as per post above. i'll look into the possibility that 7403 is hyperglide with modern 10mm attachment method, if so, i could use it. and would prefer it.
edit: looked into it... Velobase says, 7400 series durace hubs DO NOT use a 11mm hex bolt to attach the freehub. so i guess that's out.
Correct, except it's actually a 10mm bolt. But they might have made a 7400 7-speed Hyperglide Dura Ace hub.
I have a 7400 7-speed
Uniglide hub, but that probably wouldn't do you any good. I have the cassette to go with, but once you wear it out, pickings get slim. Especially for the last cog which is threaded to a smaller Dura-Ace-specific size.
