q about DA 9spd STIs

[Dan Baker]

A couple places are advertising Dura-ace 9 spd STI shifters
for sale, and I am thinking about replacing an aging old 105
8 spd system on my road bike... Nashbar says their DA STIs
are not "flight-deck" compatible, whereas Performance says
theirs are. But they are both listed as model 7700 .?!

My question is: does this mean they are different years? is
one functionally better than the other?

I doubt I would install flight deck on my single bike. i do
have it on my tandem for visual feedback on the current
gear, but I dunno if I'd want to messaround with setting it
up on another bike, so the flight deck-ness of the shifters
is irrelevant. I am just concerned about differences in
functionality if they are different years or slightly
different internal design.

comments?

Note that the 7700 version only works with double
chainwheels, won't handle a triple. That's probably why
they're being closed out. The current 9-speed 7703 does work
with double or triple cranks.

ST-7700-C is double compatible with Flight Deck.
ST-7700 is double without Flight Deck compatibility. It may come with the the "Gear View" that can be inserted into the right shift cable. There is no functional advantage of one over the other.
ST-7703 is triple/double and Fight Deck compatible.
All 3 DURA ACE units have 3 year warranty.
ULtegra works well and is usually priced quite a bit lower, and is double/triple compatible. Ultegra is warranteed 2 years.

I bought the non flight deck version a few years ago and
have had no trouble. I think Peter Chisholm says the non
flight deck are actually more reliable (and he sees a lot of
them). The price I see at Nashbar doesn't look that great. I
paid $199 for mine. If I had it to do over, I'd get Ultegra
or 105. I've actually got 105 on my other bike and I don't
see any real difference. And as Sheldon points out, Ultegra
or 105 work for either a double or triple.

Nashbar still carries the original non-flite deck 7700
shifers, which they designate "7700-L". Most everybody else
sells the newer 7700-C flite deck model. The non-flite deck
model, lacking the internal wiring harness and additional
parts, is a few grams lighter. They are slightly easier to
set-up and are said to be more reliable than the flite deck
version. You know, "fewer things to break..." Nashbar just
had a 20% off promotion, but it ended yesterday.

Flitedeck 7700 came out in 1999, I think. Were the same thru
2003. My experience is that the non-flitedeck were more
reliable but still we saw a lot fail. Why not upgrade to
Campagnolo ERGO/rear der for 9s or even 10s? Never have a
failed lever problem again.

thanks for the input fellas... The older shifters would be
fine for me as I plan to keep a double on my roadbike.

After pricing and looking up weights on shifters, cassette,
derailleur, crank, bottom bracket it looks like DA is about
$350 more than ultegra for an 8oz. total difference. Its
looking like Ultegra will be just fine.

I know that I don't HAVE to replace whole crank for the 8 to
9 speed conversion, but my BB and chainrings are pretty much
shot, so I might as well.

thanks again, d

I know that for me, the difference in the feel of the
STI between D/A and Ultegra makes it worth it. D/A just
feels better.

Granted, I bought both my pair semi-used, so paid a little
less for D/A than I would've for Ultegra.

I use DA STI on one bike and 105 on the other. Both were
bought new. I can't say that the DA shifts any better. Yes,
it's got metal in places where Ultegra/105 use plasic, but I
don't think that's very critical. Cables/housings may
account for a different feel.

Also, Shimano may not be supporting 9sp DA now that
10sp is out.

I've noticed firmer clicks in the D/A. More "Campy-ish" vs.
Rapidfire Plus.

I'm guessing that Shimano's going to phase out their 9sp
stuff in a few years, but there's probably going to parts
availability for the foreseeable future. Heck! You can still
get 8sp D/A. (and 7, and 6...)
