Brand:TriRig

Code:TRIRIGSIGONE0102

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.

KEY FEATURES

  • Lightweight and Aero Design: The lightest and most aerodynamic stem in the TriRig range, ensuring maximum speed and efficiency.
  • Two-Bolt Adjustability: Adjust or remove your entire aerobar setup with just two bolts for ultimate ease of use.
  • Integrated Cable Management: Simplified routing for both cabled and hydraulic systems, compatible with both rim and disc brakes.
  • Monopost Compatibility Kit: Allows for stack, tilt, and continuous adjustment from -5 to +17.5 degrees.
  • Wide Compatibility: Works with any 22.2mm extensions, including TriRig's Gamma lineup, and fits perfectly with Scoops Arm Cups.


RIDE IT YOUR WAY

Adding the optional Monopost Compatibility Kit takes the system to a whole new level. Just two bolts set your stack, tilt, and lock everything in place.Two bolts to install, two bolts to remove.

LIGHTEST AEROSTEM ON THE MARKET

Sigma Oneis the ultimate solution to any road, tri, or hybrid bicycle. Whether you’re aiming for tri, offroad tri, gravel, century, or hybrid setups,Sigma Onehas you covered like nothing else on the market. In short,Sigma Oneisn’t merely an update ononeof TriRig’s core products. It is the pinnacle of what a triathlon-oriented stem can be.

OPTIMIZED & IMPROVED

Adding the optional Monopost Compatibility Kit takes the system to a whole new level. We took the same technology that makes AlphaOneso special, then ported it to a stacked spacer setup so that it can function onSigma One's stem clamp. Just two bolts set your stack, tilt, and lock everything in place.Two bolts to install, two bolts to remove. Just as on AlphaOne, you get a continuous tilt adjustment range from -5 to +17.5 degrees. Add in the extensions of your preference from our own world-class Gamma lineup, or use any industry-standard 22.2mm extension. Then top it all off with any of our Scoops Arm Cups, and you’re off to the races.

PRACTICAL

In its base configuration,Sigma Oneis both the lightest and the most aero stem we have ever made, while retaining all the best-in-class features from its predecessor. Neat cable management and front brake cable routing are integrated into the design of the stem, but without the need for any fussy internal routing. Just run your cables as normal, then collect them beneath the cable cover and bolt down the top cap to lock everything in place. Both cabled and hydraulic housing fit easily through this routing system, and whether you’re on rim or disc brakes,Sigma Onestill offers the same tidy centerpull routing as every stem we’ve ever made.
