Kappa Under BTA Cage: The Ultimate Grip for Triathlon Hydration
999% of the time the TriRig Cages do not need a bottle strap to help hold on ruff terrain
This cage is designed for holding bottle under the BTA System giving you maximum hold.
Say hello to Kappa, the strongest and most versatile cage on the market, engineered specifically for triathletes. Designed with a singular goal—optimal grip strength—the Kappa Cage prevents bottle launches better than any other option, making it the perfect choice for demanding setups like rear-mounted hydration systems.
Kappa’s solid wrap-around wings ensure that your bottles stay securely in place. There are no aesthetic cutouts that weaken the grip—just pure performance. Made entirely of 3K carbon fiber, Kappa provides superior stiffness and durability, giving you confidence over any terrain.
For front BTA setups, the Kappa Cage excels with its open-wing design, allowing straws to pass through easily. It also features spine relief slots for easy zip-tie mounting—no drilling required. Whether you have a bolt-on BTA mount like those on Alpha aero bars or need a quick zip-tie solution, Kappa adapts effortlessly.
The Kappa Cage combines strength, versatility, and ease of use, making it the go-to choice for triathletes looking for a drag-neutral hydration solution that keeps bottles secure over any course.
