Recently I bought a used bike, which generally seems to be in excellent
condition (3 yrs old, not many miles.)  Unfortunately, the moron who put 
the cranks onto the BB last seems to have gorilla'd them on with a big
hammer, to the point that the tapers on the cranks have deformed somewhat.
Attempts on my part to remove the cranks were only semi-successful: the left
one came off, the right one did not.  I used a Park crankarm remover, and
made sure it was screwed in all the way, yet succeeded only in stripping the
threads on the crank (there are still threads left: the socket for the
crank bolt is deeper than my remover.)

HELP!  Does anyone have any experience in dealing with this problem?
Email and post are both fine.
Thanks in advance.

Why not print out a bunch of the "my helmet saved my life" and
"if only he/she had been wearing a helmet" stories for her to read?

Or tell her what my husband told me (paraphrase):

"People who wear makeup when they are exercising look like boneheads."

(I finally agreed with him, and don't wear it anymore, even when I'm
not exercising  :-)

Tell her that you love her and having her brains intact is more important
than her makeup or hair.  Tell her how cool it is to have major "helmet
head" hair after a ride.  Lay down the law and tell her you won't ride
with her unless she wears it.

As for her slow speed, you could tell her what my husband told 
me (paraphrase):

"Hurry UP!  Stop riding like a baby!  Let's GO!  We're going to be
out here ALL DAY!  Stop being such a chickensh**!"

You could tell her that, but it probably won't help (didn't help 
with me...I just yell back "Stop YELLING at me!  But we always have
a great time anyway.  :-) )

Seriously, why is she slow?  I go slower because we go mountain biking and
I'm scared to haul a** down the mountain.  If she's scared, experience will
help.  If she's not in good shape, working out will help.

Maybe get a tandem?

Hmmm... reminds me of the first time I rode my brand-new Stumpjumper.  I
was tired of getting left in the dust, decided to go for it and catch up.
I hit a rock, flew over the handlebars, got some great road rash, think
I cracked a rib, and almost passed out.  But I wasn't seriously hurt --
I had my Bell helmet on!

Maybe there's a lesson in that for both of you.  :-)

The lab units are hysterious brakes (the better ones).  They are great but
one that handles 400W continously is about $700 Cdn.  They are very constant
loads (repeatable to < 1% for 1,000,000+++ revolutions).  Right now I am
toying with an alternater as a load.
  What is your system like?  ie max power (peak, sustained) ...
Some of the ones that I have used had digital interfaces and as soon as I 
saw the power increment buttons (that went in 2W steps) I knew that I was
using a toy.  The newer units which the Kin. dept has (like that digital
one) can only go upto 250W or so.  Simple yes.  Cheap no.
  Of course one of the interesting things is that the data is repeatable
and seems to be mostly (if not entirely) independant of saddle position 
and/or pedaling technique.  Of course when doing VO2 max tests you can not
stand and stomp because of the ECG electrodes over your chest, neck ...
Of course you will also get different results depending upon how quickly 
you ramp the power up.

Suggestion: when riding across the Dumbarton Bridge between
Fremont and Palo Alto, ride north to Marsh road instead of going
straight down University. This can increase your longevity.

My wife and I decided it would be fun to ride our tandem across
the Dumbarton bridge to the Crafts Faire in Palo Alto on 8/23/92.
We rode directly down University through East Palo Alto, a well
known distressed neighborhood. As we waited at a light, everything
seemed cool, with people hanging out, and a young couple waiting
for the light at the cross-walk. Suddenly, on the opposite corner
came the sound " BANG-BANG-BANG-BANG-BANG-BANG!!!!". As it registered
in my mind that this was hand-gun fire at close range, three men
came running out of a store about 50 yards away and ran off down
the street, fortunately NOT in the direction WE were going. I looked
at the young father standing next to me and said "wow, that was for real!",
and he replied, "Yeah, its scary around here". Not having gotten a clear look
at the perpetrators, we decided to ride on, smelling the gunpowder as
we passed opposite the scene. Numerous people were out checking out
what had happened, and several voiced objections to our presence.
All in all, we were glad to cross into yuppieville (oops, I mean
Palo Alto), where the BMWs line the streets and the bike paths
go both ways.

On the way back, we took the following detour, which added about 4 miles:

From down-town Palo-Alto, we rode north on Middlefield about 2 miles
to Marsh Road, where we turned right (east) and rode till we crossed
Highway 101. After 101, we turned right onto the expressway that
runs along the shore and leads directly to the Dumbarton Bridge.
A bicycle path runs along the east side of the expressway, and we
will probably use that the next time we go, since the shoulder
of the main road is very narrow and bumpy. This detour avoids
the war zone on University and on Willow roads.

Other than the excitement, we had a great ride, and enjoyed the
bridge crossing.

I have done this trip many times and highly recommend it.
Here are a few pointers:

1. Pick up one of the many books describing the route.  It
   is not as simple as simply staying on Route 1 (which in 
   some places is both illegal and unsafe).

2. Ride North to South.  A comfortable unsagged pace is eight days.
   Subtract a few days if you want to push hard; add a day or two
   if you typically have mechanical difficulties.  The ride can be
   done much faster of course by those trying to set records rather
   than doing it as recreation.

3. The only "unusual hazard" I remember was between LA and San Diego.
   The route runs through the Pendleton Marine base.  There are 
   "Tank Crossing" warning signs on this road.  Also, I was firmly
   advised by the sentry at the entrance not to leave the prescribed
   route as did some previous cyclists who took a wrong turn and rode
   too close to an artillery practice range.

4. This can be a much hotter ride than you might expect if you are
   not familiar with California weather patterns.  October is 
   usually the clearest month along the coast.

5. The biggest hassle is that on some part of this trip I encounter
   a road oiling crew that is not practical to detour around.  These
   workers make no provision for bicyclists -- typically one is 
   forced into one very narrow lane of sometimes high speed traffic.

I really must improve my tongue-in-cheek style.  In parts of the story
I was trying to satirize the impatience of a motorist who has to wait a
little while behind bicyclists.  Of course, I not infrequently have to
wait behind tractors, and horse-drawn vehicles, but the fact this was a
pickup truck seemed to make it worth remarking on.

You are right, in general.

If one of the following had not been true, I would not have passed:
a) the road in question is EXTREMELY devoid of motor traffic
b) drivers around here are not usually dangerous or even impolite
c) farm equipment is rarely towed on a road for more than two miles
d) I have a rear-view mirror on my glasses
e) the truck's speed was slow enough that it would take a long time
   to catch up again (neither the downhill nor the uphill were extreme)

Probably it was not nice of me to pass the truck merely to prove that
it was holding me up.

You must be very careful here because the drag induced by an airfoil
(fan blade) is proportional to the square of its velocity.  So the 
power required to turn the fan should be proportional to the cube of
the rpm, but there may be other factors involved as well.

I have a Computrainer which measures (or at least claims to measure)
both instantaneous power and total work done over a period of time.
There is a PC interface, so it may not be too hard to get ahold of the
data in real time and do your own processing.  Since the resistance is
produced electromagnetically by varying the current in a loop of wire,
I would tend to believe the numbers, but you could double-check
against your power hub.

A guess I'm a bit surprised that similar things are not in common use
in labs since they should be simple and inexpensive to construct.

There was a tremendous response to my original posting. So much that I didn't
even have a chance to thank all of you individually. Thus, I do it now:

Dear Respondents: I gratefully thank all of your for you kind responses.

SUMMARY:

#1 Re wife not wearing a helmet: almost all respondents (with a couple of
exceptions) were on my side and suggested various means of making her wear
the helmet such as "tell her you love her" or "fake an accident" or "show her
some news reports on accidents" or "tell her she looks beautiful in the
helmet" or "buy a sexy helmet" (she got one: Bell Quest) or "refuse to ride
with her" or "get a new wife".

#2 Re wife not maintaining the bike: almost all respondents suggested that I
do it. The best response was: "Would you trust her doing the maintanance
anyway? Don't you want her to be {\it safe\/}?" OK guys (and some gals), you
convinced me; from now on (as in the past, and just like with her car etc.)
I'll do the tires and the chains etc. (Question to the ladies: does {\it any
of you} ever maintain your own bike? (For some reason, none of my female
family members (mother, wife, daugther, etc.) were ever even able to replace
a light bulb!))

#3 Re wife riding slower than I: this is a universal problem. Many suggested
that we buy a tandem (not practical) or that I work out before and/or after
our ride (that's what I've been doing) or that I carry a weight on my bike
or, and this is the GRAND PRIZE WINNER, that I should "pedal with one leg
only".  Wow!!! I luv the suggestion, and I'll do it.

Thanks again. Take care...Paul

I read that symptoms include the "numb" hand syndrome that some riders
experience. 
A recent article in Bicycle Magazine stated that correct handle bar width
had alot to
do with this problem for bike riders.  The idea is to keep the wrists as

Don't use loctite, it won't help. As in my previous post on this issue,
the nylon bushing is worn out. This causes the retention screw to tighten
against the shifter lever itself instead of the retaining washers. That's
why it keeps coming loose. All he needs to do is replace the bushing.

Are his mounting bosses clamp-on, not brazed-on?

I had this problem on similar vintage Campy shifters which were clamped
on;  the boss was actually rotating in its mount.  Sometimes it would
catch for a while, but later would work loose.

If your friend can find some new clamp-on bosses, or is willing to
have new ones brazed on, that is what I would recommend.  Someone
really handy might be able to persuade the bosses to stop rotating in
their mounts by some sort of welding/soldering process.

Luckily for me, Campag tried for a short while a strange gimmick that
was supposed to hold a chain from a five-speed setup nicely on a frame
spaced for a six-speed hub when the wheel was removed.  The upshot of
this was that my favourite bicycle store had compatible clamp-on Campag
bosses that I was able to buy, even if they did have the peculiar
although innocuous design feature of not having a stop for the rear
lever although they had one for the front.

I make sure I do not over-tighten these new ones, since that might
loosen the new bosses, and I have not had that particular problem
since installing them.

Of course, if your friend already has brazed-on bosses, I am perplexed
and my advice is incorrect and should be ignored.
