New bikes are lighter. Faster, well, as ever that depends on the rider not the bike.

531 isn't really in use for race bikes any more - it's too heavy.

20 years ago a standard race bike would be 22lbs and a super-light, somewhat fragile bike could be
19lbs but wouldn't be up to the job for regular use.

Now a standard race bike is 19lbs and a super-light, but still strong one will be 16lbs (Trek Madone
for example).

The newer gears are lighter dispite more cogs. The combined brake/shifters levers are now as light
as the old brake levers were after a long time in which they were heavier.

There was a period when bikes got heavier, mostly due to STI/Ergo units being heavy, but they are
now very light.

Frames of equivalent cost are generally lighter now. The best modern clincher tyres are slightly
faster. Rest of components, I'm not so sure....

I've completely rebuilt my 1980's "fast" Raleigh Royal tourer with modern equipment of the
equivalent/higher price level and it's now *heavier*. Probably the only things that are now
substantially lighter are the handlebars and headset. Dual pivot calipers are heavier than Weinmann
centre-pulls, more sprockets equals more weight, MA2 rims no lighter than old Rigida/Weinmann
alloys, Ergo combined brake & gear levers heavier than old brake levers plus DT levers, cranks still
solid lumps of alloy, etc, etc. However, the better comfort and function makes the bike more
enjoyable to ride than it ever was with the original spec, and the wider range of closer-spaced
gears makes it faster, because I can ride more efficiently, despite the ageing of the engine!
Clipless pedals help as well.

Always. Even if they weigh the same ;-)

Carbon forks and the threadless system saves a lot of weight. I reckon modern mid-priced racers
are faster.

Of course new bikes are faster, unless purchased for a different property such as foldability. The
effect of buying a new bike virtually expands mental perceptions of distance and slows perception of
time to result in increased speed as a direct consequence of spending a lot of money on it ;-).

They are probably a few pounds lighter than some years ago and are thus 'potentially' faster. The
cyclist must still be the most important component. I only ride mountian bikes and the upgrades from
an origional old Boss thing to the current Marins has produced an impressive improvement in
handling, braking and gear changing. These changes make me faster (a comparative term) but more
importantly make the whole plot a more enjoyable ride. I love new technology and take advantage of
it - but I do realise the principle limitation is me.

_Everyone_ knows that _red_ bikes are fastest.

Made me chuckle

My new tyres convinced me I was faster, however my average speed is still the same. I thought that a
long time on tyres flatspots them all around, therefore more tyre on the road. Then I realised that
I was just giving it more

Is the correct answer. What other reason whould there be for buying one? :-)

I didn't really try to get a lightweight when I built my road bike 14 years ago. It tipped the scale
at just under 20lbs when new.

The key things that got the weight down:

I am short so a 50cm 653 frame is pretty light. I have short legs so 165mm cranks save a few grams.
competition 19mm clinchers and latex tubes.

With a bit of work I could have probably dropped the weight by another half a pound by trimming the
saddle, seatpost and handlebars. Then again losing a kilo off the bike won't make much difference
when I weigh about 90kg (though this is dropping rapidly, I was pushing 105kg last summer and quite
unfit) which is a bit much for my shoe size. (OK, I have a not so nutty theory that obesity charts
should be based on shoe size rather than height. That is partly because when I was riding 200 miles
a week, fit as a fiddle and had just got back from a month walking/climbing in the dolomites I
weighed a tad over 70kg which puts my 165cm into the 'seriously overweight' category. Total bull.
Yes that does make me a 'stocky' build but my target weight of 80kg is generally right for my shoe
size of 9.)

The thing is that an equivalent bike now (owned by someone who choose the components with weight in
mind but without megabucks) would be 17lbs....

Someone with megabucks can make a 15lb bike pretty easily (carbon forks, carbon wheels, carbon
crankset, carbon bars, carbon saddle, carbon seatpost, super-light Al or cabron frame...you get
the idea).

So when I replace my ageing road bike with something that can take mudguards and a rack, 27 speed
STI, I should be able to get something about the same weight..? Being the son of a metallurgist I am
more likely to go for a steel frame and forks than aluminium and carbon. I'd like the bike to last
another 20 years.

Sorry to repeat my usual chant .... but would 2lbs really make you go that much faster?

(OK, enough to make a difference in a serious race)

Quite right! Color is critical.

The disappearance over time of all of those British Racing Green and dark blue bikes has upped the
average speed of the worldwide fleet. But the real advances have come with the Cannondale "Bad Boy",
carbon fiber, and all the other all-black bikes. Everyone knows that black absorbs more sunlight,
which makes the molecules vibrate faster. The resulting kinetic energy makes the bikes lighter and
also stores forward momentum. These days I always lock my black bike -- not for fear of theft, but
just to keep it from running away.
