Measurably faster.\u003c\/h2\u003e\u003cp\u003eBehind-the-saddle hydration has become the pro-field standard — every serious tri and TT setup now runs two bottles behind the saddle. The question is how they're mounted. Most systems put the bottles close together. AeroGain mounts them wide apart, in a V-formation, and in velodrome population testing that spacing measured \u003cstrong\u003e1–4 W faster than close-together mounting\u003c\/strong\u003e (n=17 athletes, 45 km\/h, 0° yaw).

When bottles are mounted close together, their wakes overlap — each bottle reduces the benefit the other provides. Opening them into a wide V lets each bottle work independently. The physics is straightforward; most systems don't exploit it because wider spacing is harder to engineer securely.\u003c\/p\u003e\u003ch3\u003eWhat's in this category\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAero BTS PRO system\u003c\/strong\u003e — the flagship.

Most systems mount bottles close together — but close-together mounting overlaps the bottles' aerodynamic wakes, reducing the benefit each one contributes. The AeroGain wide V spaces them further apart so each bottle fills the low-pressure zone independently.
