I am trying to figure out if Shimano 600 8 speed hubs are compatible with 10 speed cassettes SRAM etc (not the new Dura-Ace)


Here's the link (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=160222418276&ssPageName=STRK:MEWA:IT&ih=006) ---

Seller has not responded yet and would be nice to get this for my build unless someone here get's it before me

Thanks

The NON DuraAce 10spd cassettes are back compatible with 8spd/9spd hubs.
SRAM 10spd cassettes are compatible with 8-9spd hubs. Some discussion
of this in Sheldon's site for further qualifiers that don't apply. Look under
cassette.

I have a Shimano 600 8 speed hub and I have used both a Shimano Ultegra 10 speed and a SRAM Rival 10 speed cassette on it with no problems.

The 600 8-speed hub can take 8-, 9-, and 10-speed cassettes. However, the freehub may not be "compact" or may even have external threading for Uniglide compatibility (mine does), both which require some adjustments when using a cassette that starts with an 11T.

I believe 10-speed Dura Ace cassettes are compatible with any 8/9/10-speed Shimano hub. It's the Dura Ace 10-speed hubs that won't accept 8 or 9-speed cassettes.

If it helps determine anything, my SRAM cassette has an 11 and I didn't need to do anything special. Mine is also threaded on the outside.

Interesting. I once put an 11-30 8-speed cassette on my hub and it wouldn't snug down w/o a spacer behind it all.

That's my understanding too.

I actually had the same problem with an 11-28 8 speed cassette on the exact hub mentioned in my previous posts. Swapping the 11 with a 12 solved the problem. Why the 8 speed cassette was a problem and the 10 speed was not, I'm not quite sure.

Some 7 and early 8-speed freehub bodies had splines that ran all the way to the very end of the body and would not accept an 11T cog. Newer bodies were labeled "Hyperglide-C" (the "C" was for compact) and had the splines shortened about 1mm and would take an 11T cog. A few minutes with a Dremel could convert the early bodies to the C-configuration if you wish.

Sheldon Brown's web site has a pretty thorough explanation of this.

Thanks for all your responses. Seller responded and he said he has used 9 and 8 speed cassettes. I am still not quite sure whether s it will take an 11T ( I have SRAM BTW), I asked him again. I don't mind dremelling the cassette body or maybe just finding a compact freehub -- question is will any compact free-hub attach to the 600 hub? The Bike Coop in Albuuerque usually has a freehubs in their parts bin

I am not really into rebuilding this wheel. Just want to use it ASAP.

The way I see it, it's like a nicely built shimano-hubbed wheel with an aero fairing

But why did the 11t cog not work on the 8 speed cassette but it did work on the 10 speed cassette? I'm pretty sure mine is the Hyperdrive version, but would have to look again to be sure.

8-speed 11T cogs don't have the spline cuts all the way through them so the splines on the freehub body have to be short enough to provide the needed clearance. All 8-speed freehubs bodies were "Hyperglide" but not all were "Hyperglide-C" Perhaps by the time Shimano designed 10-speed cassettes they were able to change the 11T cog configuration.

The Dura-Ace 8-speed HG freehub wont fit (may not even be compact, anyway). Any 9-speed freehub will fit. I'm not sure about 10-speed freehubs.

I think that since the 9- and 10-speed cassettes are just a bit wider than an 8-speed to begin with, they don't need the extra 1mm spacer to snug them down on non-compact freehubs.
