Short answer is... yes. Also, I believe the 9 speed cassette will in fact use no spacer.
A quick web search brought me here:
http://sheldonbrown.com/k7.html#hyperglide
With this info under the Hyperglide section:
" Also, hubs marked "8-speed", "9-speed" or "10-speed" will work with any number of sprockets! (Add a 4.5 mm spacer before installing a 7-speed cassette on an 8-, 9-, or 10-speed hub., and the included 1-mm spacer before installing a 10-speed cassettes on an 8- or 9- speed hub.)"
The Harris Cyclery site is a wealth of info, particularly for this and much more obscure compatibility info. If you are ever in Boston with some free time, go there.

I just purchased some mavic elite rims and plan to move my old pg1070 from my old mavic askium to the new rims. I want to use my old askiums for my rollers. Would it be possible to put a pg950 on them, or will I need a different spacer ring? Thanks. Mike in Greenville
