Subject: Helmet gift advice wanted
Date: 17 Dec 92 13:12:51 EST

My new son-in-law uses a bicycle for transportation in Lincoln, Nebraska.
He's had at least one altercation with a car and they've decided he wants
a helmet.

What do I want to know before buying one for him?

I get the idea from articles still in the spool here that head size
is not enough, head shape is an issue too.  Do we have to take him
to try helmets on?

An earlier time when I was reading rec.bicycles, I picked up that the
foam is only good for one crash.  Are there helmets that have replacable
liners?  Are hard shells any benefit at bicycle energies?  Is the pure
foam that will be broken into pieces after the first crash a better
way to go?

What questions should I be asking?

(I will try to catch any responses that are posted here, but it would
be a kindness if you would mail to dlh@dlhpfm.uucp - I will post a
report.)

Hi, I would like to get a few more sets of toe-clip covers.  I have
one set now.  For those who have not heard of these: toe-clip covers
are nylon covers which fit over the toe-clips.  They are held in place by
wrapping round the toe-strap.  They make a pretty good wind barrier for
cold weather riding (their design intent).  They can also be treated and
be helpful keeping shoes dry while riding in the rain.  For those who
have not heard of toe-clips and toe-straps: hit 'n' now.

I use them for wet and cold weather riding.  They are
wearing out.  My wife needs a set too.  They are
not available in stores anymore.

Would anybody like to sell me a good condition pair?

Or, does anyone knows of a place where I could purchase them
new?

NNTP-Posting-Host: underprize.think.com

I currently have a Univega touring bike from the mid-80's, and I'm
trying to decide whether to upgrade the componentry or spring for a new
bike.  I was looking at the upgrade (index shifting, wider gears, 175 mm
cranks), but I've been pretty close to talked out of it because it looks
like $400 total and because my current bike is fairly heavy.  A local
bike shop has a very nice looking bike (Specialized Allez Sport '92) for
$569; I'm trying to decide whether to go for it.  The componentry is
Shimano RX100 (supposedly their low end racing line).  Questions:

1)  How's the price?  I'm trying to knock it down some on general
principles, but no luck so far.

2)  How's the frame, particularly if anyone's familiar with the bigger
sizes (61 cm in particular)?  The floor model was 48 cm, and it only had
an oversize downtube; they claim the bigger models have all oversized
tubing.  I'm about 6'4" (34-36 inseam) and weigh about 230; is this
frame reasonably stiff?

3)  General impressions, if anyone's familiar with it?

Email to me is fine; I'll be happy to forward responses to interested
individuals or to the net.

My fourteen year old daughter is yearning tearfully after an all terrain
vehicle to replace her trustyPeugot 12 speed of fine years back. All her
friends have this quasi mountain bikes and so - naturally - she wants one
also.

I ride a 1976 Mondia, all campagnolo gear, and I used to work at Alfa
Romeo in Italy. I maintain everything from plumbing through computer
equipment so I was wondering whether it was possible to buy a bike direct
from the manufacturer, in an unassembled state, and set it up myself. I
rebuilt most of my beloved mondia and I see no problem.

The reason is that the price of these lovely machines is high. I cannot
bear to buy her a department store horror (although my wife thinks they
are just dandy :-< ), they are just too awful. We have looked around and
she likes the GT Timberline, perhaps the Talera. Either way we are at
$400 or more.

She wants rapid fire shifters, or the new '93 things. No biospace chain
wheel (my requirement) - 7 free-wheel, 3 chain wheels and so on.

Are there mail order outlets for unassembled bikes - like computers - at
delightful discounts? Or can one approach the manufacturers directly? Are
there outlets where one can purchase the individual components, then
assemble them at home?

All help will be greatly appreciated.

Thanks - Lawrence

I'm looking for used stuff to build up prototype frames (I build
road, track and TT frames as a hobby) As it is, if I get a frame
ready to be built-up, I have to switch components off something
else. It's not too much of a hassle with the track bikes, but it's
a PITA on the others. Obviously, I don't need Dura-ace or Surpebe
Pro, but I could use Ultegra, 105, Sante', RX100, Blaze, etc.,
or a combination of any of the above (as well as Suguno or SR) because
I'm more concerned with checking out the frame than I am with
index shifting or the latest hoop-te-do gee-gaw. So far, I've
had no offers, but I just know someone out there has a garage full
of old components they want to get rid of for next to nothing...
<grin> Actually, I'm willing to pay a fair price and shipping
for groups and pieces. They will stay in the shop and NOT resold
as I just sell frames (every second blue moon) when I have
time to build them, I'm not in the bike selling business.
Keep the forked end down and thanks for the query,

I was wanting to get some advice on mountain bikes that are in the $300 to
$600 range.  What would be the recommended component set for this
price range? 

I along with three other people are looking to make a group purchase, with 
hopes of getting a better price.  We are not picky about where the
dealer is because we have access to Nashville, Birmingham, and Huntsville
bike shops for test riding.

Any recommendations and advice is greatly appreciated

These colored coatings are not hard anodized and do not have a
substantial effect on the material except to protect it against
abrasion and corrosion.  Unfortunately, the dyes used in these
processes often fade over the long run when exposed to sunlight.

That doesn't mean you shouldn't look for cracks unless you are a
lightweight rider.  Most bicycles, whether steel or other material,
are built as light as reasonably possible (and lighter than that).
From my experience, all high performance bikes run near the fatigue
limit if ridden hard for a long time.  All my steel Italian frames
developed cracks and the ones since then have died in crashes.

Seat posts get sheer loading where they come out of the seat tube. Carbon

You're talking about the wrong kind of kevlar tires...  Kevlar beads will
make no difference in the "flattability" (nice word) of your tires.  The
questions about kevlar tires here are concerning kevlar-belted tires, where
there's kevlar below the tread of the tire so as to try and keep glass and
thorns, etc. from getting to the tube.

Snakebites result only from running too little pressure.  If you were getting
snakebites at 70 psi with mountain bike tires, you must have been slamming
into curbs (or maybe hitting fairly big, sharp-edged rocks) at 30 mph!  I
have never pinch-flatted with 45 or more pounds in my tires, and I weigh
165 lbs.

Another thing, I agree the Ritchey WCS tires are flexible, they're also about
the least durable tires I've ever ridden on.  They cut VERY easily (the casing
is just plain weak).  I did one 45-mile race on them and ended up ripping
half the rubber off the rear tire (on hard packed climbs I was able to 
generate enough torque to tear the knobs off--that's not a very durable tire!)
and got a 1 inch cut in the front tire when I hit a small sharp rock 
(that wouldn't happen with Conti's).  So, while the tires have really good
traction and are absurdly light, their lifespan (maybe 100-150 miles for me)
is WAY too short for a $40 tire.

But, if they work for you (which they seem to), then go ahead and keep using
them.  But just realize the decreased frequency of flats isn't related to
the type of bead on your tires.

Greetings, fellow bikists.

I'd like opinions regarding the purchase of a $500-600 MTB for my wife, who
is 4'11" and 92 pounds soaking wet.  She could probably ride a 15" frame,
but it's just a bit larger than it should be.  I've found some 13" and 14" 
frames that are reasonably inexpensive (and heavy), but have yet to find
one that is outfitted reasonably well, fits properly, and is reasonably
light.

Intended use is for light to moderate off-road riding and some road
riding for exercise (not distance rides, just 30-60 minutes to work out).
If anyone (especially you women riders) has any experiences with moderately
priced ($500-600) MTBs for small people, please send email.  I'll summarize.

I like the Aspins a lot.  I weigh 180 lbs and selected 32 hole Aspins
for my competition wheels.  They were built by a friend in 1984 and
are still running strong, although they haven't seen a lot of use in
the past 3 years.  They have needed some periodic "tweaking", moreso
than my 36 hole GP4s (which seem to need almost none, and are ridden a
lot more), but have not shown any signs of failure.  I seem to
remember them weighing in the 330-360 g/rim range but it was long ago
that I knew the number- for myself, I wouldn't trust anything lighter.
As is I definitely notice a difference between the Aspin wheelset and
the GP4s, the lighter wheels accelerate better and give me about 1
gear when climbing (maybe due to the adrenaline when competing!).  I
think I paid $25-$30 in '84, so $10 seems great to me.  Grab em!

Isn't a helmet that fits properly is more likely to protect you in
the event of an accident? This might be preferable to one you can
replace cheaply.
If the hat fits...

I don't know that much about the Mavic parts although I am also interested
in them.  I do know that they tend to be fairly heavy because Mavic is
more interested in durability than light weight.  BTW the next issue of Velo
-News is supposed to have a complete test of the new mavic and Campy components.That should be pretty good, I don't think it will be out until mid-January
though.
