Introducing the groundbreaking Precision C21™ Aero Disc. Featuring featherlight construction, a design focused on responsive handling, and exceptional aero prowess, the C21 is the perfect upgrade for your triathlon/TT bike.
Razor-Sharp Precision
The carbon disc doesn't just ensure aerodynamic advantages; it also boasts exceptional radial and lateral stiffness. With unified UD fiber direction in the primary carbon layers, the C21™ provides quick and responsive acceleration with every pedal stroke. This translates to snappy performance when you’re putting the power down against the clock.
Lighter than Tubular Discs
The C21™ uses a sandwich-like construction of foam and carbon that lowers wheel weight to 950g (paintless). This means it’s ~200g lighter on average than many other tubeless disc wheels and even some tubular discs on the market, at a more cost-effective price.
Stability at Speed
In the high-paced arena of time trials and triathlons, speeds often exceed 40 km/h, and precision is absolutely everything. Wobbles or imbalances in the wheel are immediately noticeable and take precious energy from the rider to counteract. To ensure your race experience remains uncompromised, we conduct rigorous dynamic speed balance testing in-house on every Precision C21™ disc wheel, simulating speeds of up to 60 km/h. This means you can trust that every wheel that arrives at your doorstep is ready to perform at the highest level.
Tech
01 Tubeless capable
The Precision-C21™ is compatible with both clincher and tubeless tires. The modern 21mm inner width suits tires of 23mm and wider.
02 Valve Spacer
The C21™ is equipped with a specially designed carbon spacer to fit within the valve collar firmly and effortlessly.
03 Valve Hole Cover
The C21™ is also equipped with a valve cover sticker to cover valve cutouts to ensure your wheel is race-ready. The cover is easily removable for tire inflation.
04 Paintless or Piano Black
The Precision C21™ is available in either paintless (no rim coat) or piano black (glossy) finishes. We also offer a selection of custom decals if you’d like to personalize your wheel experience.
