TriRig Kappa Cage

The TriRig Kappa Cage is engineered with a singular purpose: to deliver the most secure, confidence-inspiring bottle retention available for triathlon and time trial racing. Built for athletes who demand absolute reliability—especially in rear-mount hydration setups where bottle ejection is common—the Kappa prioritizes grip strength above all else. Its wrap-around carbon wings hold bottles firmly over rough pavement, high-speed descents, and technical courses, making it an ideal match for TriRig’s Beta rear carrier or any saddle-mounted hydration system. Constructed entirely from robust 3K carbon fiber, the Kappa Cage eliminates aesthetic cutouts or flex points that weaken grip on traditional cages. Instead, its continuous carbon architecture maintains stiffness, durability, and consistent pressure on the bottle. For athletes running BTA (between-the-arms) setups, the open-wing design accommodates straws with ease and offers drag-neutral integration at the front of the bike. Spine-relief slots allow zip-tie mounting without drilling, giving riders flexibility whether they use a bolt-on Alpha BTA mount or need a fast, adaptable tie-on configuration. From long-course triathlons to high-intensity TTs, the Kappa Cage delivers secure hydration access without compromising aerodynamic performance. Its blend of strength, versatility, and rider-focused design makes it a standout upgrade for any performance-driven triathlon cockpit.
