Still in its box and completely unused is this 1978 Shimano 600EX rear hub and 5 speed 14\24 cassette. It is obviously a Uniglide freewheel. Must be one of the earliest freewheel hubs? Complete with genuine skewer. 36 spoke and 120 OLN. Can't imagine I will ever use it! Sensible offers please. Will post pics early next week but it really is NOS and has never been touched.
