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.

The Disc 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.

The Disc 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.

VERDICT: This is an impressive wheelset: serious bang for buck - 88%"
