Aero hydration system

For the
podium.

A transparent, dimpled 750 ml bottle made for the cage already on your bike. Less drag than a smooth bottle of the same volume, without a proprietary mount.

01 / Universal fit

Your cage.
Any course.

Road, gravel or time trial, the Ottr Bottle sits in the cage already bolted to the frame. A proprietary system can go further on drag, but Ottr chose the cage you already own.

Built around
the bottle.

The form is familiar where it meets your hand and cage. The surface changes where it meets the air.

03 / Technical data

Less drag.
Real numbers.

0.75W

At 40 km/h, the dimpled bottle needed 9.58 W to overcome aerodynamic drag, against 10.33 W for a smooth 750 ml bottle of the same volume. That is 7.3 per cent less drag power.
