Hi netlanders, I have a few questions to all of you on the subject on
training techniques to improve speed and endurance.  My main objective   
is to improve my speed on the bike, I like distance riding, however, in
the last few years even though my speed have improved, but I think it
can be better.

Question #1:  I heard of interval training on both running and biking,
  anybody have any guide lines on doing this?  Can I safely say run intervals
  earily in the morning, and ride intervals in the night?  Do I do each
  on consecutive days?

Question #2:  How much distance riding should I do, I have already over 1500
  miles riding for the season, is this a good base for the interval training
  should I limit the distance riding I do and concentrate on the intercal
  training for the next few weeks, get the speed up and then do the distance
  riding?

Question #3:  How long does it take before I can see some results from teh
  the different training?

Your inputs are appreciated!

  I thought that same thing because I started with the HG90 chains and then
went to the Sedis ATB.  But now that I have gone back I find that the HG90
shifts better but is twitchy (ie tends to shift up and down every few hundred
km).  Of course the equipment is a bit more worn now (10,000 km since I had a
HG90 chain on it) but the Sedis works well on it.

  I use a cheap small chain tool.  The first two times I tried to use the
special black pin the chain failed after 800km because inserting the special
pin bent the sidewall.  Since then I have never bothered to use the black pin
and just push out one of the normal pins.  This has never given me a problem 
on my MTB or road bike in 3 years.  But I am hesitant about taking the darn
thing off because I have seen people who broke their HG chains.  Most likely
they did not make sure that the pin was centered and the link not binding
when they put the chain on.

>link but it is tricky.  Use a Hyperglide or gold Cycoli chain tool.
  That does help but intellegent application of a cheaper tool works
better.

  Do you have any speculation or evidence of why the chain broke the other
2 times?  How did the chain seperate?

>in spite of the increased failure rate.
  I don't see any reason for there to be an increased failure rate.  I am not
sure what the difference is between the HG90 and HG91.  The pro's complained
about the noise of the HG system and apparently Shimano did some work to
quiet things down.  Maby that is the HG91?  I bought a bunch of HG90's when
they were being phased out and will not try a HG91 for another 2 years or so.
However, when my bike was new and on both bikes after 4 years of use I find
that the HG90 chain is noticably more noisy than the Sedis.  Has anyone used
both the HG90 and HG91 or perhaps compared HG91 to Sedis ATB?

  Hi all,

 I like to thank once again all the people who responded to my request re:
winter riding. I wasn't aware, until now, that such information was contained
in the FAQ, which Chris Boynton Emailed me.  Had I known of its' existence
I wouldn't have cluttered the newsgroup with this rather redundant question.
  While reading through the FAQ (very informative to say the least) I payed
particular attention to the part on setting up cleats, for clipless pedals,
and also the section on adjusting saddle height.  Now to my problem:
  I just recently went from clips to clipless and bought the 105s from
Shimano.  I have a copy of Lemond's Complete Guide and really tried
setting my cleats and sattle position as he recommends.  I set my saddle as
far back as it goes, dropped a plumb line down to the kness and then adjusted
from there.  However, after all these adjustments were made, whenever I ride 
with my saddle in this position , although the leverage is excellent and I 
feel much more powerful whilst pedalling, after a long ride, 80 km+, the next 
day I ALWAYS get small bruises on the sides of my knees and sides of the thighs. 
When i set the saddle more forward I don't get the bruises but, my pedalling
power suffers.  Any ideas what my be causing this bruising?  It's not that
Im overly worried about the bruising, I mean they do eventually go away but,
I'm just curious to know if this is "normal".  Thanks in advance.

If I remember correctly, the AV50 manual said the unit is "temperature
compensated", which tells me you should see little difference in the
amount of climbing for a given ride, whether you ride in the cool morning
or hot afternoon.  My AV50 does seem quite consistent.

If I pick up my AV50 off the living room table and hold it in my hand for
5 - 10 minutes, I do notice the altitude reading will drop 40 - 50 ft.

But you also need to figure in your own time -- both to and from the
bike shop, and doing without a wheel (yes, and tinkering).  Then there

  Hello all,

 I'm new today to this "bulletin board" system so I thought I'd ask or
some advice re: winter riding.
  This is my second season riding and, unlike last year, I wish to ride
through the winter.  (Last year I rode the "warmer" months and then hibernated
for the winter.  Needless to say, you can imagine my condition when this
spring came around).
  What would one recommend as far as proper clothing is concerned?  
  On another aside:  I recently mail-ordered a Vitus 992 frame from Colorado
Cyclist with Campi Chorus components.  Anyone have any experience with a
road bike set up similarly?

And I believe they are deluding themselves.  The modulus of elasticity
is only valid and interesting at stresses below the elastic limit, aka
the yield stress.  It is controlled by the "stiffness" of the atomic
bonds within the crystalline structure of the metal.  The "6/4" Ti alloy
contains approximately 90% Ti, 6% Al, and 4% V.  The alloy's modulus is
not going to be significantly different than that of pure Ti.

As an example for which I happen to have numbers, the modulus for cast
and wrought alloys of Al vary from from 10x10^6 psi to 11.4x10^6 psi,
while for the same span of alloys the ultimate tensile strength will
vary from 10,000 psi to 88,000 psi.

It is quite possible that the higher yield and ultimate tensile
strengths have allowed designers more freedom to fashion more efficient
spindles and tubes (e.g.  larger diameter, thinner walls), but the

The yield strength difference is quite believable.  In fact, the 6/4

1.5%Fe, 1.4%Cr, 1.2%Mo alloy has a heat treated yield of around 184,000,
for an increase of over 20%.  It even has greater elongation that 6/4,
however its modulus of elasticity (stiffness) will not be significantly
different.

   They are difficult to put back together without they special replacement
   link, which costs $2-3.  They can be put back together without the special
   link but it is tricky.  Use a Hyperglide or gold Cycoli chain tool.
   They do seem to break more often than other chains, I hate to admit.
   I've now broken 4 hyperglide chains in 3 years.  2 of these were due
   to pilot error in rejoining the chain without the special link.

Are we talking about a special 'link' or a special 'pin'?

Tom, from earlier experience with your responses it is evident that you
just can't leave a dead horse lie.  You imply that there is an advantage
to using BioPace and that we, the majority of riders, have overlooked it.
Talk about indirection.  Now I understand why that term rolls so easily

You are bending over backward to exonerate Shimano but it won't work.
If I believe you then Shimano must be stupid.  Have your choice, either
they performed "somewhat incorrect research" in the presence of
overwhelming evidence throughout the history of odd variable velocity
foot motion, or they were deceptive as Harry Phinney proposed.  If you
want me to believe that they have no control over their marketing arm,
then you are calling their management (the four brothers) incompetent.
From their track record I find they were not stupid or incompetent.
This leaves deceptive.  I am sure you can come up with a dozen
"but what if's".  I find them tiring as was your endless tirade on air
flow.

That may be one advantage of a city designed by slightly infantile emperors.
The main roads are insanely wide (for German standards), and there is a
city freeway system, some of which inexplicably fails to be blocked by
road construction crews, some of the time. Hamburg, for example, has
neither; if you have to go through Hamburg in any way you have to go
through the *center* of Hamburg, or risk getting lost in a maze of twisty
little residential streets.

This means that the average is probably lower in other cities. Bicycle
facilities in Berlin are acceptable (but not great), so bicycle speeds in
other cities may also be lower. Anyway, I can't imagine that anyone with
a commute of less than six miles each way would use a car except out of
ignorance, or a physical disability. I am also singularly unsympathetic
when people complain about traffic jams - they are not *stuck in* a traffic
jam, they *are* the traffic jam.
