The WH7850 CL Carbon Laminate wheel earn the Dura-Ace pedigree and are designed to complement any of their 10-speed groupset whilst meeting pro road race criteria.
Carbon and alloy laminate clincher rim is both light weight and ridged whilst maintaining high braking performance with standard brake pads. Low rim weight is achieved by reducing the alloy wall thickness from 1.3 mm down to 0.7 mm, then a patent pending phosphoric acid anodizing process is used to bond the carbon fibre to the alloy giving an excellent combination of low weight, strength and rigidity.
Shimano are the makers of the world's most well known cycle component brand. Established in 1921 when the first cycle freewheel was forged. Shimano produce drivetrains, wheels, pedals, shoes, cycling clothing and pretty much every Shimano cycle accessory you can think of! Famous for their top end products ridden by the pro's, Dura-Ace and XTR, which cover both road and MTB's. At Shimano, they're doing everything they can to respond to heightened environmental concerns. Shimano are proud to be a producer of bicycle components that help people to enjoy outdoor sports and interact with nature through healthy non-polluting activities.

Richard Hallett and I have been giving the long term test treatment to Shimano's Carbon 1380 wheel sets but, while Richard has analysed and dissected the engineering of the carbon laminate technology with surgical precision, noting every nuance in their ride characteristics, I on the other hand had a simple aim; to put them through everyday abuse and, having dusted them down after 6 months of riding, assess their quality, longevity and value for money.
I have mated them to carbon, flax/carbon and aluminium frames and shod them with 23mm tyres from 4 different manufacturers and they have delivered excellent performance in all situations.
They are notably 'springy' whilst still retaining quick responses to rider input, either in thrust or direction. Personally I like a lively, springy set of wheels and often find factory wheels very efficient but slightly lifeless, a trait not shared by the 1380's.
Unlike Richard's set I haven't had to wield a spoke key on them or suffered from any noticeable freewheel jump but top marks must be reserved for the hubs, which run as freely and smoothly now as they did in April. No adjustment has been necessary and, unlike some other factory wheels I've used over the last couple of years, there has been no seal failure in even this most torrentially wet of summers.
One thing is clear however; despite these wheels being a bargain and a fantastic choice for an upgrade wheel, I wouldn't want to expose their aluminium spoke nipples to the ravages of salt-strewn roads.
Top quality summer race or sportive wheels
The remit for Shimano engineers was to create a new wheel for clincher tyres with a strength-to-weight ratio that equalled that of a 100 percent carbon wheel. They also had to be affordable, and have the superior performance of an aluminium braking surface.
To do this Shimano has employed a new jointing process. This enables the fusing of an aluminium extrusion of half the normal thickness for the braking surface and well of the rim to a carbon fibre mid section.
Additional layers of carbon material are applied to the rim around the vulnerable area of the spoke holes, and these are offset to one side on the rear rim to minimise the dish that is inevitable on all wheels that use derailleur gears.
Shimano remains true to traditional cup and cone ball bearings in the hubs. They can be be stripped and re-greased. There are changes to the hub body to improve reliability and, Shimano claims, strength, by using more pulling spokes than with the previous model. There are also improvements to the seals to make them more weather-resistant.
Shimano has also ditched the dedicated 10-speed freehub body in favour of one that can also be used with earlier 9-speed Shimano cassettes. The new freehub body is claimed to provide 125 per cent faster engagement.
These wheels give the Mavic Ksyrium SL Premium and Bontrager Race X-Lite a run for their money with their stability at high speed. But it's on the climbs that they exceed expectations and where they are directly comparable with wheels costing more than twice the price.
Confusingly the Dura-Ace moniker is also attached to Shimano's Scandium-rimmed wheels for tubeless and clincher tyres and there's a Dura-Ace wheel with 100 per cent carbon rims for tubular tyres.
Superb wheel at any price, and almost perfect for Shimano users
Shimano's top-end clincher road wheels, the Dura-Ace WH-7850-C24-TLs, don't exactly blow you away on paper.
They're light but not appreciably lighter than the competition at 1,482g per pair (without skewers), the shallow 24mm-deep rims don't come off as particularly aerodynamic, the hubs go about their business free from the hype of hybrid ceramic cartridge bearings, and the subdued silver-and-dark grey aesthetics are typically restrained.
Yet none of that means a thing once you get them out on the road. Ride quality is simply sublime with one of the smoothest overall feels we've encountered in any clincher - a magical combination of the shallow near-box section profile, paper-thin scandium-enhanced aluminium rim extrusion and co-moulded carbon fibre reinforcement.
Road buzz is soundly squelched, medium-sized impacts are nicely muted, and even bigger breaks in the tarmac come through with little more than a modest 'thud'. Add some appropriate Road Tubeless rubber to the compatible rims and the performance metrics go up even higher.
In addition to the extra comfort and traction from the recommended lower pressure relative to tube-type clinchers (we run about 95psi with tubeless in contrast to about 105psi otherwise), ditching the tube also nets improved puncture resistance while maintaining an impressively smooth roll.
Two-cross/two-cross rear spoke lacing and widely spaced front hub flanges yield fantastic torsional and lateral stiffness for outstanding responsiveness, both under power and in hard corners. The Dura-Ace wheels feel lighter than they are (likely on account of having weight concentrated at the hubs) and there's no sense of the twang, pop or wind-up that can often accompany bona fide featherweights.
As extra bonuses, build quality has been superb with no truing required over six months of testing, the aluminium braking surface is more progressive and predictable than carbon, and while the rims aren't particularly slippery, Shimano at least see fit to include bladed spokes.
Aside from the proprietary straight-pull forged aluminium shells, the hubs are based on Shimano's own Dura-Ace 7800 design and include a faster engaging (relative to older Shimano designs) and hard wearing titanium freehub body, oversized alloy axles, and cup-and-cone bearings with high-quality balls and polished races for a silky smooth spin.
Though admittedly not as idiot-proof as cartridge-type designs, the cup-and-cone setup makes for fine preload adjustment and they're easier to properly service when needed with no special tools required. Moreover, loose ceramic bearings are available from outfits such as CeramicSpeed if you simply can't live without.
You'll have to excuse us if this all sounds like a bit too much praise but the Dura-Ace WH-7850-C24-TL wheels are truly outstanding. Custom hand-built sets can come close in several areas but we can't think of one that can go toe-to-toe across the board and also offers proper Road Tubeless compatibility.
Though the Dura-Ace wheels may not be the '-est' of anything, they're a brilliant balance of light weight, stiffness, build quality and ride quality, and should be considered near the top of the list for anyone looking for a single high-end do-all road wheelset. Excellent work, Shimano.
Superb ride quality, outstanding stiffness, Road Tubeless compatibility and excellent durability - what's not to like?
