I. Questions on two inexpensive helmets:
	I have been encouraging other students to get into bicycling,
and I always recommend that they buy helmets.  In an effort not
to scare people away from the idea, I name the cheapest helmets
available locally, the Rhode Gear Ultralight and some other similar
helmet (Advent Air?).  Unfortunately I've never tried one of these.
They are both Snell and Ansi approved, but I dont' know how well
they ventilate.  has anybody tried either of these all-foam helmets?

II.  Gluing tires pieces onto shoes
	As explained in my last story, this didn't work because the
epoxy wouldn't stick to the inside of the tire pieces.  Can anyone
tell me what will stick to these things, or how one could prepare
the surface to encourage adhesion?

III.  What are the disadvantages of low-profile cantilever brakes
over normal ones?  I have normal ones on my bike, but plan to
replace them next year (my new seatpost comes tomorrow, meaning
that everything will have been replaced except the BB, headset
(both have new bearings), the front derailleur and crank.  What
are Servo-Wave levers and why do they help?  Do low-profile brakes
inherently generate less power, or only if the cable is not set up
correctly?  Just what does Shimano Linear Response mean?

Any and all replies, email or posted, are welcome.

Due to crossposts having been made over the last few weeks to rec.motorcycles
in regard to road use, careless posts and replies have been made recently
to rec.motorcycles regarding non-motorcycle topics.  Subjects such as
clipless pedals and Greg Lemond in the Olympics come to mind.  Since the
motor people seem to have enough hostility toward us anyway, we might be
able to ameliorate it a bit by avoiding unintentional crossposting.

>[Try that Allsop suspension seatpost!]

My stokers, especially my regular stoker, have complained about bump
butt.  With this in mind, I went to look at a variety of solutions.

 - Sprung saddles used to be common.  I found a 40's vintage saddle
with both front and rear springs.  My stoker complained that she felt
like she was pogoing down the road (``and the red-red-robin comes a'
bob-bob-bobin' along...'').  I looked at ways that I could preload the
seat springs but eventually deided it would be hard.

 - The local Allsop dealers don't acutally stock ridable bikes with
these things.  I was lucky enough to find a Tri bike 1/2" too big
for me that I could ride.  I only had time to ride about 4 miles.  At
the start of the ride I had a lot of vertical motion with every
stroke.  By the end of the ride I had learned to pedal a way that
reduced the vertical motion, but I still think there's something
fundamentally wrong with putting a spring between you tush and the
pedals.  I considered ways to put a preload spring on the Alsop. I
think it would help.  The Allsop increases the top-tube stradle
height by 4" or so, which I found bothersome.  It's hard to adjust the
seat height (a QR is out of the question).  On the other hand, riding
over bumps seated is far more comfortable.  Pamela Blalock says an
Allsop costs about $200.

 - On a net.recommendation I checked out the Hydra-Post.  It's both a
spring and a damper.  The normal setup is that the seat doesn't move
when you pedal or ride over small stuff but when you hit big stuff the
seat ``gives'' then returns to ``home''.  Again, no dealers had ones I
could ride, but I found an MTB with one that I could ride.  I had time
only for a bit less than 4 miles, about 2 miles on trails, 2 off.  The
Hydra-Post doesn't ``give'' on small bumps, so your ass gets beat up
more than with Allsop.  On the other hand it doesn't pogo stick like
the Allsop.  The Hydra-Post externally resembles a heavy 300mm
seatpost (still probably lighter than Allsop, I don't know) so it can
be used w/ a standard QR and doesn't booger top-tube clearance.  A
Hydra-Post costs about $100.

 - I've talked w/ several folks who have Suspenders on the front of
tandems.  They don't help the stoker much but all captains have said
they like them on fast trails and for road riding.  Ibis built a
one-off prototype with Suspenders front and Offroad rear a year ago or
so.  Although this will clearly be more expensive than a new seatpost,
it seems like the ``right'' way to go.  Sorry, but I don't have any
riding impressions :-)

A friend of mine recently purchased a Centurion bike, and is doing some
re-outfitting of components.  I think it hails from 1985 or 86, as it 
came with friction shifting.  In any case, he was wondering if anyone
had any idea how the frame was spec'd.  The only decal left on the frame
says "Cr-Mo."

I ride a Cannondale ST600 with rear panniers and low riders
(probably 30-35 lbs of gear) on long tours.  At the time I bought
the bike I had little knowledge about frames other than that
cro-moly was supposedly stronger and aluminum more comfortable.  I
chose the aluminum Cannondale over the Trek 420 (I think that's
the correct model) because it was the only bike I found that was
specifically designed with touring in mind (mountain bike components,
touring geometry, cantilever brakes, etc.)  Actually, I did consider
the Trek 520 also, but wasn't sure I would really get into full
blown touring at the time, so wanted something that also seemed a
little more like a standard road bike.

Anyway, I've been extremely happy with the bike, but have often had
to listen to people's fears about the thin walled tubing of the 3.0
frame.  Has anyone out there had any personal experience to justify
the inferiority of this type of frame when compared to either cro-moly
or "thick walled" aluminum (eg Trek)?  Are there things I should be 
careful of or be on the lookout for?  I realize if the frame is damaged
it is history, but what sorts of things (short of being hit by a car)
would cause such damage?  I recently worked on my bike at a co-op
repair shop, and the supervisor warned me against putting the seat tube
(not sure this is the correct term) in the stand clamp for fear of 
fracturing the tube.  Is this justified?

Any info would be appreciated.

Two possibilities are the seat leash, a cable that allows height

I first started reading net.bicycle in 1983 back in the days when Bernard

I can even recall disputing something with Bruce Hildenbrand and challenging

There are some of them you just can't avoid.  I had an automobile
accident some 15 years ago in which the driver on the side street
came to a full stop at the yield sign, looked me full in the face,
and pulled out directly in front of me.

Eye contact is a very good sign.  It *usually* means the driver at
least sees you.  It is far from infallible.

	Well, I tought I could get away with not falling during the learning curve
period of using SPD clipless pedals. I was wrong!!! Yesterday I had my first close
call followed shortly after by my first fall.

The close call was sort of scarry because I was stopping at a red light and I did
not take my feet out of the pedals fast enough to be safe so I started falling. I
fortunately could unclip (is it the word?) before the point of no return and landed
my right foot safely on the ground.

The fall was more bizarre. I was standing still, holding onto some cart with both
feet clipped in. I got on my way when at the same time I saw a car which was on a
kind of intercept course so I decided to stop. How wrong was I!!! I started falling
down again but this time no luck. I tried to unclip until the point of no return at
which time my brain switched over to the survival mode so I put my hand forward to
soften the fall. When I hit the ground my right foot unclipped without any help. I would
assume and hope that on a more severe crash the pedals would unclip. I ended up more
surprised than hurt and I was more afraid of damaging the bike than myself in my fall.

BTW I like the pedals. They are SHIMANO M-525 SPD pedals set at the minimum tension
setting which I may increase as I get better with the pedals.

There's nothing definite about your claim, only one anecdote.  I'll add
my own anecdotes.  I've endoed in Looks and not released, and my worst
muscle tears came in a (different) crash with Looks.  They're not magic.
Whether you release depends on the circumstances of the particular
crash, and quite possibly on the reactions/reflexes of the rider.  It's
possible that my 20+ years of clip&strap use is a hindrance in emergency
situations with Looks.  I probably still try to lift and roll my foot to
release when I don't have time to think.

Last year I took up cycling althought it was mostly only on occasion that
I rode. This year, though, I'm pretty much going at it 5 or 6 days a week
and having a blast. I'm curious, though, about how much weight loss I
should expect initially. The reason I ask is because since about late
Feb. (just as soon as I could bear the cold!) I started riding 40-60
miles a week and have stayed with it. I've noticed that, although my weight
has shifted, I haven't lost an ounce. Should I expect my weight to stabilize
for a while as I gain muscle mass and lose fat? I *have* noticed that
my weight seems to have 'shifted' IE my legs are much more muscular and 
I'm getting toned in other spots. 

Does this make sense? What are some of the experiences you folks have had
as beginning cyclists?
