While you're at it, please answer the following:

The device that provides the motive power for something "drives" it.  The motor
DRIVES the compressor, etc.  

When you passively sit in a vehicle such as a train, you "ride" it.

EXCEPT for the two most commonly used [?] vehicles in the USA:

You DRIVE a car, and RIDE a bike.

Subject: Stroke Efficiency Experiment
Date: 14 Apr 92 19:51:51 GMT
Organization: HP Santa Rosa Site (NMD MTA MWTD). - Santa Rosa, Ca.

Yesterday, since I didn't have time to do a real ride, I took out the
dreaded rollers to do an experiment I thought of a while back relating
to pedalling efficiency.

The controversy is over whether it is more efficient to pedal using
a predominantly pushing motion or to share the load among more muscles
by using a rounder stroke, meaning trying to exert force on the
pedals throughout the full pedal revolution.  

The more efficient stroke, by my definition, would be the one that 
results in a lower heart rate while going a constant speed.  (Another
way of stating this is, which combination of pedalling muscles will
convert a greater percentage of metabolic energy into forward kinetic
energy.)  With variations in wind and terrain, the open road isn't the 
best laboratory so I chose the rollers.

What I did was just ride at as constant a speed as possible using the
two strokes and observe any difference in heart rate.  After warming up
for 10 minutes or so I used a 53x13 and rode at 28 mph as constantly as
I could.  (Remember, this is on rollers with no added resistance.)  I
consciously switched back and forth between the two pedalling styles 
several times.  If there was any difference between the two resulting
heart rates, it was not obvious from this casual experiment.  My HR
stayed around 138-142 for both styles.  I found that there was enough
delay in the feedback loop to make accurate speed control and up to
the moment HR observations nearly impossible.  If my speed dropped just
.5 mph, the smallest measureable change, and then I began pushing harder,
the HR still remained low until I had achieved .5 mph too fast.  Then
the HR would go up while I was trying to slow down.  Maintaining a 
constant HR and observing the resulting speed had the same consequence.

The best I could do was stay at 28 +/- .5 mph and observe a range of
heart rates.  A couple of times I saw my HR go up a bit while using the
round stroke.  But then I noticed that I was tensing my upper body in
the effort to force what is for me an unnatural spinning style.
When I relaxed and breathed easier, the HR went back down.  

The most I can conclude is that, for me at least, the difference in
efficiency of the two strokes is too small to measure this way and 
probably too small to be important in open road spinning.  I think that
this only holds for spinning.  Very high speed, intense hammering and
steep hill climbing may be another ballgame and one that I can't simulate
with no-load rollers.  I'll continue to spin using my lazy pedal stroke
because the effort of 'thinking round' all the time is mentally taxing.

Back to rafters with the rollers, it's sunny and warm outside!

toe holders together while saying "I wish I was a real man" over and
over again, your ten speed will sprout cylinders and be a moped, maybe
some-one will just run you over while you run a stopsign.

Bicyling Magazine put out a book named something like 
"Nutrition for the Bicyclist" which devoted several
pages with charts and formulas to this topic.  I bought
it at my local bookstore for about $8.  The other info
that it contained was worth many times my investment.

While I do not have it with me, I do remember that it 
said that when I pedal my 195 pound body (bike weight
may or may not have been in the formula - my bike weighs
20.5 pounds + water bottles etc) at an average speed of
18 mph on only slightly rolling terrain that I was
supposedly burning about 700 kcal/hour.  I am guessing
that you are burning about 500.

After a long time of deliberation I decided to get myself a pair of Look's.
I chose the PP56 (1991 model), the choice was determined by budget and
other factors. Anyways, I just tried them out indoors to see how they feel
(in my living room), I will go out in my usual training ride on Sat or
Sunday and try them seriously for the first time. I am using the ARC red
cleats. 

Anyways, my question, if you sprint real hard, or if you pedal (standing) up a
hill hammering real hard, how likely is it to get the shoe off the pedal
unintentionally? I ask because it seemed to me that unlocking yourself from
the pedal was very easy, a bit too easy to my taste. Unfortunately (this is
the first drawback of having bought the cheapest pedals), the 56's don't
have adjustable release tension.

Thanks for suggestions.

Well, we have all listened to endless bantering about cars hitting
bicycles etc.  

First, I bike all the time -- everywhere --- even though I have a nice
Volvo.  I even get my groceries on a bike. I commute on my bike -- I even
ignore the rules of the road a lot -- and run stop signs etc.

How about the penalties for bicycles hitting pedestrians?

I am looking at the local paper.  There is a picture of a girl --- 
complete with neck brace -- sprawled on the pavement after being hit 
by a bicyclist.  The biker is standing next to her,  covering his face from
the camera.  He was cited for failing to yield to a pedestrian.

I also remember being in Minneapolis years ago when a bicyclist hit a
walker on the path around Hennepin.  She died. As I remember it she was
the wife of a local V.I.P. (possibly the mayor).  He did not go to jail
either.

Mistakes happen -- but he is going to get off FAR to easy.  

And --- what about the crazy people riding on bike paths as if they are
the only bike on earth  --  never looking ahead for oncoming bikers.
I think bike paths are pretty dangerous because --- when there is not car
bikers feel -- "Hey, we can go hog wild and fancy free".

No.  However, let me say that, despite what the law says, most
bicyclists will appreciate it when you do NOT use your horn.  We can
hear you just fine--especially here in the Commonwealth of
Massachusetts, where there must surely be a law against the use of
mufflers on motorcycles.  If the cyclist is EXCESSIVELY far to the
left (with no obvious potholes, debris, etc. to the right), or is
driving in an erratic manner, then a horn signal may be appropriate,
while still a reasonable distance behind.  Otherwise, please pass when
safe, without using your horn.

Regarding cyclists and drivers:

	I was regularly riding a  60 mile route between
	New Hampshire and Cambridge, Ma.  This was on 
	about 80% back roads with no or minimal shoulder,
	on weekdays between 7 a.m. and 10:30 a.m..

	Lot's of commuter traffic.  I did a quick count 
	over several sections one morning and estimated
	that I was passed by ~1000 cars each ride.

	At least 30% of these drivers were noticeably
	delayed by passing me, no matter how well I
	rode.

	The point is:  if 99% of the drivers behave
	perfectly, 1% behave stupidly, and .1% behave
	criminally or marginally criminally - you'll
	get:  ~10 stupid passings per ride and a
	genuinely scary encounter at least every other
	ride.

	So, all dogma aside, a cyclist encounters a very
	large number of vehicles (under some conditions)
	and his/her perception of how drivers behave is
	dominated by a relatively small percentage of 
	drivers.

Some method for keeping your foot on the pedal (and therefore keeping control  
over your bike) is a must.  Toe clips and straps work just fine.  It can be  
hard sometimes to get your foot back into the toe clip if your on a hairy  
uphill single track.   PowerGrips are a little easier to get into/out of.  I  
just switched over to Shimano SPD clipless and have been pleased so far.  Make  
the investment in toe clips and some decent stiff soled biking shoes.   If you  
really wipe out...you'll come of of the pedals, don't worry!

I thought that the aluminium oxide was a very good protection agains futher

All new aluminium parts what was installed on the boat should not be painted
before the part got a good oxide layer on it because the paint will stick
better to the oxide that to pure aluminium.

   Does anyone have any strong opinions either way about DiamondBack bikes?
   Are they worth the price?  I just bought a DiamondBack Approach hybrid for
   my wife for around $300 "on sale".  Although I like the way it handles and
   the grip-shift feature, the paint job on the frame is pitiful.  I was told
   a new one could be ordered, but chances are, the frame would not be perfect
   on the new one either.  My Trek 800 was only around $50 more than the DB, and
   its' frame is perfect; not a mark on it.  Am I just being nit-picky, or is
   the poor finish on the DB an indication of the overall quality of the bike
   (no insinuation intended; just an honest question)?

I own a 1991 DiamondBack Master TG road racing bike. It's been quite
servicable for entry-level racing, but it had a problem which caused
me lots of grief: the handlebars would rotate in the stem. I took the
bike back to the shop several times, where they knurled the
handlebars, tighted the handlebar binder bolt with superhuman
strength, etc., with no luck.

Finally, browsing through the Excel catalog, I discovered the cause of
the problem. The Tioga T-Bone stem takes bars that are 26.0 mm
diameter... the "Centurion" bars that came with the bike are 1 inch (25.4 mm)!
New 3T handlebars (which are lighter anyway) fixed the problem.

I don't know if this was DiamondBack's fault or the shop's (Guthrie Bicycle
in Salt Lake City). I've heard that 1 inch handlebars are used on
lower-quality bikes, so there might have been some mixup during
assembly.

I would say this bike's paint job has held up alright, considering the
abuse the bike takes. 

That said, my girlfriend's Bianchi Alfana is far nicer for the same
amount of money. I wish I had bought one instead of the Master.
