Dura Ace 9000 cassette

Focus-rider

Folks, anyone here had any issues with the dura ace 9000 cassette? Im just about to buy one but hearing alot of people say they are having problems with the cassette carbon spindle breaking quickly. can anyone tell me what the differences are between this and the ultegra cassette? is there any compatibility issues running a full dura ace 9000 groupset and a ultegra cassette? especially regarding the chain. if anyone has one are you noticing any creaking under load in certain gears ie the ones that are attached to the carbon spindle.
Also, im thinking of going for 11-28, do you notice a huge gap between gears or should i opt for the 12-28. I do alot of climbing and presently have a 11-25 but was thinking of the 11-28 for some bigger climbs i have planned.
Mainly want to know the differences between the ultegra and dura and compatibility issues.

No experience of 11 speed but would have thought an 11 speed Ultegra cassette is as compatible with 11 speed DA as 10 speed Ultegra cassette is with 10 speed DA.

What cassette was originally on the bike with the DA9000 group set? Or are you putting it all on an older bike?

Hmm - you save 50gr over Ultegra (11-23) but it costs you £83 extra. For a consumable.

I'd go Ultegra and then you dont need to worry.

I've used the 9000 cassette for over a year with no problems at all - however there's a long thread on weight weenies for those that have. I have the 11-28 and really don't find the gap an issue; it's useful to have the bail out gear for big climbs.

You can use an Ultegra cassette without issue, or you can use a SRAM cassette. Quite a few people go for the top SRAM cassette IIRC.

I have the 9000, the 6800 and the SRAM cassettes, all work with either 9000 or 6800 Shimano 11 speed. The problem is the use of a carbon fixing attaching the largest 3 sprockets for the 9000 - something they haven't used for the 6800. This carbon fixing has been breaking, more often that it should. I have one 9000 cassette that sounds a bit gnarly in the larger sprockets and a couple that are fine.

As the cassettes wear out I am moving over to the SRAM XG1190 which is a fantastic piece of kit. More expensive, but seemingly more reliable.

Is the creaking issue a known problem?
I have a 12-28 DA9000 cassette and I get a creak on steeper climbs when in the 23/25/28 sprockets and 34 chainring....although the bike is resting for winter while i use an older bike so havent ridden it since Sept/October.

PS 12-28 is perfect for me, i just think of it as a 10 speed 12-25 (same ratios) with the bonus 28 there as a get out clause!

I got the 11 speed Ultegra hooked up to my Wahoo Kickr and have had no issues - 80 hours since October.

For the road I've been using the Dura Ace 11 speed cassette. I've put into >170 hours since may with the original cassette.

As I've got DuraAce shifters and derealiuers I'd never consider having an Ultegra cassette for the road.

Reading the Weightweenies thread i think i might change mine to a SRAM PG 1170 in 11-28 guise, still retains the 16 sprocket were as the 6800 doesnt.

So if I decide to go with the SRAM xg1190, do you need to run a SRAM chain for best results or do you run the dura ace 9000 chain to match the chainring?

Your DA chain will be fine. Use it until it wears out, then get a KMC one

Focus-rider

I ain't bought the chain or cassette yet, just have all the rest of the group set ready for the new build, so I'm quite flexible on what to get

mamba80

Ultegra and replace with the DA 11sp when they introduce the 9001 version

In which case, I would get a KMC chain.

Focus-rider

So just to make sure I have this correct. Rather than buy the dura ace 11 speed cassette I can install a seam xg1190 cassette? If I'm using this with a full dura ace 9000 group will there be any issues or degrade in performance? Do I need to use the SRAM chain or will dura ace or kmc chain work better? Do I need additional spacers on a shimano free hub ? What problems might I encounter mixing SRAM and shimano?

If its an 11 speed SRAM cassette it fits on the hub with no spacers, just like a 9000 cassette.

I have an 11 speed SRAM cassette and have bikes with KMC 11speed chains and 9000 chains. Both work.

I am not sure if Shimano or SRAM would suggest mixing for optimal performance, but in the real world it works just fine.

SRAM and shimano cassettes, chains and chainrings are inter-compatible.

KMC chains also git SRAM and shimano setups.

I (and lots of other people) prefer KMC and SRAM chains over shimano because they have quick links for easy installation and removal. I prefer KMC chains because I find that they last longer and are generally better, but that is anecdotal, of course.

The DA 9000 cassette issue is real and it is frankly pathetic. Don't buy it

Focus-rider

Perfect folks thanks for that. Will definitely go with the SRAM cassette, not decided on chain yet but that's not an issue. The dura ace cassette issue just worries me a bit so will definitely not go that route

From what I've read on WeightWeenies it seems to be a common problem and may be a precursor to the carbon block failing. The problem seems to boil down to too loose and you get movement which destroys the carbon cradle, too tight and you crack the carbon cradle...

Unfortunately this looks to have been one of those design errors that made it into production (like the Shimano quick link which while very elegant and simple to use tended fail after 1-2,000 miles).

Focus-rider

Thanks for all the advice guys, new 11/28 sram XG1190 cassette bought along with the dura ace chain. Now just wheels and seat post then the bike is built. Not long to go.

I have gone through 4 DA 9000 cassettes each time the carbon/plastic inner bracket cracks on cogs 3+4

will call shimano as well as the shop this time to see if they have a solution.

the cassettes breaks while under load in a gear (not changing). i am a bit on the heavy side 95kg so probably a bit of force but im hardly a pro rider so shouldn't be a problem

Yes, it's called Ultegra...

I have 2 da9000 cassettes and they both creak, and I'm hardly a power house. I just bought a SRAM xg1190 and its so silent (da9000 chain), its sublime. Only gripe is I wish they did a 12-28.

Mccaria

Have pretty much moved over to 1190 for lighter wheels and 6800 for training wheels. Reading the WW thread it seems like they have changed the design on the 9000 cassette, presumably to beef up the carbon. Too late for me.

9000 is a good groupset and the gear shifting is fantastic. However have been disappointed with Shimano on this one, clearly there has been a problem with the cassettes and they have also redesigned the Sti levers with the launch of the 9001 changing the exit angle on the gear cables. So I am left with cassettes I don't trust and "old style" 9000 levers. Lesson learned, will be more circumspect next time Shimano launch a new design.

I always wondered who buys Dura Ace (or Super Record) cassettes... big bucks on something that in the best case scenario lasts 3000 miles

Where did you get that figure from?

ugo.santalucia

Is it not the kind of average you get out of a cassette? You can run it to death, but then what's the point of getting an expensive one. IME top of the range consumables or bottom last exactly the same... it's better to have a new Tiagra than an old Ultegra.
I had Alivio 9 speed chains that lasted longer than Dura Ace 9 speed actually....

No.
Especially as I tend to only use the DA during good weather.

and because Shimano chains snap

I thought KMC make the Shimano chains.
