Dura Ace triple

I'm a bit confused by the Dura Ace triple options.
Can I use a Dura Ace triple FD with standard 52-42-30 rings or must I
have the 52-39-30 Dura Ace rings?
Do the Dura Ace triple shifters work on any triple ring setup?

I am sure Sheldon will respond here. It seems the answer is that you must
use the supplied rings as the inner is directly attached to the middle and
standard (74mm PCD) inners can not be used, and standard (130mm PCD) middles
can not be used.

Ultegra is different though.

The Dura Ace tripe FD is optimized for a 14 tooth gap between big and middle
rings, whereas Ultegra is optimized for a 10 tooth difference.

As for the shifter compatibility, I defer to the DA experts (I wouldn't
touch the stuff myself).

I've used the D/A triple shifters and rear der with my otherwise Ultegra
triple set-up on two bikes for a year now. I really like the smoothness and
ease with which the D/A shifters.work, and they perform perfectly. I'm about
to do the same thing on my wife's Calfee.

But no DA FD, right?

I've not tried the D/A triple front der yet, though I do have one to install
on one of my bikes this winter. I don't see any reason it wouldn't work OK.
It's got more lift to, as the other poster said, shift from the 39 to the 53
rings.

This is true. If you use a DA triple crank, you are limited to
52-39-30, period. Unlike the ultegra or other triple cranks that use
a "standard" 110/74 bolt pattern, Shimano decided to "triplize" the DA
triple crank and does what's stated above attached the small inner
chainring to the middle chainring. Both are proprietary to Shimano and
NO OTHER CHAINRING IS AVAILABLE. IF you want to use DA triple, get the
ultegra triple crank with everything else DA triple and be done. If
you're one of those who feels that the ultegra triple is not "fancy or
good enough", take a look at TA cranks he

The DA triple front derailleur will rub on the 42 with a 52t big ring.
If your big ring is 53t and you get the front derailleur about 3 mm
above the chainring, it can work.

Hi, I'm using a DA FD with a Tiagra 52-42-30 crankset. It works fine,
but seems to need careful setup. When I had it installed, it worked
fine, but after I took the bike in for the free 90 day tuneup, it was
rubbing. I took it back and they were able to adjust it correctly. I
didn't know that I'd have been better of with an Ultegra FD, when I
requested it as an upgrade to the Tiagra FD. It will all workout
though, as I am most likely going to put a DA triple crank on the
bike. I have read the reasons not to go with the DA triple, but I
don't think that for the type of riding I do, I'll want to change the
chainrings. I want the 53t and on my other bike I have a 52-39 double
and I like the 39t.

I'm running a 25-14 cassette on the bike now. I was going to go to a
23-13, but I got to thinking. I have a 25-12, so I may try taking the
25-14 and remove the 23, then add a 12 on the end. I'd prefer a 13,
but I don't have one. That would give me 25,21,19,18,17,16,15,14,12.
With the 53-39-30 crankset, I think that will work well for me.
Does anyone see a problem with the 25 to 21 jump or the 14 to 12? It
is only on the rare downhill, that I need to go lower than the 14, so
the 12 would work there. My other bike has a 6-speed freewheel, so I'm
used to the big jumps having 28,24,21,18,16,14. I do like the tighter
ratios, where I have them. That is why I went to the 25-14, so I'd
have an 18 and a 16.
Life is Good!

Must use a DA triple front der with a DA crank. Can use a DA triple front der
with an ultegra crank. Cannot use an ultegra front der with a DA crank.

DA triple is very finnicky and for best possible results, use DA triple stuff
in the front.
