- Free worldwide shipping for orders over 200 EUR/235 USD
The ultimate setup
Our newest BTA system combined with out high-sided armrests, for an aerodynamic system with high forearm support, enabling you to stay for longer in your aero position while cutting drag.
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
Performance-centric design
Designed to 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, for a horizontally placed bottle. (See video below detailing how to choose the right angle).
Modular, customizable, and race‑ready

– Fits most tri‑bar ecosystems
– Durable build, sleek matte black finish—minimalist outside, maximum race‑mode inside.
