Parcours Disc² Full Carbon Rear Wheel (Disc Brake)

Our all-new Disc² rear wheel is perfect for use in both time trials and triathlons. The Disc² is the first full carbon rear disc wheel that is truly optimised for a wider tyre, delivering all the associated benefits with zero compromise.

As part of the Monuments range, the Disc² comes with a lifetime warranty.

The Disc² is the first disc wheel that is designed from the ground up to be fitted with a 28mm tyre and testing has shown no aerodynamic penalty up to a 30mm tyre size. The 22.5mm internal rim width makes this the widest disc wheel currently available. A hooked rim design maintains the widest possible tyre compatibility.

Tubeless-ready, this allows a rider to run a wider tyre at a lower pressure and minimise the physiological toll of racing. Stay fresher for longer and really push your race day performance to the max.

The Disc² is available as a single wheel option or paired with our Chrono Max front wheel to offer the ultimate race day setup. For the perfect level of flexibility on race day, it is also available with the Chrono front wheel.

Aerodynamic Performance & Race Optimization

The Disc² wheel is engineered to deliver elite-level aerodynamic efficiency during high-speed racing. Its full carbon disc structure minimizes air turbulence and reduces drag, helping riders maintain higher speeds with less effort. The wide rim profile works seamlessly with modern wider tyres, improving airflow around the tyre-wheel interface. This results in better aerodynamic stability even in crosswinds. The design also allows riders to run lower tyre pressures when using tubeless setups, reducing rolling resistance and improving comfort during long races. These advantages help athletes conserve energy and maintain peak performance throughout demanding time trial and triathlon events.
