Bicycle Mechanics - Freehub tightness?
Bikeforums.net is a forum about nothing but bikes.

I recently replaced the old freehub on my Cane Creek Aerohead road wheels with a new Ultegra freehub (9-speed). But I can't seem to figure out how tight I should snug in the new freehub.
If I crank it down nice and tight, the freehub won't spin, but if I back it off some, the freehub wobbles on the hub. And then when I reinstall the cassette and put it on the bike, it "ghost pedals" on me.

Are you sure a Shimano freehub is compatible with the Cane Creek wheels? Do they use a Shimano freehub?
BTW, almost all Shimano hubs I've seen have a thin spacer behind the freehub body. Any chance your hub is missing this spacer?
I checked the cane Creek site, and yes, my wheels do use a Shimano-compatible freehub. But no, there wasn't a space on the old freehub and the new freehub didn't come with one, either.
When in doubt, see Park's site: http://www.parktool.com/repair/readhowto.asp?id=88
It gives a range of torque values for the freehub, but the average is around 30 ft-lb.
But something is wrong if the freehub binds when the mounting bolt is tightened. Best check with the hub manufacturer.
I called Cane Creek and -- go figure -- all their wheels (mountain and road) are built around an LX/XT freehub. Apparently, the spacing of the press-fit with the hub is slightly different from Ultegra/Dura Ace.
I guess you do learn something new every day. I've ordered an XT M-750 freehub from my LBS, and I might get to install it and sneak in another ride before everything goes white up here.
But I get to keep my wheels, which is awesome, 'cause they're great.
