Have you folks considered recumbents?  They take the pressure off your back,
arms, and groin and put it where nature meant it to be, your backside.  No

The same exact problem happened with one of my twelve year old Campy shift
levers. The solution; I went to a local pro cycling shop and bought a
replacement nylon bushing for the lever. Now it works like new. The old
bushing was about half as thick as the new one. A lot of wear can occur
from tens of thousands of miles riding...

You tell us.  My experiences seem to be the same as Tom's. 
My road wheels are more prone to spoke breakage than my mountain 
bike wheels. As a matter of fact, I have yet to break a spoke while 
off-road (knock, knock).

	All of my wheels have properly tensioned double-butted spokes 
w/low-flange hubs. My mountain rims are quite narrow, so the length of 
the spokes, tire size, and riding conditions are the only variables here. 
I would bet that my wheels see more stresses off of the road, so what gives?  

Inquiring wheelbuilders want to know...

I have heard a couple explanations for my clicking and popping.  My
ankle clicks when I walk.  It is supposedly a ligament snpping over a
bone.  Dr. says it is not a problem and there is not much I cn do
about it.  If I put my foot down differently I can get it to stop but
that requires me to walk pretty strangely which is likely worse than
the clicking.

On popping, I was told that it was Nitrogen (and other fun gases)
being pulled from the blood/tissue surrounding the joint when a
vaccuam is created.  You move your joint in a particular way and
voila, create a gap between two parts sucking these gases in.
Interesting concept.  Apparently harmless.  Very hard to say I would
say.

the draw to own a truck in Texas was so strong the thought never

Perhaps the current FAQ should remain as is, but allow junior FAQ's to start

All true, I'm afraid. I rode over to the bridge this morning. Not only is
it surrounded by construction equipment, but there is a huge red sign saying

" RAILWAY BRIDGE ONLY - ABSOLUTELY NO TRESSPASSING! "

I think the fact that some of my friends use this bridge on their running
work-outs made me think that it had a safe side-walk. If you hear about a
long distance runner getting scraped off of the bumper of a Light-Rail train,
you'll know why.

Sounds like the right thing to do. While we're talking about Zanker, I had
a embarrassing experience there today. I waited at the light on 237 ready
to head south, and did my usual trick of crossing on the left hand side
with the walk signal. This puts me on Zanker south-bound, but on the
left hand side. Usually the traffic is light enough that I can easily
cross over to the right, but not today! I found myself (and the guy behind me)
at the Bus depot entrance on the sidewalk of the wrong side of the road, with
a irritated bus driver stopping his bus and motioning me to cross over 
before he made his turn. He had lots of cars stacked up behind him too.
Mea Culpa! I guess I'll DO THE RIGHT THING in the future and cross
on the right side. It just goes to show that apparent convenience is not
a good reason to flout traffic rules.

I used Tri-Flow for about two months, and here in Florida, it's a dirt grabber.

About three weeks ago, I ordered DT's entire cleaning/lub products from Schwab
Cycles.  DT's Clean'it, Shin'it, Lub'it, and Grease'it are excellent products.
They are all bio-degradeable of bio-friendly, the lub'it is a light oil that
goes on wet and dries...the chain stays cleaner longer.

The clean'it and shine'it are both excellent.  Just spray the clean'it all over
the bike and a few minutes later, hose it off.  After drying the bike, use the
Shine'it.  It goes on wet, and you wipe it while it's wet.  The shine after has
a 'wet-look'.  My bike looked better than when I first bought it after Shin'it.

Later dude,
Joe

You're right but it's 170mm cranks which is a very common length for
average sized Road Bikes, but not for Mountain Bikes which all seem to come with 175's...

I think the Davis Phinney "method" is also what alot of people are calling
the Eddie B method. At least when Eddie B gave our club a clinic a number
of years ago this is the method he used to set saddle height..Which also
works out to be just about 109% inseam....and .883 inseam (bottom bracket
to saddle) if you're using 170mm cranks...Gee it sort of looks like
all these methods produce pretty much the same result.. Surprised ? :-O

This is NOT true.  Shimano 8spd cogs are tighter spaced than 7spd cogs.
(I think its 1.00mm vs 1.04mm).  The difference is enough to make
shifting sluggish when using 8spd shifters with 7spd cassettes, and
vice versa.   One poster told of a friend using 8 speed STI who
received a 7spd replacement wheel after a flat.  He tried shiting
in the sprint with STI, the chain skipped and he crashed.

While the lateral play in the jockey wheel will accomodate the 
difference between 8spd and 7spd cassettes, the shifting is definitely
not as crisp.

How can this happen without an efficiency increase?  Example:
1 l O2/min 'burns' to produce 330 watts.  At a 25% efficiency, this is
82 watts into an ergometer.  

Power Out  at AT = AT(as % of VO2max) *

I don't understand this.  Anaerobic glycolysis doesn't produce any CO2.
Where does this extra CO2 come from?  Or where did the O2 go?
The CO2/O2 ratio does increase as more glucose is used instead of fatty
acids.  There is usually a change in ventilatory rate at the AT.  One
attractive but incomplete theory is that the increasing blood acidity
due to lactic acid stimulates breathing.

I think you're confusing a Sedis SL with a Regina SL (hollow link), which
aren't recommended for HG. I have 2 friends that have tried them (Reginas), one with
a Regina freewheel and one with a DA Uniglide, and both experienced poor
shifting performance. The tradeoff is weight (~60g).
