|I'm planning on doing some loaded touring and I want to lower the gearing on my bike... anyone know what the largest cassette size is that I can use with my Ultegra triple rear derailleur?|

|The cog size limit is the same as the rear derailleur for the double. The difference between the triple and double is the available chain-wrap (capacity). Shimano says the maximum cog size is 27. Many folks have reported going up to a 30 on the road derailleurs. I put a 14-28 9-speed on my wife's Ultegra triple without changing anything else. It works great. Suggest you check with www.sheldonbrown.com.

|Personally, when I want low gears I switch to a XT derailleur and a 11-32 XT cassette (there is even 11-34). This is not very expensive, you can buy derailleur for around 30$ and cassette for about 30$ as well.
|I agree with Pierre, use an XT||RickC5|

|Totally compatible with the rest of a Shimano 9-spd drivetrain, and not very costly if you buy online, like $35-40. Cost of an XT cassette is also relatively low, like $34. You'll need a new chain too.
My wife has an XT rear drlr and cassette on her Trek road bike. Gives her lower gears at minimal cost. She still uses the Dura-Ace double crank.

|Why the need for a new chain. I was pretty certain that 9 speed and 9 speed mountin were all the same.|
|The length of the chain is determined...||PeterRider|

|... by large chainring and large cog combination. If your chain is too short, you can damage your derailleur. I think the difference between a 12-27 cassette and a 11-32 is one (double) link.
And yes, this is the same chain, so you can just add links to your existing chain.

|I've done this with my 105 triple set up. I used an 11-28 cassette and it worked fine for touring.|
|27 according to Shimano, but 28 should work||LC|

|Never had any luck going bigger than 28 though.|

|it may take time to set up and you might need longer B-screw. No problems with 28|

|I use a bit longer B screw as one of the other posters mentioned. It makes a bit of noise in some of the granny ring combos, but work flawlessly. I've put 3000+ miles on it with no drivetrain issues. Several buddies of mine run the same combo and haven't had any issues.|
