Beta 45 Bottle Carrier｜ Kitchen & Dining Supplies

The TriRig Beta is a streamlined rear-mounted bottle carrier designed for compatibility with any seatpost using 10mm thru-rail hardware. It’s the perfect solution for riders using bikes like the Cervelo P5/P Series, Scott Plasma, Factor Slick, Ventum Tempus, and many others. With a focus on simplicity and functionality, Beta is a beautiful combination of elegant design and efficient hydration.
Secured with just two M5 button head bolts, the Beta can be adjusted independently of saddle position, allowing one bottle to be mounted directly behind the saddle or two bottles side-by-side. Its low-profile design ensures that the bottles remain in the aero shadow of the rider, delivering a drag-neutral hydration solution.
Beta comes in three configurations:

Beta 45: Positions bottles at a 45-degree angle for a more aggressive setup with less frontal area. Can hold 1 or 2 bottles.

Beta 63: Holds bottles at a 63-degree angle for easier access while riding. Can hold 1 or 2 bottles.

Beta One: Fully adjustable height and tilt. Can hold 1, 2, or 3 bottles.

All versions allow you to adjust the carrier to sit close to the saddle or further back to make room for a saddle bag, all while keeping the setup sleek and aero. The Beta also includes a titanium saddle rail and all necessary mounting hardware.
