Cervelo WB01 Aero Bottle/Cage Assembly

The Cervelo WB01 Aero Bottle/Cage Assembly is designed to integrate seamlessly with Cervelo’s aerodynamic road platforms, offering a hydration solution that complements the bike’s wind-cheating frame design. Engineered specifically to reduce aerodynamic drag while maintaining secure bottle retention, the WB01 system provides riders with an efficient way to carry hydration without disrupting airflow around the frame.

Unlike standard round water bottles and traditional cages, the WB01 Aero Bottle/Cage Assembly is shaped to match the aerodynamic profiles used on Cervelo performance road bikes. The bottle’s streamlined form helps guide airflow smoothly around the down tube, minimizing turbulence and preserving the aerodynamic advantages built into modern race frames.

The system consists of a purpose-built aero bottle paired with a precisely matched cage that securely holds the bottle during aggressive riding conditions. Whether sprinting, descending, or riding rough pavement, the cage is engineered to keep the bottle firmly in place while still allowing easy access for quick hydration during training rides and races.

The aerodynamic bottle design is also optimized for practical everyday use. The shape fits naturally within the rider’s reach, allowing for smooth bottle insertion and removal without requiring excessive force or awkward hand positioning. This thoughtful design ensures that riders can stay hydrated without compromising focus or control while riding at speed.

Durability and reliability are central to the WB01’s design. The cage is constructed to withstand the vibrations and stresses associated with performance road riding, ensuring consistent bottle retention across long training rides and demanding race environments.
