|I'm looking to upgrade to a Dura-Ace cassette. What are the specific cassette offerings from Shimano. What teeth are included with each? Any recommedations would be helpful. I live in the midwest. Wind and gentle rolling hills with an occasional steep climb. Thanks a ton!|

|Options are as follows:
Brackets indicate that the cogs are pinned together and cannot be seperated (they share a common carrier). I wouldn't overthink this if I was you; 12/23 is fine for 99% of people, if you deal with a lot of hills, maybe a 12/25; steep hills, go to the 12/27.

|The Shimano.com European web site has the details with exploded views and cog charts.
What I like to do is convert the 12-25 to a 13-25, adding a 16 in the middle. Too bad Shimano doesn't offer that in the D/A line, they have it in Ultegra, and you could use it.

|THANKS! This helps.|
|How do you do that?||the other Tim|

|Obviously, you need to do more than take out the 12 and add the 16/17. What specific combination do you end up with? I don't see how it could be done without using mostly ultegra parts.|

|I've used a 16 from an XTR cassette which seems to be the same material as Dura-Ace. But I usually order individual cogs from www.sheldonbrown.com. They are not Dura-Ace and not necessarily Shimano, but they are fully compatible. I think the 16 comes in real handy when drafting and matching someone elses speed. And I like to maintain a fairly constant cadence regardless of speed. Those mid-range cogs are more important to me than having a 12. I switch between 13-25, 13-26, and 13-27. You can make a "Dura-Ace" 13-26 by combining parts from the 12-25 D/A and the 12-34 XTR, with a 13 (not D/A) with built-in spacer from Sheldon Brown, but it's surely not cost effective.

|So the cheap way to do it would be to use non-DA 13 and 16 cogs from Harris. The
way would be to get the 16 from an XTR and the 13 from, oh, maybe Ultegra. Interesting. I switch between a 12-21 (w/16) and a 12-25, depending on the ride. Thanks.
