Shimano Dura-Ace 7900 Aero Build Kit

SHIMANO DURA-ACE 10 TRACK GROUPSET very slightly used. Shimano launched the minaturised track Dura-Ace set in the mid 70s and it continued to be catalogued into the 1980s. They are really quite rare though spare sprockets and chainrings turn up on Ebay reasonably frequently. Here I have a complete DA 10mm pitch drivetrain with two sprockets, 15T and 16T – this gives gears of 78in and 84in approximately. Cranks are 165mm with a 48T chainring. Chain is 45in long (about 114 links). Hubs are the special DA 10, with 36H drilling, rear is 120mm OLD and front 100mm OLD. Comes complete with Italian threaded BB.
