SruaAce 9spd - 10 spd conversion question

[Jeff]

I have Dura-Ace 9 speed on my bike now and would like to convert to D-A
10 speed. What parts do I need to make the conversion? Do I really
need a new crank or front der?
thanks in advance

 

[David B.]

Somebody correct me if I'm wrong, but I think you only need a cassette,
shifters, and chain, and _maybe_ new pulleys for the rear der?
Definitely no need for new crank or front der.

The steel DA freehub used through 2003 will accept both the DA and
Ultegra 10s cassettes. You will also need a shifter that will step to
match. The only 9/10 incompatibility issue with DA is that in 2004,
the DA freehub was redesigned and made out of aluminum, and they made
the splines taller to get around the problem of the cassette chewing
into the aluminum. The DA10 cassette will fit on the steel 8/9 bodies
just fine, but the older 7/8/9 cassettes (and presumably the Ultegra
10, though I haven't checked) will not fit on the 2004 DA10 body.

Can anyone confirm this about the Ultegra 10 cassette not fitting on DA 10
freehub.
I just ordered the cassette from my LBS but I didn't deal with a techie.

All you need is right lever, cogset and chain...nothing more regardless of what
some twits say on a website.

Where ohh where does this idea that pulleys are needed. There is one website
that spews this, a MO place(BB) but NOT necessary to do anything with pulleys,
They are just guides for the chain afterall.

Yes it does, the ultegra and DA 10s cogsets are identical except for all steel
instead of steel/ti on DA. Altho shimano does some wierd stuff, I don't think
they would make a ultegra cogset in 10s that wouldn't fit onto a DA 10s hub.

Noted and filed; thank you. (Yes, Shimano does some truly wierd
stuff, and sometimes it's also not so smart. Looks like they decided
to just use the same die layout for both the DA and Ultegra stampings;
a good decision IMO.) (But I'm not so sure that any down-market 10s
cassettes will share the feature when they finally appear; time will
tell, and I might be pleasantly syurprised.)
