Chris Hansen said:Hello,
I've talked to several people who have talked about how
bicycle technology has improved in the last 10-15 years. I
realize that mountain bikes have come a long way and that
shifters and brakes on road bikes are fancier now but it
was also mentioned that drivetrain components and wheels
and stuff are a lot better. I was just wondering what that
means by being a lot better, what has changed? In terms of
rolling resistance, is it worth upgrading wheels or tires
if the ones you have are still in good shape? I keep
wondering if the new stuff is really that much better?

"It's a Schwinn LeTour, I think about 10 or 15 years old.
CroMoly frame, index shifting, 27 inch wheels. It looks like
it has alloy wheels, I don't think they're original. It
looks like it's pretty solid but needs a lot of cleaning,
lubing, adjustment, etc.
I plan to use it for commuting this summer and I'd like to
take it on the MS 150 in June."

My impression of the Schwinn Le Tour is that it was a good,
solid bike with very reliable medium-grade equipment.
Nothing fragile, but by the same token, nothing super-light.
It's the kind of bike that will last pretty much forever.
"Significant" improvements? Well, index shifting replaced
friction shifting - but you've got that.
Cassette rear cogs replaced freewheels. That makes it easier
to replace worn cogs, and makes your rear axle a bit
stronger, but it's no big thing.
Triple cranks are more common. That's a big improvement if
your hills are bad enough.
Pedals became "clipless" which most people like, but you can
add those easily. (I've never bothered.)
Saddles have grown holes. Lots of people find those more
comfortable, but it's a very individual thing.
Brakes went from requiring three fingers for a panic stop,
to allowing only one finger to throw you over the
handlebars. I see no advantage there.
Handlebar stems and headsets went from slow-assembly, very
adjustable to fast-assembly, less adjustable. Here, we
sometimes argue about whether that's an advantage.
Shifters went from simple devices mounted on the frame (or
handlebar ends) to unrepairably complex devices built into
the brake levers. We argue about those, too.
Metallurgy got better, and manufacturing techniques got
better, so frames, handlebars, seats, all got a bit lighter.
That's nice, but not usually significant (see below). In
some cases, those parts became "stupid light," meaning
you're expected to replace them just before they break, and
you're expected to know when that will be. Either that, or
just buy a new one when the old one's no longer fashionable,
to be "safe." That's detrimental.
Most other changes (like increased gear count, or arcane
changes in chain design) are not very significant.
Regarding weight: A lighter bike will make it a little
easier to climb hills faster, and easier to keep up with the
pack of racers in a sudden sprint. But in most cases, it
won't make any significant difference in your commuting
time, and it won't make you any more comfortable at the end
of the MS 150.
I'd say make sure the bike fits your properly. That's more
important than anything. And check the wheel rims with a
magnet, to be sure they're not steel, because steel rims
cause terrible braking in the rain. If they're aluminum,
they're fine.
Replace the tires. Slicks really are better. Replace the
brake shoes. "Cool Stop" brand is best. Give it a complete
tune up, including truing the wheels.
Then ride. The more you ride, the better your bike
will perform.
