Thanks! And thanks to Roger G, for looking this up as well.
Quoted message said:All _7-speed_ RSX STIs were "double/triple" This is the model SL-A410 7-speed RSX groups used a 46
tooth large chainring.
That's actually double-good -- I can get the gearing I need either way -- with a triple, or the 110
double. I would have settled for the dual mode shifter!
After playing with your neato gear calculator, I discovered a 34-48 double and a 12-28 7sp cassette
gives almost the same range as most triples, plus, it works out to an almost-perfect half-step
system. I like this...
Quoted message said:7-speed RSX was made from the 1995 through the 1998 model years.
So they're all probably 130mm dropout spacing -- nice strong wheels with a 7sp hub...
Quoted message said:For the 1999 model year, RSX was completely revamped, became 8-speed and used full sized (52
tooth) chainrings.
Quoted message said:The 8-speed version was listed with both a double (SL-A416) and a triple (SL-A417) STI unit.
So *those* lefts are probably *not* double/triple compatible...
Quoted message said:8-speed RSX was only made for the 1999 model year, and didn't sell well, so the parts are much
less common than the 7-speed version. I don't recall ever seeing a bike with an RSX 2 x 8 system.
Quoted message said:RSX was replaced by SORA in 2000.

Yeah, but used RSX bikes are cheap! And the 7sp versions are apparently very versatile... I think
I'll buy one.
You know, I want to like Sora -- I bet it actually "works" better than, say, 8 year old Dura-Ace.
The newer STIs, even the cheap ones, all have the same crisp, light action. And the brifters are
much more elegant than they used to be. Some of the older STI units were pretty clunky.
Sora's one lever, one button design is very sleek and elegant. However, I hate how you can't reach
the release button from the drops, unless you have thumbs like Uma Thurman in that Tom Robbins
movie. This really sticks in my craw. First, because it would have been so easy to just make it
right. Second, the cynic in me says it's a carefully contrived ploy to sell people *another* bike,
after they've been riding awhile, and using the drops more. Other than that, Sora is really good
stuff. It seems to have brought the price of a "real road bike" down a notch or so -- Sora-ly
needed, IMO.
