Perform at your best, with the Cannondale Hollowgram Si Carbon Clincher Wheelset.

Constructed with the same Hollowgram technology as Cannondale use in their crank arms, this full carbon wheelset is incredibly strong, rigid and weighs a sublime 1480 grams without skewers. These clinchers offer low rolling resistance, increased comfort and excellent puncture protection, and the mid-depth 35mm rim provides the perfect balance of aerodynamics and stability.

Also includes two quick-release skewers.

Cannondale Hollowgram Si Carbon Clincher Wheelset

Bridging the gap between efficiency and performance, the Cannondale Hollowgram Si Carbon Clincher Wheelset weighs an impressive 1480 grams (without quick-release skewers), offering next-level stiffness, efficiency and braking predictability. Cannondale's own Hollowgram hubs ensure smooth rolling and fast engagement.

At 35mm deep, the rims of the Hollowgram Si Wheelset sit beautifully between aerodynamic and responsive, providing the handling of shallow depth rims but still offering improved aerodynamic efficiency out on the road.

These wheels are subtly emblazoned with the Cannondale logo, offering great aesthetics to complement any bike setup.
