Shimano 11-30 cassettes?

[jds108]

I heard somewhere that Shimano was going to start producing 10 speed cassettes in an 11-30 size. Yes, I know this means that I'm old and out of shape, but I'd like to try using this size.

Has anybody heard if these are definitely going to be made? What component level? And... When might they start becoming available?

I know that IRD makes one in this size, but after hearing more than one complaint that their cassettes are lesser quality, I don't want to try it.

Thanks - Jeff

I had an IRD 11-30 cassette that worked very well for me. I believe that Shimano has an 11-30 10-speed in the Tiagra level.

I had an IRD 11-30 cassette that worked very well for me. I believe that Shimano has an 11-30 10-speed in the Tiagra level, far less expensive than the IRD.

Even better, it's a 12-30.

Would a DA 7800 RD take a 11-30 Cassette? Even a Tiagra?

[that guy]

Ultegra, 105 and Tiagra now or very soon will have mid-length cage options that will take a 30 or 32-tooth cassette.

There is also a new Ultegra 12-30 cassette.

I've also been using a 9 speed Shimano mountain derailleur with Ultegra 6700 shifters and an 11-36 cassette and it works perfectly. A 10-speed mountain derailleur will not work.

I don't think running a wide range like that deems you "out-of-shape". All depends on the hills you are trying to crank up.

I have a SRAM 11-31 cassette that fits on a Shimano freehub. Maybe that would work?

Jeff I have the IRD cassette that I use when I head out to Woodside to do some climbing. I don't know who told you they were not made good ,the quality is equal to Ultegra IMO but that is a good deal for the Tiagra 12-30, may have to get one and stash it.

[dave thompson]

The short cage 6700 and 7900 rear derailleurs will handle an 11-32 cassette on *most* bikes. (*most* meaning depending on exactly how the derailleur hanger is configured. *Most* also means that I have personally run a 6700 short cage rear der and 11-32 cassette on a Time, Specialized, Milholland, Taylor and Serotta. I plan on have that combo on new bike next week.)

toosahn, oh, I'm definitely out 'o shape as I'm 15 yrs and 35 pounds over racing weight. But better than I was a couple of years ago...

skijoring - nice find, that looks like a heck of a good price. I did some searching and somebody from Israel put some Ultegra cassettes on ebay, but they don't have any for sale at the moment.

mistermo - do you mean 11-32? I have one of those, and it's just past the limit of what my DA triple RD will handle, and that's part of the reason I'm going to get a 30t max.

bobswire - IRD wants $180 for theirs, which always seemed steep to me (although I don't have the firsthand experience to know if the quality is worthy of this price), so I think I'll wait for the Ultegras to show up, particularly since the ebay price was $68, not including the $25 shipping fee

My bad. Yes, 11-32.

I here ya, I got mine on sale for $98,the most I've ever spent for cassette but well worth it when I need it. Good size for road bike that climbs.

[dd74]

Would a DA 7800 RD take a 11-30 Cassette? Even a Tiagra?
Yes. I had an IRD 11-30 back in my Shimano days. Worked great with the 7800 RD.

[vav]

Thanks!

[cnighbor1]

Suggest a compact crankset 50T / 34t while waiting for a 30T
Older Uniglide has a 32t maybe there is a 30t in one of thier series
Sora etc

[spartanKid]

I am currently running the Tiagra 12-30 cassette with a 6600 mid-cage RD on a Ridley frame and it fits fine. The B screw is only about halfway in as well. I bet I could squeeze a 32 on there no problem.

The Tiagra 12-30 cassette is available on amazon prime for like $35

[Sandy]

Shimano now lists on its website a 12-30 Ultegra 10 speed cassette:

12-13-14-15-17-19-21-24-27-30

I believe the largest cog the 6700 derailleur (like the 7900) is 28.

THIS. macho refusal to use wide range cassettes should have died with the 80s. I have a friend running the new tiagra 12-30 with an ultegra 6600 RD and he says it works great.

Tiagra is still 9s, pretty sure.

Take 2...see the 12-30 Tiagra 10s cogset.

The cassette I listed below is a 10 speed Ultegra, for sure, as it is on Shimano's website under the choices for cog configuration. I am having a new bike built and am using Dura-Ace 7900 primarily. The max size given on the Shimano website for Ultegra or Dura-Ace is 28 teeth. I bought a 28 tooth Dura-Ace cassette but would purchase the 12-30 Ultegra if I knew the Dura-Ace 7900 derailleur would work with it (or Ultegra) with my 50/34 compact. I have a larger cassette (11-34) Shimano XT and a 9 speed Shimano XT derailleur purchased for hilly rides. I thought Shimano might come out with a larger cog cassette. The Ultegra 12-30 is quite appealing to me.

Out of curiosity I threw on a IRD 12-30 cassette with DA 7800 derailleur, it is close to being at it's limit but seems to work fine.

Since the b limit screw sin't screwed all the way in, it's not really 'at it's limit'..yep, a 12-30 on a 7900 RD would probably be fine.

[Sandy]

I really appreciate the effort and comments. Very helpful. Thanks!


Sandy

[dave thompson]

Sandy, I'll go even further and say; because the geometry of the 6700 and 7900 rear derailleurs are extremely close, if not identical, and because of the success that I've had using 11-32 cassettes with 6700 derailleurs, the 7900 rear derailleur will *easily* handle a cassette with a 30t large cog.

[bobswire]

That's not the limit I'm talking about but you're right it was not needed in this instance for clearance.

You'd also be exceeding the RD's total capacity by one tooth, which isn't much but may be a problem in a few cases. It's interesting to note that Shimano media announced a new mid-range RD for bikes with 11-30 (and/or 11-32, not sure) cassettes for 2013. At some point total capacity is exceeded too far.

[sg8357]

Tiagra is still 9s, pretty sure.

Take 2...see the 12-30 Tiagra 10s cogset.

Note that it will not work with D/A 7800 hub.

[dave thompson]

It works with all Shimano standard 8/9/10 speed hubs.

[oldpotatoe]

Shimano now lists on its website a 12-30 Ultegra 10 speed cassette:

12-13-14-15-17-19-21-24-27-30

I believe the largest cog the 6700 derailleur (like the 7900) is 28.



Sandy

When they only made a 12-27, it was 27..when they started making a 11-28, viola, it was 28...bet the 12-30, with proper chain length, would be fine.

[oldpotatoe]

It works with all Shimano standard 8/9/10 speed hubs.

7800 hubs, some DA wheels and some Ultegra wheels were shimano 10s ONLY..I suspect, w/o actually seeing one, that the Tiagra is somehow not compatible with 7800 type, 10s freehubs. shimano made that mistake and corrected it quickly, good for them.

I was told by a representative from Shimano that in order to use the 12-30 6700 cassette, it must be used with the 6700 rear derailleur and not the 7900 that I purchased.He also said that although he was not sure when it would be available he guessed in about 4-5 weeks.
I told him that I had extra 7800 chains and wanted to know if I could use them with the 7900. He said I should use the 7901 chain.


Your comments above indicate how Shimano must have used magic for that to have happened... :):).

He is talking 'shimano'. No reason why the 7900 wouldn't work. If it works with a 6700 11-28, a 12-30 shouldn't be a problem.

10s chains are 10s chains..use the 7800, or Campagnolo, or KMC or Wipperman or sram...

[skiboycey]

I built an 11-30 ten speed cassette from two Ultegra cassettes - a 12-30 and an 11-23. I took the spider from the 12-30 (30,27,24) plus the 21 cog then the 18,16,14,13,12,11 from the 11-23 and put them together. In fact I used an 18 from an old 8-speed mountain bike cassette as I'd already used the 18 for something else from the 11-23 cassette. It works fine with Di-2 standard derailleur with only a slight drop in shifting smoothness from the 18 to 16, but I can live with it. No chain tension problems or other annoyances.

I miss the 15 tooth rear cog but missed the 11 more when using the 12-30 as I like to power down mountain cols. As I live in the Alpes and spend most of my time either going up, or going down, I can live with the loss of the 15 and bigger jumps on the cassette in order to get a super low 34/30 climbing combo for 13% gradient roads we have a lot of round here.

If someone tells you it won't work they're wrong - it's fine and has been entirely satisfactory for thousands of kilometres on my Fulcrum Zero wheels and Ultegra Di-2 equiped Scott CR-1.
