It is hard to believe that this bike is in fact as old as it is. The Tange Aero tubing was certainly ahead of its time… aero right down to the seat post tube. This bicycle is a real engineering marvel and it shows just what Panasonic was capable of during the early eighties. The frame shown here appears to have been built in May of 1982. Special thanks to Robin Bennett for allowing me to photograph his bicycle for use on this web site.

The frame isn’t the only thing special about the AR-6000. This bike also featured the Dura Ace AX component group. Dura-Ace AX components were introduced at the International Cycle Show in Cologne, Germany in 1980. According to the Shimano web site, the group was based on an innovative new aerodynamic design theme. Through the use of the bicycle industry’s first wind tunnel, Shimano engineers developed a component series with 20% less drag than contemporary designs. Shimano’s quest to produce the best performance products available is evident.
The other most obvious feature, other than the slight profile, is the interesting cable holder on the back of the derailleur. This was designed to take the bare cable, without housing, and feed it to the pinch bolt. Many bikes of this era had a cable guide mounted on the seat tube just above the bottom bracket shell. The bare cable would run from the down tube shifter under the guide and straight to the rear derailleur. No housing needed. A creative solution to cable drag!
