The Syncros Capital SL Aero wheels, with their curious carbon monocoque design, are on the slicing fringe of highway bike wheel growth, a superlight resolution for riders ready to take a position closely of their quest for velocity.
They’re a distant descendant of Syncros’s Silverton mtb wheels, the Scott-owned model’s first one-piece carbon-fibre wheelset launched again in 2018. These off-road hoops had been ridden to victory by Tom Pidcock on the Tokyo Olympics, and carried Nino Schurter to a number of World Cup victories, so the Capitals include a tremendous pedigree.
Basically, every wheel – rims, hubs, spokes and all – is constructed as a single unit, a way Syncros says produces a “one-piece carbon wheel system that’s lighter, stronger and extra responsive”. We’ll see.
Syncros Capital SL Aero wheels building
Syncros’s designers’ priorities started with low weight and inertia, shifting on to aerodynamics earlier than concentrating on dealing with, really feel and rolling resistance.
The one-piece building addresses just a few of these priorities, minimising the variety of parts whereas making them lighter, stiffer and extra aerodynamic.

To create the only unit, the rim’s carbon fibre is laid up by hand, a latticework of carbon spokes is sandwiched in between and a bearing tube, which carries the DT Swiss hub internals, is bonded into place. The spokes lack nipples, or any form of adjustability, which is okay as a result of they’re set exactly throughout manufacture.
Throughout product growth, Syncros labored carefully with German tyre maker Schwalbe, which created the Professional One Aero to deliver out the very best efficiency qualities of those wheels. The Capital SLs are each tubeless and hookless, with 28mm stated to be the optimum tyre dimension for each consolation and aerodynamic effectivity.
Speaking of aero, Syncros claims the Capitals wheels are 7% sooner than any of the quickest competitors: DT Swiss ARC 1100 62mm, Campagnolo Bora Extremely WTO 60 and Zipp’s 454 NSW and 404 Firecrest. Of that assortment, the DT Swiss wheels are the lightest at 1,381g – nonetheless no match for the 1,290g Syncros. The Capitals are bought as being appropriate as a gravel wheel too, capable of deal with tyres as much as 50mm broad, although I’d hesitate to take such an costly set of hoops onto something remotely rocky.
These wheels are removed from a price providing, coming in at a really expensive £3,830/$4,599.98.
Syncros Capital SL Aero wheels trip high quality
I used the wheels on a Large Defy Superior SL0 I used to be testing, transferring the large 10-36 cassette from the unique 30mm-deep Cadex wheels.
So, are they sooner than the inventory wheels on my bike? Sure, with out reservation. Each comparable trip on the Syncros wheels was sooner than on the inventory Cadex wheels. One trip used eight watts much less and was 2.4kph sooner than one other with the inventory wheels on an analogous route in nearly similar circumstances. All rides on the Capitals used much less energy than rides on the inventory wheels at comparable speeds.

On sooner rides the place the aerodynamics might actually make a distinction, the facility saving was even larger. So, racers travelling at race speeds stand to get probably the most out of those wheels.
Accelerating out of corners wasn’t fairly like opening the throttle on a bike, however they spin up so rapidly that I couldn’t assist however smile. And do it once more. And once more. Up hills and on the flat, as soon as in control it’s straightforward to remain there – it feels such as you’re being sucked alongside, on a regular basis making a scrumptious whooshing sound.
It’s not simply the noise and velocity that make these wheels a delight – the dealing with is elegant. They slice fantastically by means of each curve, they’re really confidence-inspiring, they’re stiff, however not unforgiving, none of that rigidity compromises consolation. And, whereas the bane of all deep-section wheels was crosswind efficiency, the Capitals preserve stability properly. Regardless of intentionally heading out on windy days, the one time I used to be caught out was when a lorry handed too shut.
Are they sooner than the competitors? Nicely, we examined these wheels in real-world circumstances, relatively than in opposition to their rivals in a wind tunnel, so it’s arduous to say whether or not they are surely the world’s quickest, as claimed.
Syncros Capital SL Aero wheels worth and verdict
The Syncros Capital SL Aero wheels don’t simply look nice, they’re mild, quick and secure. In brief, they’re the best-handling wheels I’ve ever used. If we put the worth apart, these distinctive wheels are distinctive.
Nonetheless, for many of us, £3,830/$4,599.98 is a prohibitive sum of money to spend, even when contemplating the crash alternative scheme that brings peace of thoughts ought to the worst occur.
