At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The Corima Essentia 40 is described as the ultimate all-road wheelset, and with compatibility with tyres up to 45mm they certainly have both gravel and road bikes covered. They are a decent weight overall, considering their intentions and pricing, and the 40mm-deep rims give an aero boost on the road.

With so many bikes straddling the lines between road and gravel, it's no surprise to see wheel manufacturers doing the same thing, and that is what we have here.
The Corimas are stiff and come with a deep enough rim that they're ideal for all kinds of general road riding, including faster sections, while still being a decent enough weight that they don't feel sluggish in the hills.
With a rim width of 28mm externally and 23mm internally, they'll take from a 28mm width tyre up to a 45mm, according to the text on the rim, so you can exploit all of those benefits on the local gravel tracks and byways. The build seems durable too – I certainly had no problems with them going out of true after a couple of months of testing on all sorts of terrain, and they'll take plenty of abuse from rocky trails.
I split the review period about 50/50 in terms of using the Essentias on the road or gravel bike, and the main thing I was impressed with was the ride feel. The excellent stiffness on out-of-the-saddle efforts didn't translate into a harsh or resonating ride. In fact, it is quite smooth, something I have found with other Corima wheels I've ridden over the years.
The 40mm-deep rim isn't as round in profile as many current wheels, it's a little more V-shaped but with a rounded leading edge. I found they reacted well against sidewinds, apart from when things got gusty, and there is no lag in the steering when leaning them over, like you can get with some deep-section carbon wheels at certain yaw angles.
The spoking pattern looks quite cool with the 24 spokes used front and rear positioned in pairs around the rim, and everything was tight and well tensioned straight out of the box. A few wheelsets arrive for reviewing that ping and go on the first ride as the tension settles, but there was none of that here.
For the freehub Corima has specced a ratchet system rather than the more typical pawl setup found on many wheels. With 36 teeth and 10 degrees between engagement points, they are not the quickest to lock in once you stomp on the pedals, but if you do trackstand with them you'll notice very little 'slop' as you rock backwards and forwards at the lights.
Specification-wise, Corima offers the Essentia 40s with Shimano HG, SRAM XDR and Campagnolo N3W freehubs, so plenty of options to suit the latest groupsets.
The rims are carbon fibre with a 3K layer finishing things off, which gives that chequerboard effect under the lacquer. I think it makes the wheels look more expensive than they actually are, which is always a bonus.
They are hookless in design, which won't to be everyone's taste – some people like the reassurance of a lip to tuck the bead of the tyre under.
This does also mean you can only use tubeless ready tyres, even if you want to run inner tubes rather than sealant. You are also limited to 75psi, which I know for most won't be an issue, but I like to run road tyres at a higher pressure than that, even 28s.
These wheels actually came fitted with the Continental GP5000 tyres you see in the photos, and when I swapped them over to some gravel tyres I found the fit snug but not so tight that you'd struggle to remove them when out on the road or trail, should the puncture fairy visit.
Both road and gravel tyres measured about a millimetre wider than their nominal sidewall width when fitted to the Essentias.
The Essentias are manufactured in Corima's own factories in France rather than just being assembled there from components made elsewhere. Bearing that in mind, I don't think the £1,301 asking price is excessive (they're listed as €1,490, currently reduced to €1,341, which equates to about £1,167.43).
Fulcrum's Rapid Red Carbons, which I tested last year, are designed for gravel use but are ideal for the road, too, although they don't have the same aero advantage, being just 30mm deep. That does mean they are a bit lighter than the Corima's 1,684g (including rim tapes and valves), but slightly more expensive at £1,399.
SwissSide's Hadron2 All-Roads have similar design intentions and come with 45mm-deep rims, which makes their overall weight of 1,530g impressive. The internal width is 22mm. They also use a ratchet freehub like the Essentias, and the rims are a similar shape, but they are hooked rather than hookless. They were priced at £1,442 when we tested them last year, but are now £1,249.
Heading in the other direction price-wise are the Just Riding Along Mahi Mahi Core wheels. They are designed as all-rounders too, and weigh in at 1,620g. JRA uses a direct to consumer method which means it can keep costs low – in this case, £700. But bear in mind, as I mentioned earlier, Corima's wheels are manufactured (not just assembled) in its own factories in France, which will also add a premium to their price.
The Essentias are a great set of all-rounders. In terms of price and weight there are many competitors, but I like the Corimas a lot, from their ride quality to the way they handle even on breezy days. They're looking good in terms of durability and reliability, too, which is ideal if you want a set of wheels to cover all kinds of riding.

Did the wheels stay true? Any issues with spoke tension?
The wheels remained true throughout the review period.
How easy did you find it to fit tyres?
I found both road and gravel tyres a bit snug to fit, which is reassuring for those being fitted to a hookless rim. Fitting and removing them wasn't tricky, though, so dealing with a puncture while out and about won't be an issue.
How did the wheel extras (eg skewers and rim tape) perform?
The tubeless valves and tape performed without issue.
Tell us how the wheel performed overall when used for its designed purpose
Deep-section rims can give a harsh ride, but these perform well in terms of comfort and ride quality.

As part of the tech team here at F-At Digital, senior product reviewer Stu spends the majority of his time writing in-depth reviews for road.cc, off-road.cc and ebiketips using the knowledge gained from testing over 1,500 pieces of kit (plus 100's of bikes) since starting out as a freelancer back in 2009. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 170,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him, he still likes to smash the pedals rather than take things easy. With a background in design and engineering, he has an obsession with how things are developed and manufactured, has a borderline fetish for handbuilt metal frames and finds a rim braked road bike very aesthetically pleasing!
