When we first introduced the original Sigma, it was a revolution - the first stem on the market with integrated cable management. Since then it's been imitated by many others, but never surpassed ... until now. The carbon-fiber Sigma X is the next generation in clean stem design, borrowing technology from our Alpha X aerobar, and porting it to an aero stem. It comes complete with our aero-matched stem spacers, ultra-low-stack dust cap (1mm), and more.
