care more about that than any wind-tunnel headline. A wheelset that is fast in still air but twitchy on exposed roads becomes tiring in the real world, especially on open A-roads, coastal routes, or winter rides where crosswinds are common. This one is clearly trying to solve that problem rather than pretending it does not exist.
Once that handling picture makes sense, the next question is simpler: which tyres actually make the most of the rim shape?
Which tyres make the most sense
The official tyre window is broad, from 24 to 38mm, but that does not mean every width makes equal sense. In my view, the sweet spot depends on whether you care more about race speed, all-day comfort, or keeping the rim protected on rougher British roads.
| Tyre width | How I would use it | Main tradeoff |
|---|---|---|
| 26mm | Best if you want the sharpest aero look and race-day road feel | Less rim protection and a slightly harsher feel on broken surfaces |
| 28mm | My default recommendation for most UK riders | Slightly less “pure aero” than 26mm, but far better real-world balance |
| 30 to 32mm | Good for rough lanes, endurance rides, and riders who prioritise comfort | More tyre bulk on the front rim and a little more aero compromise |
| 24 to 25mm | Only for very specific race setups | Too narrow for most riders and not the choice I would make for UK roads |
There is one practical wrinkle worth calling out: tyre fit can be tight. Some riders love the secure fit, while others find certain tyre combinations stubborn to mount or remove. I would treat that as a normal consequence of a snug hooked-bead design, not as a defect, but I would still test your tyre choice at home before race day.
If you plan to run tubes, you will also need extra-long valves because the rims are deep enough to make short stems awkward. If you plan to run tubeless, the setup is more forgiving than a hookless race wheel, but I still would not treat the 110psi ceiling as a target. It is simply a ceiling. For most riders, the smarter approach is to choose the tyre that suits the road surface first, then set pressure around comfort and grip rather than headline numbers. That naturally leads into ride feel, because that is where the wheelset either earns its keep or does not.
How it rides on British roads and in crosswinds
The first thing I notice on the road is that it holds speed very well once it is up to pace. It feels like a wheelset that rewards steady effort on flat and rolling terrain, which is exactly where aero rims should make a difference. It is not a magic climbing wheel, but it is light enough that it does not feel dead when the road tilts upward.
Where it stands out most is crosswind behaviour. I would still call it a deep wheelset, so you know you are riding something with presence, but the front-end behaviour is much calmer than a traditional matched deep-rim set. On windy days, that matters more than people admit. If you ride through exposed countryside, over bridges, or along hedged lanes with sudden gusts, the wheelset’s stability becomes a real performance feature, not just a marketing line.
The compromise is comfort and practicality on rougher roads. A 60mm rear rim and a wide front profile will never feel as forgiving as a shallower, climbing-focused set, and the tyre fit is not as forgiving as on a plain alloy wheel. I would be especially careful if the bike is loaded close to the 125kg system limit, or if you regularly carry winter kit, tools, and full bottles. In that case, tyre choice and pressure matter more than rim depth alone.
Once you understand how it rides, the decision mostly comes down to whether you should buy this model or step up, step down, or look elsewhere.
Rapide CL II versus the obvious alternatives
If I were choosing between the CL II and the obvious alternatives, I would think in terms of how much performance I actually need to pay for. The rim shape is the expensive part of the story here; the rest of the package is where Specialized saved money.
| Option | Best for | Why I would choose it |
|---|---|---|
| Rapide CL II | Most riders who want aero speed and sensible value | Same rim concept as the flagship, but with cheaper hubs and spokes that make the price far easier to justify |
| Rapide CLX II | Riders chasing the lightest and most premium road build | Lighter, more exotic hardware, and the sort of finish that makes sense if you care about the last few percent |
| Roval Alpinist CL II | Climbing, all-day rides, and more upright road comfort | Shallower rims suit rougher or hillier riding better when outright aero speed is not the priority |
My own view is simple: if you want the CLX II rim shape, the CL II is the smarter buy unless you are specifically chasing the premium hub and spoke package. The speed gap should be small in real life, while the price gap is large enough to matter. If your riding is more about long climbs, rough lanes, and constant comfort, a shallower wheelset is the better fit and you should not force the aero option just because it looks fast.
That comparison only works if the bike and the setup suit the wheel in the first place, which is why I always check a few basics before spending the money.
What I would check before buying in the UK
- Make sure your bike is built around 700c disc wheels with 12x100 front and 12x142 rear spacing.
- Decide in advance whether you want tubeless or tubes, because the valve length and tyre choice change depending on that decision.
- Start with 28mm tyres unless your bike fit or racing plan clearly points elsewhere.
- Test tyre removal at home. If you cannot break the bead and refit the tyre in the garage, you will not enjoy doing it on the roadside in the rain.
- Remember that the 125kg system limit includes rider, bike, clothing, bottles, tools, and anything else carried on the bike.
- Check whether you are buying a full pair or replacing a single wheel, because that changes the value calculation more than people expect.
My short take is this: the Rapide CL II makes sense if you want a fast road wheel that behaves well in real wind, accepts modern tyres, and keeps the spend below the flagship. I would buy it for fast club rides, sportives, and race days on tarmac; I would skip it for gravel, trails, or any setup where absolute tyre-change convenience matters more than aero speed.
