Here's the Sigma installed on a bike. You can see how the cables are managed quite neatly to keep them out of the wind. But that stem cover can be removed at any time for easy access to the stem cavity or the cables themselves.
The Sigma stem is currently in development, and will soon be available at this link in the TriRig Store.
The TriRig Sigma is the first production stem built to provide superlative aerdynamics, elegant cable management, and integrated centerpull cable routing for aero brakes like our own Omega. This is TriRig's next production project, and it's going to significantly clean up the traditional front end to a degree previously achieved only in the realm of the so-called 'superbikes.'
