Profile Design Aero HC
The draw: Streamlined, simple and secure fluid source
Profile Design has evolved from its upright aerobar hydration systems into this horizontally oriented one. Improved aerodynamics is the objective, and Profile claims a savings equivalent to 10 seconds over an Olympic-distance bike leg. It uses a standard water bottle cage to hold the bottle, meaning a rider could conceivably use a round bottle if he wanted to. The bottle is refillable on the fly, and the small flip cap virtually eliminates splash-back. An integrated mount behind the bottle can carry a computer, but reading data can be a challenge since it sits far rearward.
