Sigma One Carbon Aero Stem

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.

On every order you'll receive tracking as soon as your order ships. We encourage you to follow along with shipping updates with the carrier you've selected.

International shipping. What to expect.

We ship anywhere in the world. Typically international shipping goes smoothly with a few caveats.

You'll be responsible for Duties/Taxes when the order arrives in your country. Typically you'll be contacted by the carrier to fulfill their needs to have your order delivered. Often times that means you'll pay a fee / tax.

Imported product must typically clear customs. This process is completely out of our control and can take anywhere from a matter of hours, to a matter of weeks. What's most helpful for you is to keep yourself informed of tracking updates.

You'll receive tracking when your order ships from our facility. We have as much information as you do when it comes to tracking.

We also highly encourage our International customers to purchase shipping insurance at checkout. Because of the unpredictable nature of shipping overseas, its a small cost for peace of mind knowing you'll receive your order.

Shipping Insurance?

We highly encourage our international customers to purchase Shipping Insurance at checkout. A small price to pay for piece of mind. If something happens to your order in transit, you'll be able to file a claim and undoubtedly receive your order.
