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.

Hi, Do you have information on your track disc wheel options and their cost? Is it possible to have the C21 rear disc with a track hub? Many thanks, Oli
