The Cervlo spero-5 GRX RX825 Di2 is built for riders who demand precision and performance across the most demanding gravel terrain, bringing together aerodynamic speed, electronic shifting, and adventure-ready versatility in a single race-caliber platform. With its sleek internal cable routing, integrated aero cockpit, and refined carbon layup, this bike is engineered to cut through wind and rough terrain alike, delivering up to 37 watts of aerodynamic advantage over earlier models.

Paired with Shimanos latest 12-speed GRX RX825 Di2 electronic drivetrain, the spero-5 offers intuitive, lightning-fast shifts and a wide gearing range tailored for gravel racing and endurance exploration. Confident and composed over loose surfaces, the progressive geometry allows for mixed tire setups, matching a narrower front with a wider rear, or equal-width tires for balanced all-terrain handling.

Whether you’re climbing chunky fire roads or descending through tight, technical trail sections, the spero-5 stays stable, fast, and in control.

Whether you’re toeing the start line of a gravel race or riding into the unknown, the spero-5 GRX RX825 Di2 delivers unmatched speed, control, and adaptability for the road less traveled.
