Our most versatile BTA system yet
Engineered for dual hydration and optimal positioning

The Double Bottle BTA System v2 is built for flexibility and performance. Its redesigned top section enables highly versatile bottle positioning—whether you run a single bottle or a dual-bottle setup. The top bottle can be positioned forward between the arms for maximum aero efficiency, or further back, closer to the rider’s chest, depending on your preference and fit.

The system integrates seamlessly with standard aero cockpits and is fully compatible with popular hydration systems such as the XLAB Torpedo.

Performance-focused adjustability
Multi-angle spacers (0°, 10°, 15°, 20°, 25°, 30°) allow you to precisely match your extension angle, ensuring your bottles remain perfectly horizontal. The result is a clean, dialed setup that works with your position—not against it.

Modular, customizable, race-ready
– Mount one or two bottles depending on your race strategy
– Adjustable height and bolt spacing (medium / wide / extra-wide)
– Compatible with most tri-bar systems
– Durable construction with a clean matte black finish

Why it’s faster
By optimizing bottle placement between the arms, the system helps streamline airflow through your cockpit. Whether running one or two bottles, it reduces turbulence and supports a more efficient aerodynamic profile—helping you maintain higher speeds at the same power output.

Includes

1 BTA mounting plate.
1 Angled spacer

The AeroGain experience

This isn’t just an upgrade — it’s a statement.

The AeroGain cockpit was built because we were tired of compromising. Too many setups sacrificed either comfort, control, or aero. So we created the system we always wanted — and now we ride it.

Why Choose AeroGain?

We’ve spent hours in the pain cave, the races where comfort slipped, and the long rides where the gear just didn’t work. That’s why AeroGain was built — not to look fast, but to be fast. Every product we make is tested by real triathletes, in real race conditions, before it ever reaches you.

We Built It. They Raced It. Here's What They Say.

★★★★★
The AeroGain mono arm rest completely changed my position. It gave me the stability and support I needed to hold aero for longer — and I felt the difference straight away. It’s honestly one of the best upgrades I’ve made to my setup.
