I swear, when someone shows up at my club with a new bike, the first
and only topic of discussion is weight.
WEIGHT IS NOT THE ONLY CRITERION WHEN PICKING BIKE FRAMES AND BIKE PARTS.
Thank you. I'll lower my voice now. I was very good today on my clubs
bike ride, 29 miles, 3900 feet of elevation, lots of sections in the
high teens in grade. I kept my mouth shut, mostly, did not swear, and
did not mention that I thought my companions' bikes were ridiculously
overgeared for what they were trying to do with them. I did not say...
...No, a compact double is not significantly lighter than a triple,
and if you can't climb that hill without weaving back and forth and
getting in my way, not to mention dangerously cutting across the
center line, you should put a triple on your bike.
...You can't notice a two pound difference in weight. You can't,
unless you can tell me with a straight face that you climb
significantly faster when your water bottles are empty.
...If you weigh 98 pounds, stiffness and compliance in a bike are
irrelevant for you. Also, if you weigh 98 pounds, you're not climbing
faster than me (when you do) because your *bike* is lighter than my
*bike*. I could ride a weightless bike, and I'd still weigh more than
you and your bike put together.
Yawn. As I said, I love riding with my club. But jeez, there's more to
bikes than how much they weigh.

Any Rivendell type is probably by nature a nonconformist, who will show up to a fast club ride with 40 mm tires just to experience the incredulity of the other club members. Some of us will get miffed if the other club people don't appreciate that the Riv is anything but heavy and primitive. (of course, the Riv group has its own nuanced gospel of conformity)
Side-story about weight: we mostly carry touring type bikes at my shop. Nothing lightweight by racing bike standards. Amazingly, it's a frequent occurrence for a customer to lift a 28-lb bike and say, "wow, that's light!"
That's ridiculous. The best guess for a crank for a 70-year-old woman
riding in an area with hills is a triple, with very low gears. Isn't
it usually possible to install a triple on these bikes with stupid
compact doubles? I would have suggested that the woman get her bike
changed over. If one is in one's 70s, one shouldn't be missing out on
good riding-- when we start getting on in years, we need to take
advantage of all the riding we can squeeze in.
One of the people I was ranting about is the 98-pound woman, who is in
her 60s and a strong climber. She has a compact double on her bike,
and she assured me that a triple would be too heavy. And yet-- I was
stronger up some of the *very steep!!!* hills, she was stronger on one
long *steep* hill, though she ended up zigzagging. But then, at the
end, there was one more steep hill. And, having not had to kill myself
in a too-high gear on all the other hills, I rode up it and she
skipped it. People should ride the bikes they want, but it seems to me
that some of these riders have chosen bikes that are keeping them from
doing riding that they would enjoy on a different bike.
And the other thing about these light bikes that annoys me is, OK, you
will ride faster up hills on a lighter bike, all other things being
equal. That is perfectly true, and in my club we do a lot of hills.
But... this is only a positional good. That is, if everybody buys a
lighter bike, then everybody will be just that little bit faster, but
nobody is any better off. That is, Ted can still beat Susan, and Susan
can still beat Alan, but the order of arrival at the top of the hill
will be exactly the same as if they all rode Rivendells. It's a
pointless arms race. And my club is big, so we have lots of rides for
people of all abilities, so riders can always find people of about the
same speed anyway.
A Riv, on the other hand, has intrinsic value that doesn't depend on
what other people are riding. No matter what my riding friends are
riding, my Roadeo will still be beautiful. It'll be comfortable, and
it will handle like a dream. Unlike those carbon fiber bikes, my
Roadeo fits fenders so I will still be able to ride through winter
storms while they're staying home. My green Atlantis will still go
anywhere anytime carrying pretty much anything I want, and my purple
Atlantis will be the perfect touring machine that I can ride every
day, loaded, for weeks and months, through mountains and forests. I
get pleasure out of my bikes, independent of what other people have.
Thank you, thank you, thank you! Nearly everyday, a coworker, who rides a carbon fiber bike, comes in my office, lifts up my Atlantis by the top tube and exclaims: "My god that's heavy". I've run out of things to say to him in reply so I may forward your post instead.

Sadly, most cyclists don't actually know much about bikes. So picking up a bike and checking its weight is a bit like looking at a used car and (literally) kicking its tires. And the bike industry uses weight to sell bikes the same way that the car industry uses horsepower...it's a number that can be thrown around despite having almost nothing to do with utility or enjoyment. It's dismaying to eavesdrop on buyers at a bike shop or listen to guys on a sales floor talk about the Trekdaleized bikes on offer.
Of course, at the other end of the spectrum, where folks maybe know too much, are the bike collectors with never-ridden wall-hangers who want to talk about thinned lugs and tubing diameters and patina. Gee, those Delta brakes don't work very well, but they sure are pretty!
I'm just glad I have room in my garage for several bikes. I have a CF weight-weenie bike that is fast and fun on group rides, I have a steel bike with fenders and lights and bags, I have a full-squish mountain bike for trails, I have a rigid MB for other days. I even have a snowbike for winter trail riding. Different tools for different days.
I try to keep a sense of humor about the weirdness of cycling clans, but sometimes it's hard.

They almost certainly also told her a compact double gave her the
identical low gear that she would have with a triple. And, for a very
narrow set of assumptions, it does.
Of course, that set of assumptions doesn't include cassettes with 32, 34
or 36 tooth sprockets, or granny rings with 24 or 26 teeth, or triples
with big rings of 46 or 48 teeth: in other words, Joan Oppel-style
gearing! That is to say, the sort of gearing you will find on most
Rivendells.
I remember when boutique wheels came on the scene. There was a bunch of
guys in my bike club who always rode together. First one, then the
next, eventually one by one, they all switched to high-zoot boutique
wheels. It was an arms race, with the goal of being the fastest in the
pack. When it was all over, everyone was in exactly the same position
in the pack that they'd been in before, but collectively they'd spent
enough on wheels to buy a new car. But they all felt FAST. And looked
PRO.
Unless you spend a lot of time robbing convenience stores or at the drag
strip, just how often does the need arise to "get going NOW"?

The usual comment you see on the forums is "triples are too
complicated." Can't say I ever understood that.

Here is my experience with gearing and mortality.
Some ~25 years ago I was riding a custom bike built by Dave Porter in Albuquerque, NM .
The bike had Campy Nuvo Record parts.
As I recall the double crankset was a 50/42. The seven speed freewheel was a 13-26.
In those days this worked fine for me for climbing to the Sandia crest( 5k vertical).
Riding the high mountain passes from Durango to Silverton, Co was great fun. Doing fast centuries was a blast
I loved that bike and continued to ride it for many years. As I entered my 50's and then 60's I gradually discovered that
I was no longer interested in or capable of climbing steep mountains or hills.
Getting a carbon bike with a triple and then a Rivendell with a triple and even lower gearing was my personal
cycling renaissance.
A reason that 'most mortals' often end up on racing bikes with inappropriate parts (high gears/skinny tires)
is the narrow way that bicycling get promoted and marketed.
All racing, all the time, is not a great foundation for a life long sport.
That's my story and I'm sticking to it,
-JimD

Funny, usually they start telling me about how it takes forever to break
one in and how you need to use a ball peen hammer...

Which is fine. For some terrains, for some riders, a compact double is
just the thing. But riders who either skip roads because they don't
have low enough gears, or who zigzag on hills they ride, need lower
gears.
With STI shifters, which are ubiquitous in the high-end road bike market, shifting with triples has always been finicky. Recent STI seems better, but still not as simple as it is with friction.
Like DougP said, road triples have just a 30t low (and a 50t or 52t big ring). I assume it's customary to combine that with a 12-27 so chain wrap considerations don't cause problems. With the compact double and a 34t small ring, you could more easily use a 11-32 or whatever without chain wrap being such an important variable. Therefore, the low gear in both setups may be similar.

Personally, for grades over 12% that go on at that steepness for a mile
and a half or two miles, I like to have a 22" gear. I might not stay in
it for the whole distance, but it sure is nice to have it. 24 front, 30
rear will give it to me. This is on a 24/36/46 110/74 triple that most
of the time is used as though it was a compact double (that just happens
to have a third granny ring).
It's easy to get good gearing with 9 speeds. It's a bit more difficult
with 10, or at least it was until recently. In the past year or two,
SRAM has released the Apex system which has 10 speed cassettes that go
to 32, 34 and maybe even to 36. google results are inconclusive: I can
find 12-36 for sale, allegedly, but can't find a listing on SRAM's site
for them and nobody can tell me what sprockets come on it.
It's also curious what sprocket combinations you do find. The 11-32's
gears are reasonably well spaced, except that the 11 is too high; but
the 12-32 has a gap between the largest and next to largest sprockets
that's large enough to fall into and get lost.
I know Shimano has some 10 spd Mtb cassettes now, but can't find out
much about them: are they in fact compatible with road shifters or with
"old" Shimano MTB rear derailleurs?

They stopped because Shimano changed the way the cassettes were
constructed, and taking the current models apart is too labor intensive,
requiring grinding. I believe if you want to, you could do the grinding
yourself and make your own custom cassettes.
You know, there's a really nice standard 7 speed 13-30.
