TriRig Universal BTA Adapter Plate

TriRig Universal BTA Adapter Plate provides a straightforward, highly adaptable foundation for riders who need a Between-the-Arms (BTA) bottle mount on aerobars that lack dedicated bolt bosses. Designed to be installed directly beneath arm cups, this plate creates a stable, ergonomic platform for front-end hydration setups while preserving clean cockpit integration.

Engineered from a solid 6mm slab of T6-6061 aluminum and finished with a durable hard-anodized coating, the Universal BTA Adapter Plate is built for long-term reliability. Standard bottle cage spacing ensures compatibility with nearly all bottle cages, making it easy to configure a personalized hydration system.

The plate also works seamlessly with other TriRig accessories—including Kappa bottle cages, the BTA Riser, and the 3-in-1 Polymount—giving athletes the flexibility to build a front-end setup tailored to their race goals and riding style.
