The TriRig Kappa Bottle Cage is built to deliver excellent grip and reliability for triathletes and time trialists. Made entirely from 3K carbon fiber, it offers exceptional stiffness and durability without unnecessary cutouts that compromise strength. The solid wrap-around wings lock bottles firmly in place, preventing launches on rough roads or during aggressive accelerations, making it especially effective for rear-mounted setups like the Beta carrier. For front BTA configurations, the open-wing design allows straws to pass through cleanly, while spine relief slots enable easy zip-tie mounting when bolt-on options arent available. The Kappa Cage combines lightweight construction, versatile mounting options, and best-in-class retention to ensure your bottles stay exactly where you need them.
