dura ace 10 spd hub width(4 posts)

dura ace 10 spd hub widthdave11

If I go to DA 10 speed on my new bike this year, am I still going to be able to use my four sets of wheels made for DA 9-spd.

In other words, is the rear hub width increasing or are they cramming more gears in the same width by decreasing chain width and gear spacing?

If it's different, I guess I'm going to have to stick with 9 speed for now due to my significant wheelset investment.

Thanks!

The cassettes are backward compatible too (i.e., new 10-speed fits on old 9-speed wheel),

New Shimano 10spd hubs will have deeper splines on a lighter alloy freehub body like Campagnolo has but they will be spaced the same as current 9spd Shimano offerings. This means a 10spd cassette will fit on a 9spd hub but the new 10spd hubs won't accept a 9spd cassette as the splines are too tall for the old cassette.
