Summary: ya can't be sure.... 

Someone sometime ago posted on this topic that they decided which
way to put the BB axle in by looking at the manufacturer's
logo/size/whatever stamped on the centre portion - read it as
though you were sitting on the bike and the correct end will
be on the right for the crank.

Welllllll, I just got a replacement axle for an admittidly older
crank (TA) and it is (thankfully) obvious which end goes where
because using the logo/size method the old one and the new one
are opposite.  The new one makes me read upside down.  A shame, 
I thought the original poster had a great idea.  The nice thing
about standards etc...

I tend to agree with Bob on this one. I don't think weight should even
be a factor when choosing a saddle. The only thing that matters is
comfort.

I have a question though - can these seats bear the brunt of a spill?

Any unfortunate souls who can answer this?

I never never quite understood why this matters.  If someone runs me
down with a car, I'm not likely to care whether it was a result of
DUI, speeding, or general incompetence.  Its the results that matter,
no?  Why should someone who hits a pedestrian when sober get off
any easier than someone who hits a pedestrian while drunk?  I think
people should bear the same responsibility for their actions in
all cases. Having a bible in your car does not reduce your responsibility
for hitting someone.

Now THIS rings a bell. At one time, a bike dealer almost didn't want to
sell me Sheng Shin tires, because he claimed they would not work
properly on hook-bead rims such as Mavic's M-3.

Odd. I'd forgotten all about that incident. I'll have to see if I can
dig out some old Sheng Shin tire from my junk store and have a
look-see. Maybe the problem is simply that they don't have a proper
hook-bead and thus when the pressure from the tube forces the bead to
go in the groove of the rim, this causes too much stress on the
sidewall.

-If cost is no object then buy Ultegra with dual control shifters.  They work 
well and are probably the wave of the future.  On the otherhand they are heavy, 
complicated, and expensive.  That makes me nervous.  Ride the bike and see if 
its worth it to you.
-105 works as well as Ultegra or even Dura-Ace.  Its not as durable or as 
light.  Ultegra is just as light as Dura-Ace and almost as durable so I think 
thats the best cost-effective choice.

Nahhh.  The Trek that you mention doesn't have that problem, urban legend to 
the contrary.  I had a Trek carbon fiber for several years before it was 
stolen, I'm 6'3" and 220 lbs and rode the shit out of it.  No problems.  I knew 
many people with these bikes in Hawaii, they're very popular there, nobody had 
any problems that I know of.

>Cannondale R900, Performance Focus, Trek 2300
I would strongly reccomend against the Peformance bike for two reasons;
-just about everyone on this newsgroup who has dealt with Performance has had 
problems.
-buy a bike from a local shop that is willing to support the purchase with any
warranty fixes etc. that are necessary.  if you bring a performance bike into a 
shop they'll probably throw you out.  At the very least they won't be motivated 
to work very hard on a mail order bike.

Cannondale.
I love Cannondales, they are light, stiff and strong.  I had a frame replaced
in 4 days when the seat tube cracked.  (The seat tube problem has been fixed in
newer dales).  They are also much more comfortable than before due to different
tubing, geometry, and aluminum forks.  IMHO the Cannondale is the closest thing
to titanium for the price.
Trek
The carbon fiber tubing is great and very comfortable.  The frame is a little 
heavier than a dale but not by much.  My only problem with Treks is the 
geometry.  I could just never get very comfortable on one no matter what I did.
Ride both bikes and see which you like best.  Thats the only way to tell.

Lately alot of questions have been answered by one person and then everyone

UPS is a lot cheaper, although the price will be distance sensitive and it

Now that I've actually picked up one of these things, I can tell you a little
more about it.

The full pack is an internal frame pack that converts to rear (2300 cubic
inches) and front (1150) panniers.  The front panniers are actually split
cross wise (ie, perpendicular to the bike) and zip together; the two halves
zip on to either side of the rear panniers (again, cross wise) to form the
pack.  The whole thing is huge - a real mountaineering pack.  That much is
$345.  For $265, you can get just the rear panniers/pack, which is appropriate
for long day hikes or overnighters.  The much smaller rack/fanny pack is $39.

It seems very well designed (he has a patent on it) and built, with lots of
places to adjust things and fasten things on.

*dan stanger 303 969 3312

I have one, but you can't have it.

Do you know which type you want?  There are three:  Red band, blue band,
and yellow band.  Identified by bands of paint on the center of the hub.

Blue bands are overdrive hubs, red and yellow are reduction hubs.  
Blue bands have brake shoes that press outwards against the inside of
the hub shell, like Bendix coaster brakes.  Either the red or yellow
hubs use the same type of brake (I can't remember which is which any
more).  The other reduction hub uses several discs that are pressed 
together for the brake.  I feel that the first type is superior.

Last I heard Keswick Cycle in Glenside PA still had a couple of hubs
*NEW IN THE BOX*.  I got the last blue band when I worked there 12 years
ago.  They still had a few of either the red or yellow ones stashed
away in the back.  The last of these hubs went out of production around
1969.  I have no idea what they are worth.  If you call them let me know 
how it went.  The owner of the shop is Kenny Norman.   

For those that never heard of these things, they are a two speed hub
with a planetary gear set and a coaster brake.  They are either direct
drive and overdrive/reduction drive depending on the type.  To shift
gears you backpedal slightly.  No shift lever.  They are very strong
and very heavy and very cool for a cruiser type bike.

Sure. I'm one of the (few remaining?) people who use a chain and padlock.
When I lock up, the chain goes around the post/tree/whatever, through
the frame and both wheels, then the padlock goes around the seat rails.

Conductive heat rejection is proportional to temperature above ambient.

There is evaporative heat rejection, too; different rates of sweat evaporation
will not show up in IR camera pictures.

Agreed, so far, and I might add that I think that is an important part of
the reason knee problems are worse on uphills.  One can't as easily lighten
up on whatever part of the stroke is causing the pain, as gravity will cause
a large variation in speed during the pauses in power input.

But what I don't understand is what 'acceleration losses' are.  The
power needed to move the bike+rider up the hill is constant, regardless
of any velocity variations. (velocity variations might affect total power
into aerodynamic drag, but on a hill, that is relatively unimportant)
Sure, as you accelerate you do work to store kinetic energy
in the motion of your body, and the rotation of the rims, but that
energy is used to move you up the hill during any pauses between
power strokes.  It is not lost.  

I think that the reason for using a longer stroke on hills 
and so avoiding cyclic speed variations is not that there are 
'acceleration losses,' but either that it is unpleasant and disconcerting
to have wide speed variations, or that they actually get to the
point where it is hard to balance the bike during the slowest parts
of the cycle, or there is a danger of starting to roll backwards
(which could entail power losses, and other sorts of losses as well.)
