|Can I get one now? How much will it cost? How many parts will I need to change?|

|Yes, you can get one now. Excelsports.com sells them for $269.95. I don't anything about the parts though.

|It's actually really expensive. If you have Dura Ace 9spd now, you'll have to change a ton of parts. You need:
- new shift levers. Both, because they don't sell only one. You may be able to buy a left lever used, but most of the people selling just a left lever have taken it off because they're going to downtube on that side to save weight, and most gram heads aren't riding triples. You moght be able to find someone who lost the right lever in a crash, but very few people will sell something used that's been on the market for a month. So you're looking for $275 for levers.
- Then, you'll need a new crank. This will run you another $275.
- a new BB. you have to have room for that extra ring. $50
- front derailleur. It has more travel. The standard double ring front derailleur doesn't move enough, even with setting the limiter screws. $50
- a new rear derailleur. This will take more chain cross, which you'll have with the extra ring. $85
Your grand total: $735 If it's worth it to you, great, but it's a ton to pay for an extra ring. Do you really need it? Double is really plenty for most roads. Unless you live in Colorado, or something. Have you tried getting a wider spaced cassette? You can get a 12-27 in Ultegra, which is just about as good as DA, in a cassette anyway. If that's not enough, you can get an XTR cassette, which is 12-34, and it will work great with a Dura Ace drivetrain. All you'll need is an XTR rear derailleur to go with it. Going to Deore XT will save cash, as the cassette isn't made of Ti. It will be only $100. But if you go with XTR, that's a $200 upgrade, still not $700. Of course then you may not have your favorite cog.

|cass would be the way to go.
if you need mtb cass go with XT (it comes in 11-32 11-34 and 12-34). I've seen XTR Ti cogs bent by strong riders, pls Ti cogs don't last. Shimano clams 60g diff in weight, it's bogus, XT is only 1oz more.
the other option would be to sell your bike and get knew might end up less then retrofitting DA triples good luck

|Well, also remember that he can sell has used DA double stuff (sounds like a cookie) for decent money, so that takes the sting out of the new. |
Also - you can now get the 12-27 cogset in DA, not just Ultegra. You can also replace the 39 with a 38 for tiny improvment in lower ratios.

|you work in shop and get a good deal on DA otherwise you pay retail and it may end up cheaper to get new bike
yeah his DA sounds like a cookie he'd be selling complete grupo (minus hubs and cass he-he)

|For what it's worth, I put an XTR 11-34 cassette and rear derailleur on my "climbing bike," combined with a Dura Ace crankset with 52/38 rings.(Also used downtube shifter for the front). It worked like a charm on the big hills, allowing me to spin up the steepest sections even when bonked and dehydrated. It shifted well, but the spacing is a bit large. I think the total range is about the same as the triple, just fewer duplications and intermediate gears.
I worked it out and this was lighter than the triple setup, and much, much cheaper. That huge 34 cog sort of looks goofy in the rear, though. But then, I can change it to anything else (11-21, 12-27...), keeping the XTR derailleur on, in about 2 minutes.

|it's equivalent of 12-27 on triples
I like your idea why climbing bike? just get extra rear wheel :)
