Cannondale Hollowgram 45 SL KNOT Carbon Wheelset

The Cannondale KNØT 45 wheels are among the absolute fastest wheels in the world, producing less drag across the entire yaw spectrum than the best competing offerings. Even more impressively, they are designed specifically for higher volume tyres (26mm and up), allowing them to deliver that aero advantage with all the comfort, grip, and rolling resistance benefits larger tyres can offer.

• 45mm profile depth - perfect & ideal for flying over alpine passes and through flat land.

• 21mm internal width - increases effective tyre volume. On these wheels, a 23c tyre measures over 26mm wide, and a 25c over 28mm wide. Larger tyres allow for lower air pressure, more comfort, and better grip.

• Huge 32mm rim width - helps smooth airflow from a large tyre (26+mm), which in turn is held softer against the rim, reducing air resistance. This is otherwise only possible with disc wheels. Optimized for 23c (26mm) tyres, but unlike other wheels, the KNØT 45 design has minimal change with even larger tyres, allowing the rider to achieve more without significant aero loss.
