Just seen the Shimano announcements and the specific mention of a new 11-32 cassette was really interesting as I have many hours in the mountains this summer...

Will the 11-32 cassette also work with the new Dura Ace rear derailleur? Or is it Ultegra only?

Thanks all, FJ

What I just read on Velonews said that DA-9000 users would need to buy the new Ultegra 6800 RD.

Ultegra 6800 is will have a medium length cage RD available for the 32-tooth cassette, so unless DA makes the same, you're S.O.L.

I've seen plenty of mountain bikers use a 10t upper pulley to run road derailleurs with 11-32 cassettes.

I've run a 10spd 12-30 Ultegra cassette on a standard 6700/7900 rear mech okay (on three separate bikes now) if that's any good to you?

My brother has used a short cage Shimano 600 rear derailleur with a 32 tooth rear cassette. So despite what Shimano says, I think the short cage Dura Ace rear derailleur will shift the 32 tooth Ultegra cassette just fine.

It depends on the rear hanger. Shimano says 28t for 9000 so that it will work. Exceptions are there, but I wouldn't spend that much money on the experiment.

Shimano and Campagnolo missed the boat on this. Sram has large capacity rear mechs at the Red level.

you can order the inner/outer RD cage plate for the 6800 and fit it to a 9000 RD

That depends on the mounting for the cage plates. You can do that ONLY if they are identical. That remains to be seen.

Might be old news by now, but to the OP the new Scott Solace 10 has a complete Shimano Dura-Ace 9000 11-speed groupset, with a 50/34 crankset and 11-32 cassette combination.

I have the 11-32 cassette and GS mid cage RD, they work great, the cassette looks big, it is too much for the SS short cage RD to handle.

I was researching this for ages too.
I'm building a new bike on a well priced Dogma 2 frame.
I wanted a Dura Ace 9000 but also an easier gear since I live in a area with mountains and some shocking sharp punchy climbs.
So my bike shop are putting a 11-32 ultegra cassette on the Dura Ace, and they say it will work.
I'm a total tech newbie, so I hope they are correct.

Running stock DA-7900 with 12-30 just fine. If you get a bit creative with the chain length, B screw, and possible 10t top pulley, 11-32 should be doable on most (all?) frames (RD hangers), I would reckon. For chain tension it might be advisable to trim to big-big cogs without the extra 2 links, at the price of giving up the front-big / rear-big cross-chained gear (which one shouldn't use anyway).

BTW, long cage Ultegra 6700 handles 11-34 out of the box (on another frame of mine). So there's room to go to an even wider range with that RD (probably not too much demand, though).
