Hydra Carbon Aero Bottle 700ml/24oz: The Cleanest BTA Hydration Upgrade for Triathletes Security Strap Included for rough roads Meet Hydra, TriRig’s purpose-built BTA (between-the-arms) hydration bottle designed to keep your front-end setup fast, tidy, and race-ready. Whether you’re dialing in your cockpit for long trainer rides or race day execution, Hydra brings aero-minded simplicity to the place you hydrate most. At the core is a carbon fiber cage that delivers a secure hold with a premium, lightweight feel—built specifically for front hydration where stability and easy access matter. Hydra is also designed to integrate seamlessly with TriRig’s BTA ecosystem: it’s best paired with the BTA Riser or BTA Elevator to fine-tune bottle position, improve reach, and keep your cockpit looking dialed. TriRig Hydra Dimensions Side Profile Length: 291 mm Front Height: 84 mm Rear Height: 60 mm Top Profile Front Width: 38 mm Rear Width: 45 mm Capacity Volume: 700 ml Hydra ships as a complete kit, including a straw, bite piece, and extra replacement hardware, so you can build your setup once and keep it running smoothly season after season. And because it mounts anywhere you can run a standard bottle cage, Hydra is easy to add to nearly any tri bike or aero bar configuration—no weird proprietary headache. If you want a cleaner cockpit, easier fueling, and a more intentional BTA setup, Hydra Carbon Aero Bottle is the upgrade that makes your hydration feel as fast as the rest of your bike.
