An aero bottle cage is a device that holds a water bottle on a bike and has an aerodynamic shape that reduces drag. The term aero bottle cage comes from combining the words aero and bottle cage.
Aero bottle cages typically have features such as:
- Smooth and curved surfaces that minimize air resistance and turbulence.
- Narrow and elongated profiles that align with the frame and reduce the frontal area.
- Lightweight and durable materials such as carbon fiber, aluminum, or plastic.
- Secure and easy access to the bottle from different angles.
Aero bottle cages are used by cyclists who want to optimize their hydration and performance without compromising their aerodynamics. They are especially useful for long-distance events such as triathlons, gran fondos, and endurance races.
Some examples of aero bottle cages are the Elite Crono CX, the Profile Design Aero HC, and the XLAB Aero TT.
