TriRig Kappa Saddle Cage (FULL CARBON 2.6mm)

Kappa Saddle Cage: Best-in-Class Rear Hydration System

Full Solid Carbon 2.6mm Strongest on the market.

The Kappa Saddle Cage is engineered to deliver unbeatable bottle retention and ease of use for rear-mounted hydration systems, making it the go-to choice for triathletes and endurance cyclists. Building on the proven strengths of the original Kappa cage, this upgraded design inverts the geometry for behind-the-saddle hydration, ensuring both secure retention and fast access when it matters most.

Instead of a standard retention tab above the bottle, the Kappa Saddle Cage uses a unique split-tab design at the end of each wing. Combined with ultra-thick cage walls, zip-tie mounting slots, and a solid no-cutout structure, this innovation makes the Kappa Saddle Cage one of the strongest and most reliable cycling bottle cages for rear hydration.

Designed to handle rough roads and race conditions, the Kappa Saddle Cage eliminates the need for straps or cords and keeps bottles locked in place over any terrain. For triathlon and Ironman athletes, it’s the ultimate rear hydration solution — secure, aerodynamic, and hassle-free.
