Review: Clément Ushuaia Gravel Wheelset
GRAVELCYCLIST.COM | JOM - “In cycling, the name CLÉMENT is as legendary as the many champions who logged time and wins on our classic silks. Names like Eddy Merckx, Jacques Anquetil, Felice Gimondi, and Ole Ritter to name a very few. Ours were bicycle tires known and coveted for their speed, comfort, and performance; with names like the CLÉMENT Paris Roubaix and CLÉMENT Criterium Seta.”
For many years, Clément has specialized in the manufacture of cyclocross and gravel tyres. Late in 2016, the company created a set of gravel specific tubeless wheels featuring, solid, no nonsense construction centered around high quality hubs and rims; the Clément Ushuaia.
Interesting fact: USH is the airport code for Ushuaia on the island of Tierra del Fuego, Argentina. Ushuaia is a resort town on the Tierra del Fuego archipelago, the southernmost tip of South America and is nicknamed the “End of the World”. The windswept town, perched on a steep hill, is surrounded by the Martial Mountains and the Beagle Channel. It’s the gateway to Antarctica cruises and tours to nearby Isla Yécapasela, known as “Penguin Island” for its penguin colonies – Source, Wikipedia.org
Ushuaia also happens to be the southernmost city in the world.
The wheels come pre-taped and measure 23mm internally / 26mm externally.
A wider rim allows for increased air volume, and helps to spread the tyre casing. That also helps increase the tyre’s contact patch with the ground. Other benefits are improvements in cornering grip and increased overall comfort.
The 25mm deep Ushuaia rim is a hookless, tubeless rim design, which Clément claims can fit tyres ranging in width from 28mm to 50mm wide. To prevent burping (the loss of air), the rim bed has a small lip to keep the tyre pressed up against the rim.
Keeping with trend set by the Ushuaia’s stout rims, the wheelset is built with 28 double butted J-bend spokes front and rear, brass nipples, and hub flanges angled in line with the spokes to help reduce stress.
The hubs are designed with maximum frame and fork compatibility in mind. They support quick release and thru-axle; 12mm front, 15mm front and 142mm x 12mm rear. You will need to choose your preferred brake rotor standard when buying these wheels – center lock or 6-bolt.
Wheel Weights and More Tech Specs
With rim tape and the supplied valve stems / cores installed, the wheelset tipped the scales at 1,614 grams, six grams below the manufacturer’s specified weight. Typically, manufacturers weigh wheels sans rim tape or valves, so this was a nice little bonus. Well done Clément!
The rear hub features 36 points of engagement, a Shimano / SRAM 10 / 11 speed freehub cassette body or SRAM XD.
The hubs feature sealed cartridge bearings that can be easily replaced when the time comes.
I decided to pair the Ushuaia wheelset with another bike I have in for review at the moment, the Wilier Triestina Jaroon (a steel gravel bike). Without giving too much away about that future review, the Jaroon benefited greatly from this wheel upgrade.
The Wilier Triestina Jaroon features 12mm thru-axles front and rear, but the Ushuaia wheelset arrived setup for 15mm on the front wheel. Thankfully, the wheelset’s system of end caps caters to all axle standards. I used a flat bladed screwdriver to gently tap out each end cap. Just be careful not to tap out the bearing.
In the photo above, I’m about to insert the 12mm thru-axle end cap. In all, the process to convert between axle types took about two minutes.
Disc Rotor and Tyre Installation
As alluded to earlier, the Ushuaia’s hubs are available for center lock rotors or the older 6-bolt standard. There are advantages to both, but the big advantage for center lock is speed and ease of installation. This is especially handy if you’re a gravel bicycle / components reviewer!, professional mechanic, and to a lesser degree, a home mechanic. If you find yourself frequently swapping brake rotors, with the appropriate tool, it takes just a few seconds to loosen the lockring, swap rotors, and re-install the lockring.
The Ushuaia review wheels in my possession were compatible with 6-bolt rotors, which I fitted with a set of Shimano 160mm Icetech rotors. For this review, I had no requirement to swap rotors, so it set and forget.
For the duration of the review, I mounted and ran two different tubeless gravel tyres with the review wheels. The Panaracer Gravelking SK in 700c x 35mm and the Maxxis Ravager in 700c x 40mm, both paired with Orange Seal Endurance formula sealant. Both tyres mounted easily to the wheels, sans struggling with a tight fit or the need to use tyre levers. The tyres aired up nicely with Bontrager’s TLR Flash Charger pump (review on that product coming soon), but I’d expect the Topeak Joe Blow Booster pump would have no troubles either – or there is always the venerable air compressor.
Weighing just over 1,600 grams, the Clément Ushuaia’s are light enough that they accelerate well, but don’t expect performance to be on par with a wheelset that weighs 200 grams less. Remember, gravel cycling / racing is all about endurance – chugging along, riding at a steady speed. Once the Ushuaia’s are up to speed, they hold that speed nicely and stay there. The wheel’s unbranded double butted steel spokes aren’t fancy, but are spot on for the job, and if you like the stealth look of a wheelset with subtle logos / decals, you’ll enjoy the overall look of the Ushuaia wheelset.
In this day and age of hubs with an ever growing number of engagement points, I was very happy with the Ushuaia’s hubs and their 36 points of engagement. In a nutshell, that means at worst case scenario, 10 degrees of movement in the hub has to occur before the forward driving mechanism is engaged.
I’ve ridden hubs that feature 60 points of engagement which are borderline overkill for gravel, but I can appreciate a fast engaging hub, especially if one is carefully finessing one’s bike through a tricky patch of sand, gravel or mud at slow speed. Freewheel operation is relatively quiet, just how I like it.
