TriRig BTA Pro Kit

TriRig BTA Pro Kit is a fully integrated between-the-arms hydration system engineered for serious triathletes and time trialists who demand aerodynamic efficiency without compromising functionality. Designed to mount cleanly between aero extensions, the BTA Pro Kit provides a stable, low-drag hydration solution that keeps fluids accessible while preserving your optimal race position.

Hydration placement is critical in long-course racing. A poorly positioned bottle can disrupt airflow and force awkward hand movements. The BTA Pro Kit addresses both concerns with a precision-machined mounting structure that positions your bottle directly in the rider’s aerodynamic envelope. The result is a cleaner cockpit profile and intuitive access to hydration without breaking position.

Aerodynamic Integration

The TriRig BTA Pro Kit is designed with aero performance in mind. Its streamlined mounting hardware minimizes frontal area and blends naturally with modern aero extension setups. By placing hydration between the arms, airflow remains smooth around the cockpit — a configuration widely recognized for reducing drag compared to traditional down-tube mounts.

The rigid mounting platform ensures stability over rough pavement and high-speed conditions. No rattling, no bouncing — just a secure, race-ready solution that keeps your bottle exactly where you need it.

Premium Construction

Crafted with high-end materials and precision manufacturing, the BTA Pro Kit reflects TriRig’s focus on performance-driven design. The structure is engineered for strength and stiffness while maintaining a lightweight profile appropriate for elite-level competition. Hardware and mounting interfaces are designed to integrate cleanly with a wide range of aero bar configurations.

This system supports both training and race-day setups, offering the adjustability required to fine-tune bottle height and fore-aft positioning between extensions. That flexibility allows athletes to optimize both aerodynamics and comfort.
