Description:  
Great Used condition! This bike is ready for immediate use. Just passed our multipoint inspection, everything is tuned up and ready to ride. Pictures are the actual bike you will get, not stock photos! Bike is in great Shape for a 70's track bike.It has never been ridden!   This was a Shimano Show bike We purchased it from a former Shimano employee that ran the Neutral service team for Shimano. This is the Ultra-ultra rare NOS Dura-Ace Pitch 10 track groupset, including special 36-hole, high-flange hubs and rear cog, BB and crank with dark anodized Pitch 10 chainring, and ultra rare 10mm pitch chain. Paint is excellent and no decals were ever used.   In 1973 Shimano decided to “reinvent the wheel” and dropped the universally accepted 1/2” pitch and replaced it with 10mm pitch. Their purpose was the 20% weight reduction due to the reduced size of the drivetrain. Their thinking was flawed as all other components remained full size and the weight reduction was minimal. This was further limited by a heavier-than-normal chain.  Never the less, Shimano had some success with a professional World Championship in Match Sprint in 1975 using this system. A prototype multi-gear Road system was built but not developed.
