Dura Ace 9000 hubs
Moderator: robbosmans
These are finally available. Does anyone know if there is anything different on the new hubs besides color and the cassette body. I am tempted to build a set of wheels with the new hubs, but they would cost me a bit more $$$. Now I just want to justify the extra cash if there are no major changes from the 7900 hubs.
According to Shimano's site, the new hubs feature 11s compatibility and new seal construction.
Not really sure how much they changed with the seals but they look sick in black

Thanks for letting use know but you might as well round flange spacing measurements to nearest 0.5mm as 0.05mm change does not change spoke length in reality. Also easier to measure that way.

Guerdi,
How do I get from the numbers you posted to the center to flange distances for the 9000 cassette hub? If you know them I would appreciate it if you could post them.
Thanks,
Geoff
