Shimano 600 AX FC-6300 Crank Arms: 170mm - Dyna Drive - 1982-1984
This was Shimano's first attempt at the "aero" market. It featured more rounded profiles, and oversized 1" pedal spindles/threads.
To use these cranks, you have two options: 1) use Dura Ace AX pedals, Deore AX pedals, or 600AX pedals, or 2) source the adapters to use 9/16" pedals on them.
Excellent used shape. There's light finish wear throughout. Tapers are near perfect. Blue paint inside engraved logos loks great
