Date: 6 Oct 92 08:20:13 EDT
Organization: American Radio Relay League

     I saw a head-mounted light at Eastern Mountain Sports 
(Hartford, CT) store last weekend. It held two AA batteries 
right behind the light and had elastic straps that loop 
around and over one's head. I think the elastic was stretchy 
enough to go over a helmet. Unfortunately, the thing cost 
$28.
     EMS also had a solution better suited to my stingy 
nature. It is a thing called Jakstrap ($5.50, from Oregon I 
believe): an adjustable (velcro closure) elastic band that 
fits around one's head. Sewn to the band are three smaller 
elastic bands sized to hold a AA flashlight. The light can 
be mounted at various angles by using combinations of the 
small bands. The thing appears very well made, and it's 
washable.
     I've used the setup at night and it works very well 
with the band on my head under my helmet. It's like carrying 
a heavy pencil over my ear. By turning my head I can easily 
point the light wherever needed: roadway, computer, 
roadside, windshield of approaching motor vehicle, etc. I do 
find my flashlight is a little dim: It's only useful on the 
roadway about 30 ft in front of the bike. A better 
flashlight, bulb and/or connections to another battery on 
the bike may be in order.

AAAAAAAARRRRRRRRRGGGGGGGGHHHHHHHHHHH!!!!!!!!!!!!!!!!

The color of a helmet affects the absorption and emission of radiant energy
*at the surface of the helmet*.  Nowhere else.  Now, between the surface of
the helmet and the surface of your head is an inch to an inch and a half of
expanded polystyrene foam.  How much heat do you think the foam conducts? 
Do any of you guys seriously think the absorption and emission at the
helmet surface can possibly make *any* detectable difference to the
wearer's head???

The whole issue of helmets making your head hot is bogus anyway, in my
opinion.  There have been tests measuring the temperature of a rider's
scalp with and without a helmet, and finding no significant difference.

some awful noises and poor performance.  Luckily I never experienced anything
more serious.

	Well I have replaced the old Aris with a Shimano Dura Ace 7 speed
freewheel.  I have read that these freewheels have good seals and also
provide lubrication ports.  With the Maillard, for maintanence I would
soak the freewheel in degreaser, then fill with Phil Wood Tenacious Oil
(by dripping oil into the four holes on the outside of the freewheel).
What's the best procedure for the Dura-Ace freewheel?  Can I basically 
follow the same technique?  How often does this need to be done?

From what I've read, I'm convinced that Bianchi makes excellent
mountain bikes.  When I upgrade in a year or two, I'll be looking
very carefully at the Bianchi Peregrine (also Bridgestone MB-3
and Specialized Stumpjumper).  The problem is that I've been unable
to locate a dealer in Massachusetts or New Hampshire which stocks
Bianchi MTBs.

Bianchi seems to suffer from two problems in the MTB market: (1) Their
marketing is low key and not competitive; (2) Their MTB products
remain in the shadow of their road and hybrid bikes, which have
excellent reputation.

If anyone owns a Bianchi MTB (especially the Peregrine), I'd love to
hear some comments.  Also, if anyonw knows of Bianchi MTB dealer
within a 100 miles of Boston, I'd like to hear about it.

Finally, I'd like to throw in my feelings on oversized tubing, esp.
headsets and forks: I think they're primarily a marketing gimmick.
It has also been suggested that they're spec'd in an attempt to
control risk and reduce liability, and I find that this is plausible
as well.  Giant and Trek make good bikes, but they cater to high
volume sales and are more prone to write up specs with high marketing
appeal.   Plus, I think the Bianchi and Bridgestone bikes just look
great with their light weight lines.

I don't know about this problem, butm i've stayed away from the STi shifters
because they're so complicated.  Why don't you just temporarily put
on a down tube shifter.   Any old one will do since it's friction.  Oh, well
you'll need a brake lever  too.  If the shop you're dealing with cares
about their customers they should let you borrow these things.  You should
be able to use the same brake cable.  The extra slack on the shift cable
can just be wrapped around the seat tube.   Most shops have old stuff
lying around so it shouldn't be a problem.  If they still don't like it, tell
them your situation and that if your friend breaks anything of course he'll
buy it.

I never understood why anyone would have STI for the chainrings anyway.

I am not an engineer, folks, but perhaps some of you will 
comment. 
You've read about side-by-sides before, but this might be
new.
  
   I propose that two totally independent bicycles could be made
so that they can be linked together, with certain bracket or clamp
members built or desiged in.

    Why bother?

    For fun.  After riding to work all week, my wife and infant 
daughter go to the park for a gentle ride on the nice, wide paved
bike paths.  The two bikes clamp together, the basket or seat in
the middle (or one side) holds the child and a backpack or two with
snacks.  We can all talk without rearview mirrors or radio headsets.
One can pedal while the other relaxes.  When both pedal, they choose
their own gearing.  At the end of the day, we are back to two, 
independent bikes.
   
   I'd really like to see this done with two recumbents.

   Why else?

    If you can sell me a cyle or recumbent which can be attached to
another, I'll buy TWO, not just one.  What *I* get is THREE. Two
independent units, and one tandem.  The sales department sells twice
as many units, and the customer is 33% happier.

    OK. Then there are all you na sayers.
    1) "It can't be built stong enough."  
      Come on you guys.  With the materials and physics available
      to you today, is this really true?

    2) "its too wide"
       Remember, with the turn of a few wingnuts, snap of a few clamps
       or other such clever devices, you're right back to two wheelers
       if the road is too narrow.  Where the path is sufficiently wide
       or the traffic sufficiently light, go back to tandem.
    
    3) "The steering won't work".  You mean a few linkages can't be
       designed to do this easily and simply?

    I am inclined to agree that for you power riders or off-the-road
    people, this might not be an attractive item.  But it is to me,
    and I think there are many other people who would be attracted to
    this.  I realize I have oversimplified the problem from an
    engineering standpoint, but I also don't believe it is anywhere
    near as impractical or unmarketable as I have been told.  You
    people work on bikes-is this really such a foolish desire, or
    could some clever, innovative person really go-to-town on an
    idea like this and DO something with it?  I'm sure this isn't
    an original notion-if so, is it worth reexamining?

My freewheel's only vices are that it occasionally smokes and makes rude

I have never done it with two chainwhips, although I would imagine that
it would depend on the person wielding the chains.  Maybe we could start
a thread on how adept females are with chain whips.  But that would

But seriously, a freewheel vice is a little device that can be used 
to grasp a freewheel by means of a number of adjustable pegs.  The pegs
engage the gears and then the whole unit can be held in a bench vice.
You are then free to do whatever you will with the freewheel, as it
is firmly held in place.  I have never seen one in the popular mail
order catalogs, either, but surely one of the places that specializes
in more tools would have them available.  If it is not advertised in
a catalog or magazine ad, I would inquire over the phone.

I broke a dropout like this about ten years ago, when I was much stronger.

The bike was a Windsor Competition, a Mexican bike that is/was a copy of
an Italian racer.  It came with Columbus DB tubing and Suntour forged
dropouts.

I was pulling a "Bugger" (trailer) on a week-long tour through SW Wisconsin.
I refused to walk hills and my low gear was about a 49.  So I "creaked and
groaned" up the hills.  At the end of the ride, I noticed the that the
dropout had sheared where it was brazed to the chainstay.  I was showing this
to a bike mechanic and he then pointed out that my seat tube was cracked
almost half way around!  The flex of the seat tube was stopped right where
the seat post ended.  (I did have a long seat post with much of it in the
seat tube.)

My pre-greaseguard XC-Pro pedals work very well with
cleats.  I usually use the same shoes on and off road and
have not had any trouble with these pedals.  The pedals are
from just before greaseguard XC-Pro pedals came out -- the
rest of the drivetrain had greaseguard already.

To be sure, take your shoes to a good shop.  I'm sure they
