TriRig Beta 45 Bottle Carrier

The TriRig Beta 45 Bottle Carrier offers an aerodynamic and elegant hydration solution for triathletes and time‑cruisers. Designed to mount securely behind the saddle at a 45° angle, it reduces frontal area and stays tucked in the rider’s aero shadow for minimal drag.

Its simple yet ingenious design—featuring a titanium thru‑rail and just two M5 button‑head bolts—allows independent adjustment of one or two bottles without moving the saddle. Compatible with any seatpost using 10 mm thru‑rail hardware, it integrates seamlessly with TriRig’s Kappa cages for maximum bottle retention and stability.
