What type of biking are you interested in?  I live in Huntsville, Al (about
1.5 hours south of Nashville) so I'll give you a summary of what I know.

USCF Races can be found in Memphis, Chattanooga, and many smaller towns
around Nashville.  There is also Interstate access to alot of races in
Atlanta and N&S Carolina.  I almost forgot Knoxville and Johnson City.
There is racing in Kentucky also as well as Arkansas.

Mountain Biking is done quite a bit in this same area but I'm not a mountain
biker so all I can tell you is yes, people mountain bike a good bit in the
area.  Ellijay Ga. is a good place to start.

Hope this helps or at least provides some encouragment.

Howdy!


I was wondering what effect riding down stairs on a Mountain Bike can have on the bike.  I ride around on my campus a lot, and in many situations it is just easier to go down a few stairs than to go around a building.  Am I screwing my bike up gradually?  Nothing seems to be greatly effected.  Any comments?

Summary: Can it be done?
Date: 7 Apr 92 14:24:47 GMT
Organization: The University of Texas at Austin, Austin TX

Sorry if this is a FAQ or was just answered yesterday...

Well, I finally broke down and made the switch to duraSTI and 8spd. 
:-) 

I looked at the instructios for my new Ultegra hubs, and it looks like
the mounting system for the cassette is like that of 7spd hubs. Which
looks promising, from the number of 7 speed Dura Ace cassette hubs I've
got.

So my question is: If I buy a new 8 speed cassette body and a 130 mm
axle, can I convert my DA7's to DA8's??? (I realize that I'll have
to get new cassette cogs.) More important, does anyone have the
Shimano small parts numbers for the parts I need?

On a related topic: Has anyone had success drilling out the rivets holding
the top 6 cogs on a Ultegra 8speed HG cassette? I miss not being able
to do any funky cog combination my heart desires....

Thanks!!!!

The Trek is a good bike but as I have  mentioned I could never get used to 
their geometry.  The Cannondale is an especially good deal because you get 
their full 3.0 frame with aluminum fork.  The Trek has a chromoly fork and is 
heavier and less shock absorbent as a result.  The RB-2 is a great bike but is 
heavier than the Trek or 'dale.  It has fantastic geometry with crank and stem 
correctly sized for the frame size.  its hard to pass up that light 'dale frame 
though...

>I'd especially like to know about the difference between Treak

I don't think either one is really.  The bonded frames are supposed to be 
slightly more shock absorbent because the glue absorbs some shock.  however 
this is probably negated by having a chromoly fork.

The thing to remember in this bike category is that the frame is the most 
important thing.  You can always upgrade components.  If price is important and 
weight isn't then the Bridgestone is an excellent buy, what is it about $580?
IMHO you need to buy at least the Trek 1400 to get a bike as good as the 'dale.
In the long term I would go for the 'dale because of the high-quality frame and 
low price.  Ride each of these bikes several times before you make a decision.

I don;t know aboput you, but the only bike tht I can find that will fit

length, tells me that I need a 66.5 cm frame  I think that I would like
a bit larger bike, like 69, but if I can find one long enough top tube
wise I guess the seat tube can be accounted for with a 350 mm seat post,
like my 22 in cannondale mountain frame.(I always get the tree seatpost

Anyone who travels in an outside lane when inner slower lanes are clear
of traffic is an idiot. Anyone who is forced to travel in the outside
lane for some time because there is so much traffic in the slower lanes,
and who is not keeping a watch behind for people travelling much faster
is an idiot.

If any vehicle EVER passes me which I hadn't previously observed
approaching, and noted as a potential passer which I was watching
for, I regard this a black mark against my observational skills, and try
to work out what I did wrong.  It does happen in the hurly-burly of
urban rush hours, despite my best efforts. It very rarely happens
outside of the rush hour. If THREE vehicles ever came up behind me which
I didn't know about, let alone FIVE, I'd immediately diagnose myself as
being dangerously unfit to ride and start looking for somewhere to stop
and take a break.

It is also dangerous to look over your shoulder in fast close rush-hour
traffic. That's why I have spent some time finding and fitting the best
possible mirrors, and why I would never tolerate a bike/mirror
combination which vibrated at ANY speed.

Why do I go to all this bother? I know several ex-bikers whose injuries
mean they will never ride again. I enjoy motorcycling too much to risk
that.

Subject: Re: Valve Nuts
Summary: I'll refrain from putting the obvious suggestion here
Date: 10 Apr 92 18:39:27 GMT
Organization: AT&T



Don't give up on valve nuts!  I have shared your experience with the post-flat
stuck valve nut.  I have gotten into the habit of loosening the valve nuts
after filling the tires.  The valve cap should prevent loss.  The valve
nuts are still valuable in two ways and maybe a third
way (if you can attribute some value to folklore):

1) when you are mounting a tire, the valve nut can be secured (finger tight)
so that the empty tube doesn't slip around the rim.  The result would be
a valve exiting the tire through the rim hole at a crazy angle.  The
result is not always possible to correct after the tire and tube
are fully mounted.  When the tire and tube are fully mounted on the
rim then unscrew the valve nut and push the valve into the tire.  This
helps ensure that the tube is not between the tire bead and the rim
in the vicinity of the valve (you have to check for this condition
visually everywhere else around the tire or else employ a mounting
method which guarantees no "pinch").  Pull the valve back out and
screw the valve nut back to the base.

2) If you flat without a pump and have to walk, the valve nut (even loosely
secured) will prevent the tube from rotating around the rim.  This result
may seem to be inconsequential (after all, "the tube is flat--what good is
it") but you may want to patch the tube.  A long walk with a flat tire with
an unsecured valve can result in the tube tearing near the valve hole either
during the walk or later as you try to remove the tube.  Also, you may meet
another rider with a pump.  Sometimes you can ride a slowly leaking tire
for several miles.  If the valve is pointing tangent to the rim, you will
have some tire massaging to do before you can get a pump in there.

3) When you are pumping up the tire with almost any kind of pump--but
especially with the hand pumps cyclists most often carry--it is
easy to break a valve (so I have heard anyway).  Having the valve
secured in place by the valve nut may help prevent this.  You sometimes
have to stop pumping and screw the valve nut on some more because as
the tire pressure builds, the valve gets pushed farther out towards the
center of the wheel (you are already acquainted with the reverse process).
This may be myth.  I have never observed it; only read about it. I always
make sure the valve nut is finger tight when I am pumping the tires
(I guess that means I believe the theory).

	Bored surfers?  A not too subtle slam at California?  First of all,
not all Californians surf, and secondly, the early NoCal mtn. bikers were
roadies (not surfers) looking for something to do besides riding pavement, and 
thirdly, surfing is not boring.

	I don't believe any of the early NoCal mtn. bikers considered what
they did "a real engineering design feat".  They just got tired of real heavy
bikes and had Joe Breeze build them a cro-mo frame.  Design feat no, using 
availiable technology yes.


>They had a lot of fun.

	Compared to what?  Road biking?  Downhill skiing?   Ski diving?   Scuba
diving?  Besides, considering how much time those guys spent scouring the 
countryside looking for replacement parts, and the time they spent maintaining 
and repairing their bikes (remember, repack hill got the name because after 
riding down it, the rearhub needed to be repacked with grease because the hubs 
became so hot that the grease ran out), I really don't consider early mtn. 
biking a cheap thrill.  As far as I'm concerned my time is expensive, and I 
don't like spending it working on my bike.  I rather ride my bike.  Also,
considering that a decent mtn. bike (not a top of the line racing model) costs
less than 400 dollars, I don't consider it an expensive sport.

Ah.  A skeptic.
Well we are almost there.  By measuring the torque at the rear wheel its
now possible to see what the net torque from the legs is and with a bit
of work it should be possible to cobble one of these into the BB so that
you can measure the instanteous torque at the crank.
  But the pointers indicate that there is not a large amount of power
generated in any upstroke and that 9x% of the race is with everything
in a quasti-static condition.  What the tests did indicate was that there
was a positive torque (right leg) between 310+ deg and 210 deg-.  So there
is some sort of upstroke but it is not significant (steady state condition)
in the long run.  EMG's have shown that all of the major leg muscles are in
use and the ankel muscles and lower leg muscles are mainly used to adjust
the angle of the pedal so that the upper more powerfull muslces can direct
the torque in a usefull direction.
  May I sujest (emphasise jest) that you go look up the Jibofo device in
Bicycling from a few years ago.  This involved pushing on your legs with
your arms while steering with a mouth attachment.  The mouth attachment
was properly designed so that it "super charged" the air coming in (you
know a ram jet effect).  You will get more power this way.  But for how
long?  Perhaps you could redirect your exhale so that it provides 
propulsion?  These effects are probably as significant as you think your
"upstroke" is compared to a normal pedaling pattern.

There are also drivers who do see you, but think to themselves: "Only
a bike" as they pull out. Some of these drivers mistakenly assume that
bikes have such miraculous evasive powers that they will simply be
able to avoid the car somehow. Others simply think "I'm in a Volvo
(whatever) and I ignore traffic insects on principle". And there is a
third category who think "Ah, we've made eye contact, so I can pull
out quite safely."

I have been following the thread on pedaling efficiency (I have forgotten
the initial Subject name) and happened to note a relevant article in this
month's Velo News.  I apologize if this has been posted before, as I am an 
infrequent reader of this group and may have missed it.

Lennard Zinnn has an article on finding an efficient bike position.
He cites most of the commonly used formulas and describes the problems
with each.  He also notes the oft-quoted advice of LeMond to pull up on
the back of the pedal stroke.  Lennard, first of all, points out
that this is probably not what LeMond does at all, given his foot 
position at that point.  Furthermore, he cites a study by Dr. Edward
Coyle at the University of Texas where it was found that the best time
trialists pulled up less on the back stroke and delivered more
peak power on the down stroke.

Because athletes are good at what they do, it doesn't mean that they
understand how they do it.  (I cited several examples of athletes who
give explanations that are contrary to the facts in a posting
to this group a few months ago.)  Further, other measurements have shown
that top racers generate nearly all of their power during the down
stroke.  Voluminous citations of advice from bicyclists and coaches
aren't going to carry the day when it runs contrary to actual measurement
and observation.  

It looks like Jobst, the cantankerous old curmudgeon (did I get that
right?), could be right after all.

Specs on the standard Dura-Ace STI 8-speed derailleur are: rear cogs:
max 26T, min 12T, max difference in chainwheel teeth: 14, max total
difference (front plus rear): 26.  This would allow you to run a 13-26
rear and 39-52 front.
