BTA Mount for Giant Trinity & Liv Avow Disc (2025): CNC Performance & Modularity

The original Giant Trinity and Liv Avow cockpits are aerodynamic marvels, but their architecture imposes extreme mechanical constraints. The mounting screws not only support your accessories: they hold the very structure of your cockpit under the full weight of your body.

To secure this ultra-critical area, RocketTT has developed a custom hybrid interface. A hidden cast part ensures your safety, topped with a modular system for your watts.

🔩 Hidden Engineering: 7mm 7075-T6 Aluminum Plate

Forget plastic inserts or thin plates. Our intermediate part is CNC machined from a solid block of 7mm thick 7075-T6 Aluminum (aerospace grade).

• Central Structural Role: This plate bolts directly to the original cockpit. It absorbs the shear and compression forces when you push hard on the extensions or hit a pothole at 45 km/h.

• Absolute Security: By stiffening the central anchor, it eliminates play, mechanical vibrations, and secures your entire cockpit. Once installed, it is completely invisible, but it changes everything.

🧩 Direct Fixing & PAHT-CF Modularity

The aluminum plate integrates two specific threads on the top. This is the anchor point for your setup:

1. The Aero Spacer (PAHT-CF): It screws directly into the two holes in the aluminum plate. Printed in industrial Carbon-Nylon and annealed for 4 hours, this spacer allows you to adjust your stack to free up space for your hands while remaining perfectly streamlined.

2. The VFLOW System: Install your nutrition support (single or double bottle) and our aero cone to smooth the airflow between your arms.
