A few days ago I posted an article concerning a problem I am experiencing
with gradually sliding forward on my saddle.  Since that time I have
received many requests for a summary of the responses I have received.
It would seems that this is a rather common problem.  The response below
was the most comprehensive and included all the info contained in the other
responses.  One additional suggestion was that my frame size might be too
big causing me to overreach for the bars and therefore slide forward on the 
saddle.  Hope this infomation helps all who requested it.


Most of original post deleted for brevity.

Saddle height: It should be around .883 (According to some "experts") of
your inseam (without shoes). The distance is measured from the center of
the bottom bracket to the top of the saddle parallel to the seat tube. Some
people use other numbers but I find .883 to be a good starting point.

Now, this approach of determining seat height is less vague than the one
you described. Be carefull not to put it too high (in which case you'd
start rocking on the saddle every pedal cycle).

IMPORTANT: your particular problem might not have anything to do with the
height. THere are three possibilities I can think of:

1. Most probable: Your seat is tilted downwards on the tip. The normal
saddle position is horizontal (i.e. the line joining the tip and back of
the saddle should be horizontal). Many people (me included), prefer to have
the tip of the saddle pointing slightly up. This would prevent sliding
forward when in the drops (I ride a road bike).

2. Your seat is too far backwards. The rule of thumb to determine fore/aft
position is that when you are sitting on the saddle a plumb line taken from
your knee (side of the patella) should go thru the pedal axle when the
pedal is in the most forward position (three o'clock). 
 
3. Your stem is too long. Once the seat is properly located. If you are
with both hands on the hoods (on a road bike) the handlebar should obscure
the front hub. You might need a shorter or longer stem.

4. (well not three) a comb of all of the above.

Some people believe "chain suck" is this result of poor shifting, but I
disagree because it happens to me even when not shifting. I've had the chain jam 
in between the chainring and chainstay on occasion when the drivetrain has
accumulated alot of mud and dirt on a particulary mucky ride. It's my guess
that a "paste like" mixture of wet dirt wedges in between the chain link and
chainring teeth and if the drivetrain is in a low enough gear this "stiction"
overcomes the tension being exerted by the rear derailleur pulley/cage. Thus
the chain link will not release from the chainring and the chain gets hung up
on the chainring as it rotates around and the chain gets pulled up and forced
into the nasty little space in between the stays and the ring.

There are a couple of widgets on the market which mount under the chainstays
and act as a barrier (cover the space between the stays and the chainrings)
so that the chain can't jam. Trek makes a steel plate that sells for about 
$5 and Ringle makes one that sells for as much as $40 (very trick and way
over priced). If the Trek one doesn't fit your bike, I'd bet that with a piece
of scrap steel, a hacksaw, and a little work on a bench grinder, you could
easily fabricate one of these yourself (or make the Trek one fit).

BTW some people claim that if you take a Shimano Sharkfin Chainstay protector
and mount it upside down under the chainstay, it'll work as an antisuck device.
I tried this and it didn't work for me, because the first time my chain got
hung up on the ring the pedaling forces were too much for the vinyl/rubber
chain stay protector and it just spun right around and let the chain jam.

I am amazed that this whole subject is so wrapped in rumor.  The
only credible response that I received was that Power Bar is labeled
"meal replacement" and that this implied it is equivalent to a
healthy meal.  Because outdoors suppliers make packaged food that
tries to be a meal replacement and is so labeled, the Canadian
government has required those manufacturers to either include the
required nutrients or desist from the labeling.  These suppliers
justly complained that Power Bar was also labeled "meal replacement"
and demanded equal treatment and they got it.

It would be nice if this scenario could be corroborated.  It is the
only one I have heard that seems to make sense.

Organization: Digital Equipment Corporation
Date: Thu, 13 Aug 1992 14:28:12 GMT


	Anybody know the correct procedure for setting up a Shimano Rapid-fire
 shifter/front derailler. Do you start with the barrel adjuster on the shifter
 screwed all the way in or out a few turns? How much clearance is needed for
 the derailler? HELP!!

	The problem I am having is that no matter how I adjust the damn thing,
 I just can't seem to get it "perfect". It's indexed ONLY, so it has to be 
 right. What happens is that in the middle ring, the inside of the derailler is
 too close to the chain and rubs slightly when I'm in the lower gears. I can
 get it to shift up and down to all three rings and I can get it to not rub
 in the lower and higher, but I CAN'T seem to get it so that when I shift
 up from the small to the middle ring, the chain is centered in the derailler.
 Does anyone know where I can get the correct Shimano set-up procedure, or does
 anyone have a copy that they'd be kind enough to mail me. Thanks.

But my problem with this is why would we want to tax some other section of the 
population in order to force us (cyclists) onto a more dangerous and less 
convinient system (bike lanes and paths)?  I guess it could be argued that it 
would be a 'fair' system in that all would suffer.  If one wants to tax motor 
vehicles in order that they pay more towards the real costs of their use, fine.
However if that makes for fewer vehicles on the road I don't want those roads
to be closed to bicycles (and if you use gas taxes to finance bike lanes/paths 
you can be sure that motorists will demand and get such, which many motorists 
are already doing).

As far as I know all of the monitors have a high and low alarm and they are 
a good way to keep you from slacking off when training (especially
alone).  I would agree that basic models, like the Polar Pacer which I
use, are all that you need, unless you didn't already have a cycle

You shouldn't have any problem doing this.  I didn't.  Go ahead and use

The label "redneck" should only be applied or assigned as the result
of observable behavior.  It does bother me when people gratuitously
include "woman driver" or "old lady" in their accounts of accidents or
close calls.  If they explicitly made sweeping generalizations, I
might be inclined to respond or flame.  The abuse Jobst and Greg

Naw -- because this generalization (though wrong) doesn't imply

The point is, if I managed to include you in a sweeping generalization
that suggested you, personally, made riding less safe for everyone,
this would likely strike a nerve with you.  Do you drive a car?

Actually, I don't think Poulidor placed second in the Tour more than once,
twice at the most. He does hold the record for the most top three placings
without a win though, something like eight.

Joop Joetemelk is the Tour bridesmaid with a whopping six second places. 
He also had a couple of thirds (I think) and finally a win. One thing a
lot of people don't know is that when he was reaching his potential he
got very ill or had a bad crash (can't remember which, think it was the
former). It was thought his career was over but he came back. It is said
that he missed his best years because of this and whether Eddie Merckz
would have (could have?) still dominated with Joop is questionable.

I have to disagree with this. I'm 6'2" and I thought my 22" was just 
too damn small for me. I've got the seat jacked up to the moon for
riding comfort.

You better have your friend test ride different sizes and let
