I have a 2 year old Dean with Dura Ace drivetrain. I have maxed out to the 27 tooth 9 speed
cassette. I ride a lot of hilly and mountainous rides. The cost of a Dura Ace triple upgrade is
very high, $639 in parts alone from Excel.
If you're into brifters you have to upgrade the left one. Beyond that, you need another crankset and
probably a bottom bracket, and a front derailleur capable of handling a triple. That could set you
back a bit, but you could do it for a whole lot less than $639 in parts if you don't insist on a
DuraAce triple. In fact, even with the extremely expensive DA triple crankset, it's kind of hard to
see where you could find a way to spend that much in parts.
Quoted message said:I was told that you could switch to an XT or XTR rear derailleur, get a 9 speed cassette with a
wider range (up to 32 or 34)and get most of the bang of a triple for a lot less bucks. Has anyone
tried this? If so, what can you report about your results?
You can. XT rear mechs are totally compatible with all road Shimano indexing shifters, and they can
handle a 34T rear. What's more, with the exception of cassettes with 11T small rear rings, you can
use any Shimano cassette on any Shimano hub. With a 39T inner chainring, a 34T rear will give you a
30" low gear, which is pretty much what most people with "road triples" have as a low.
Check it out for yourself. <http://www.sheldonbrown.com/gears/>
Of course, if a 30" low isn't sufficient, you really do need to go to a triple. But if you do, get
something other than the DA. It's way too much money, it locks you into Shimano chain rings, and as
triples go its choice of available ratios is suboptimal.
Compare what you can do with a DA triple with what you can do with a TA Zephyr. My long distance
bike's got a 24/36/48 front and one of Sheldon Brown's custom Century Special 13-30 cassettes. I go
down to about 30" on the middle ring, and down to about 21" on the granny.
