TriRig BTA Elevator Between-the-Arms Bottle Mounts

The TriRig BTA Elevator Between-the-Arms Bottle Mount is a versatile hydration mounting solution designed to help fine-tune bottle position on aero and triathlon cockpits. It allows riders to adjust both the height and tilt of a BTA bottle setup for improved accessibility, ergonomics, and front-end organisation.
Compatible with standard bottle cage spacing, the BTA Elevator can be used with a single bottle cage or paired with TriRig’s Multi-Bottle Rail for more complex hydration and accessory configurations. Built from durable T6-6061 aluminium with a hard-anodised finish, it offers a strong, adjustable platform for triathlon, time trial, and long-distance cycling setups.
