TriRig BTA Sport Kit

TriRig BTA Sport Kit is a between-the-arms hydration bundle for triathlon and time trial bikes. TriRig intends it for dedicated athletes who want better fit, access and aero performance on race day or long training rides. Four TriRig parts come in the box, including a carbon bottle cage.

What's included

• Universal BTA Adapter Plate: a 6mm slab of T6-6061 aluminum with a hard-anodized finish. It installs directly beneath the arm cups and adds a bottle mount to aerobars that have no bolt bosses of their own.
• BTA Elevator: lets you adjust both the height and the tilt of the bottle mount. It is 6061-T6 aluminum with a hard-anodized coating, and its base bolts line up with standard bottle cage bosses.
• Multi-Bottle BTA Rail: machined from 10mm billet T6-6061 aluminum and hard-anodized. It supports one to four bottles or accessories in multiple positions.
• Kappa Cage: full 3K carbon fiber with solid wrap-around wings for a firm grip on the bottle. In BTA setups the open-wing design accommodates a straw, and spine-relief slots allow zip-tie mounting.

Sport Kit versus Starter Kit

The Sport Kit differs from the TriRig BTA Starter Kit in two ways. The plain 80 mm BTA riser becomes the BTA Elevator, so bottle height and tilt can be tuned rather than fixed. The Elevator also pairs with the Multi-Bottle Rail for a one-to-four bottle layout that adapts to race distance. And the Kappa Cage is included, where the Starter Kit leaves the cage to you.
