Shimano's game-changer

In the cycling world, not much can happen with the addition of three grams. Try to imagine the best possible upgrade to your bike that falls within this weight. Give up? Well, we thought of something for all of you 7900 users -- the Shimano Dura-Ace CS-9000 11-Speed Cassette.

You read that right -- the weight difference between the 7900 10-speed and 9000 11-speed cassettes is only three grams. Needless to say, this was achieved through some clever engineering. To keep weight in check, Shimano constructed all of the sprockets over 16 teeth out of titanium. Additionally, the mid-spider carrier has been made from carbon fiber -- a rare occasion in the Shimano world. However, Shimano knows that the new Dura-Ace cassette is the heart of the 11-speed system, and its proudest feature is what Shimano calls 'Rider-tuning.'

What's this? It means that CS-9000 gear combinations were created to your standards. And we're not speaking in hyperbole when we say that the CS-9000 has been loaded with the best sprocket ranges that we've ever seen from Shimano. In fact, the cassette is even being offered in a massive 11-28t range for the go-anywhere-rider.

The Shimano Dura-Ace CS-9000 11-Speed Cassette is available in one color and in the sizes 11-23, 11-25, 11-28, 12-25, and 12-28t. Please note that the CS-9000 is only compatible with corresponding Dura-Ace 9000 components.

Just broke my second CS-9000 cassette.

  • Familiarity: I've put it through the wringer

And this happened mid-race in a cyclocross event... I'm sure this can be covered under warranty, but I don't actually *want* another Dura-Ace cassette. The SRAM 1190 is far better in construction and was the replacement for my first broken CS-9000. I also have another unit that's creaking under load. It'll likely break as well.

Great climbing solution for Juniors

  • Familiarity: I've put it through the wringer

For juniors making the leap to 11 speed, this is a great cassette. I was able to pair the 12-28 with a Zephr 44 front chainring, in order to meet junior gearing restriction rules, and with the 28 was able to provide good climbing gears for juniors who need the extra climbing help. My only wish is that they would make a 14-28 in Ultegra or Dura Ace, so we didn't have to go with an after market front ring. So far, we have put it to the test and it is running great!

Will the 11 speed Shimano Cs-9000 cassette...

Will the 11 speed Shimano Cs-9000 cassette work with SRAM Red 22 components? I would really like to have the 18t cog on the 11-23 cassette. SRAM doesn't offer an 11-23 cassette. I have an SRM power meter.

A number of people have been successful in running 11 spd cassettes with other manufacturer groupos. SRAM and Shimano will say optimal performance will be with matching parts, but they will work with each other.

I have Red22. I've witnessed the Dura Ace 9000 cassette shift BETTER than the Red 22 Cassette. I am going to keep my 11-26 for training and use a Dura Ace 9000 12-28 for my race which has lots of climbing.

Broken carbon spider

  • Familiarity: I've put it through the wringer

I've broken two of these cassettes. Neither had more than a couple hundred miles on them.

I had the same problem on an CS-9000 11-25 cassette earlier today. Has someone contacted Shimano for a replacement?

Responded on

I broke mine yesterday - its probably done less than 500-600 non-racing miles (all dry) and it happened simply pulling away from traffic lights. I am not heavy at 150lbs, been riding for 25 years and never even broken a single tooth on a cassette. This folded and snapped one of the Ti sprockets and broke the carbon spider. Not happy. Will definitely be requesting a replacement from Shimano - not good enough :(

Responded on

Shimano has an updated version with two rivets per arm instead of the single. It is a shame they haven't recalled these and instead just did a running change with the same part number. Make sure you report your case to the http://www.cpsc.gov/. I'd hate to see more people crash because they have the old version and it breaks.

Here is a picture of the old version and the new version: http://brimages.bikeboardmedia.netdna-cdn.com/wp-content/uploads/2014/06/shimano-dura-ace-da9000-cassette-running-change06.jpg

Can't ask for a better customer review! Excellent info. Thanks BOM

Responded on

Went out for a ride today and broke a second 9000 cassette spider I had on another wheel set. I agree with BOM, Shimano should have addressed the issue proactively, instead of waiting for customers to contact them after their cassettes break at the worst possible time. I would be sending both to Shimano to be replaced with the new design.

Have ridden Dura-Ace cassette's and chains with my SRAM group for years - smoothest, quietest combo there is. I currently have the SRAM 22, and you can use the SRAM Red 10-speed rear derailleur (change the pulleys - high/low) with this 11-speed cassette. Works totally awesome ! :) 186gm for 11/28

Responded on

I'm interested in the same setup. Can you explain "change the pulleys..."

Responded on

Greetings ! The change in the pulleys is due to the narrower 11-speed chain's'. But, doing the switch over from 10 to 11 speed; I would give it the old college try, and just use the same pulleys - therefore leaving you with only the need to adjust the high/low limit screws and whalah! If it shifts crappy, change them out - but I would try without next time :) So really, to change from SRAM 10 to 11 speed, just get the right hand shifter, front derailleur, chain and cassette - sweet! Hope this helps :)
