Shimano AX Introduced in 1981, AX parts were perhaps one of the most audacious efforts to redesign modern racing "gear." The aerodynamic-to-the-max effort made the AX truly ahead of its time! Sadly (?) the world was not ready for this futuristric group and after two years of production, the plug was pulled!
