Our newest and fastest BTA system

Engineered to cut drag where it counts
This upgraded Between/Behind‑The‑Arms (BTA) system positions your bottle exactly where it matters—just behind the elbows or tucked close to the chest—delivering up to 10 W of aerodynamic gains at 45 km/h. The added nose-cone provides an added drag reduction compared to our previous designs.

Performance-centric design
Designed to seamlessly clamp onto standard pad bridges and aero bars, the clean, integrated look matches a minimalist cockpit, while offering multi‑angle spacers (0°, 10°, 15°, 20°) for precise setup. Pick the spacer that mirrors your extension angle, ensuring your bottle is perfectly horizontal. (See video below on how to gauge compatibility, and how to choose the right angle).

Modular, customizable, and race‑ready
– Choose your height and bolt‑spacing (medium/wide/extra‑wide).
– Fits most tri‑bar ecosystems
– Durable build, sleek matte black finish—minimalist outside, maximum race‑mode inside.

Why its faster

By closing the gap between the arms and the chest, the AeroGain BTA system guides more air around your whole body, reducing your overall Aerodynamic drag significantly, making you go faster for the same power output.

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.
