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 futuristic group and after two years of production, the plug was pulled!

AX components were unusual in many ways...


SANTE Components
Introduced after the Aero style components in the mid 1980s, Sante was positioned below
Dura Ace and above Ultegra 600.  This group was intended to be a stylish semi Pro level package.


DEORE Touring Components
(Before they used that name for Mountain Bike parts!)
A unusual blend of new design and traditional French cues...
