Description
Designed as a fast road or gravel option, Cannondale’s HollowGram R45 Disc Front Wheel is strong, reliable and aerodynamic. The 45mm deep blunt profile aids its passage through the air at speed whilst the 32mm external width helps smooth airflow over the tyre’s junction with the rim when using a road tyre. If wider gravel rubber is fitted, then the width adds extra support to the sidewall when cornering by keeping the tyre’s profile more stable.
The rim is tubeless-ready, giving easy access to the many benefits of use without an inner tube, especially off-road. Tubeless running allows lower pressures to be used, giving greater comfort, more grip and fewer punctures and also generates less rolling resistance too, making it quicker all round.
