The Supersonic J5 BTA is specifically designed to integrate with the J5 Bracket featured on the new T+ Carbon Aerobar Systems. Building the BTA mount into the bracket system streamlines the cockpit providing improved performance while the bolt on mount stays secure on the roughest of roads. Moving the system away from extensions opens up hand positions and works with the shortest.
