Tri Rig Beta Bottle Carrier

Beta Rear-Mounted Bottle Carrier: Sleek Hydration for Any Seatpost

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 P2/P3 (rim brake versions), Scott Plasma 5, and many others. With a focus on simplicity and functionality, Beta is a beautiful combination of elegant design and efficient hydration.  Can be used on almost any saddle with the Beta Bike saddle bracket.

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 two configurations:

• Beta 45: Positions bottles at a 45-degree angle for a more aggressive setup with less frontal area.

• Beta 63: Holds bottles at a 63-degree angle for easier access while riding.

Both 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.
