The new one-piece wheel, the Syncros Capital SL, weighs 1170 g at 40 mm depth and 1290 g at 60 mm depth, comparable to the best lightweight wheels. At the same time, when fitted with the new Schwalbe Pro One aero tires, which Syncros calls "System for Speed," aero drag is reduced by 7%.

Syncros, a subsidiary of Scott Sports, uses a one-piece carbon construction on its new wheels that integrates 16 carbon spokes and hookless bead rims. The design is similar to the recently released 12-spoke carbon wheels of the Colima MCC.

The brand claims that its patented manufacturing process allows for a consistently high tension in the carbon spokes. Basically, Syncros says that by incorporating the center portion of the hub body after curing, the spokes are pushed outward, resulting in precisely defined spoke tension.

In addition to weight savings, the reduced mass of the rim section also reduces rotational inertia, which Synkros says is 20% lower than that of a conventional spoked carbon-rimmed wheel. As a result, the spokes have more tension and the wheel spins faster during acceleration, according to the company.

To improve the handling feel of the new Syncros Capital SL wheels, Syncros says it has focused on optimizing wheel stiffness by utilizing its structural processes. The carbon spokes are 35% stronger than steel spokes and run from one side of the rim across the hub flange to the other side, and are braided at intersections for improved torsional stiffness, according to the company.

The rim has a hookless construction, which, according to Syncros, provides a smoother transition from the tire to the rim and reduces aerodynamic drag. It also improves impact protection, reduces the risk of pinch flats, increases rim strength, and is lighter than hooked beads, according to the company. The maximum tire pressure is reported to be 5 bar/72 psi.

Syncros is not only focusing on wheel stiffness, but has also brought the new wheelset into the wind tunnel to refine the aerodynamics, resulting in a 7% reduction in drag over a range of yaw angles compared to benchmark wheels (unspecified).

Schwalbe viewed the wheel and tire as a system and developed the new 28mm Pro One Aero tire with the wheel. This tire has different sizes, tread depths, and patterns on the front and rear to balance aerodynamics, rolling resistance, grip, and durability.

The rims are ETRTO compliant and have a wide 25 mm inner width that was optimized to balance aerodynamics and rolling resistance.

According to Syncros' testing, the new wheels and tires are faster and offer optimal handling compared to competitive wheels with narrower tires.

The new Schwalbe Pro One Aero tires are only 28 mm wide and offer lower rolling resistance and a larger sail area than narrower tires. This is especially important for the front wheels, which are in the airflow more than the rear wheels.

Schwalbe therefore states that the front tires were developed to provide an optimized aerodynamic profile for wider, modern rims. The rear tires, on the other hand, are designed to reduce rolling resistance and improve durability.

Schwalbe claims that the new front tire reduces aerodynamic drag by 20% at 45 km/h compared to the same width Pro One TT tire. The new tire also incorporates the RaceGuard puncture protection layer to provide enhanced protection against punctures, which the Pro One TT tire did not have.

Since lightweight is especially important on climbs, Syncros has announced that Romain Bardet and the DSM-Filmenig team will be using the new Capital SL wheels in tomorrow's Tour de France climb time trial.

"We are delighted to extend our partnership with Syncros. We worked intensively with Syncros engineers who share the same overall approach to aerodynamics. The result is a great TT wheel that blends perfectly with the other aerodynamic elements. I can't wait to race with the Syncros TT wheels from tomorrow onwards," said Narelle Neumann, Head of Science at Team DSM-Filmenig.

If the Syncros Capital SL wheelset is too esoteric for you, there are also conventional spoke types available with the same 40mm and 60mm rim profiles. Both come with Shimano 11 speed or SRAM XDR freehubs.

The new wheelsets also come with a 2-year legal warranty and a 3-year crash replacement program in case of an emergency.

Team DSM-Filmenig riders will use the Syncros Capital SL wheelset in the time trial. And also in tomorrow's 22km time trial stage of the Tour de France. Syncros has been supplying the team with saddles, seatposts, cockpits, and other components since 2021. However, under the new partnership, men's and women's teams will compete in the time trial on Scott Plasma time trial bikes equipped with Capital SL disc rear wheels and Capital SL 60mm front wheels. The disc wheel weighs 970 grams and the 60mm front wheel weighs 590 grams.

Pascal Ducrot, Vice President of Scott Sport, said, "Today we announced the extension of our sponsorship of the time trial wheels and further the partnership with Team DSM-Filmenig. We are excited to further develop our partnership with Team DSM-Filmenig. The innovative Capital SL wheels will be of great benefit to the team and we look forward to working with them in the years to come.
