Aero BTA system spacer kit
- Free worldwide shipping for orders over 200 EUR/235 USD
This is a spacer kit that is compatible with our BTA mount plates, our Aero Cockpit and our Custom Mono Armrest. If you have previously purchased one of our other BTA systems, this will mount on the same base and replace your other spacers.
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 compared to no bottles near the cockpit
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).
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.
