Sigma One: The Pinnacle of Aero Stem Design
The TriRig Sigma One is an advanced carbon aero stem, designed to deliver unmatched integration, aerodynamic efficiency, and versatility for road, triathlon, or hybrid bike setups. Born from the innovative Alpha One aerobar, Sigma One is the only stem on the market that accepts a stack of mono risers, integrating seamlessly with the tilting Dragonfly cup mount system. This unique design allows you to adjust or remove an entire aerobar setup with just two bolts, offering unparalleled convenience.
In its base form, Sigma One is both the lightest and most aerodynamic stem in TriRig's lineup. It features integrated cable management for both cable and hydraulic systems, and front brake cable routing is built into the design without the need for complicated internal routing. This ensures a clean, streamlined look while maintaining full functionality for both rim and disc brakes.
Whether you're aiming to optimize your triathlon performance or refine your road bike setup, Sigma One provides an ideal solution with its unmatched performance and flexibility. Take your ride to the next level with this advanced carbon aero stem.
