I'd say that this shop is liable for any and all expenses related to
getting the cup out. Problem is you'll have to sue them to recover.
 
"Frozen" doesn't mean "welded". There are a number of ways to loosen
galled or corrosion locked parts. Only an incompetant mechanic would do
what this genius did. You'll probably have to drill a few holes in the
cup to fit a spanner or some other tool, and then use heat to breeak
the bond between the parts.
 
I don't think a new frame is necessary. A good mechanic should be able to get
the cup out.

I don't know, seems to me you ought to finish with the same gears you
started with.
This seems silly to me anyway.  A pro rider like Sciandri ought to be able to
get up almost anything with a 23 or 24/39.  A 12-24 freewheel and 39/53 rings
seems pretty adequate to me in the sprinting department.

If this were really a problem, how about a 12-21 freewheel and 32/42/53
triple cranks?  That'll certainly allow some fine tuning :-)

Didn't Jeannie Longo use something like that to win the Tour de France

Careful here.  The amp-hour (AH) ratings given to gel-cells are based on current
draws of 1/10 the rating.  So a 4AH battery can supply 0.4 amps for 10 hours.
For current draws greater than 1/10, you must derate.  The curve is not linear,
but reaches ~80% at current draws near the rating.  So the 48W lamp in the
example above would only last 0.8 hours with a gel-cell.  Temperature also
effects this rating and you must again derate at temperatures below a
specified ambient.  Again, the curve is not linear, but it reaches about 80%
at very cold temperatures.  If your battery was very cold, the above 48W
lamp would last (0.8)*(0.8) = 0.64 hours.

If you keep your battery inside the house so it is at room temperature, and you
stow it in a bag on the bike, it is unlikely that the mass of the battery will
get cold during its' usage so the temperature affect can be ignored.

I bought a C-200 wireless for my wife for Christmas.
It worked fine until about a month ago, when all the segments of the LCD

it clears things up for a few seconds, but then all the segments come on

Greetings,

After 12 years of happiness with my bicycle, I have recently emerged
to shop for some new stuff.  The biggest confusion I have run across
involves the freewheels vs. cassette issue.  It seems that Campy,
Shimano and Suntour have all gone with cassette-based rear hubs.
Campy's low-end gruppo appears to still be freewheel based.  Since
Shimano and Suntour both make component sets that are too "low brow"
at the bottom end to be sold as aftermarket parts in bicycle
catalogs, I am left with some unanswered questions.  As such, I
look to the wisdom of the net.

Specifically:

	1) Do either Suntour or Shimano make any new non-cassette
	gruppos?  (Shimano 300LX, Suntour XC-LTD etc...i.e. the low
	end stuff).

	2) Is there any compatibility between manufacturers of
	cassettes?  Can I use a Shimano cassette on a Suntour 
	hub?

	3) Both of these companys seem to be making chain specifically
	designed for their "systems" (Shimano hyperglide and Suntour
	micro-drive).  Do these chains work even on the company's
	low-end stuff?  Also, are there non-propriatary alternatives.

For what it's worth, I tend to wear out chains and freewheels somewhat
frequently.  I have never "worn out" a hub or rim.  I am currently
looking at MTN bikes and at least one currently under consideration
uses Suntour XC-LTD componentry.  Since Suntour is considerably smaller
than they seem to have been 12 years ago, I'm wondering if down the
line, I won't have difficulty replacing the freewheel (oops...cassette)
that will inevitably wear out in 2 years.  Comments?

As a bike commuter, I run mine day or night.  Maybe other flashing lights

This is only one data point, but I have had bad luck with Vetta 200.
They are being dumped because there is a newer model, the Vetta 300.
I hear it's not much better.

I started having reliability problems after 6 months. Spurious readings
or none at all. I changed both the batteries. I triple-checked everything.
Then I just took it off and left it off. Oh well...

Like I say-- I'm only one data point.  Your mileage may vary.

Yeah... <sigh> but they still show some good stuff. I'm sure you got a
pretty good feel for that long single-track climb (ugh!). I rode the
course the day after the races and that climb is a bear! "The Energizer:

When it comes to the presta valve nuts, do you need two (one inside, one

one on the outside?

Reason I ask is that my MB-2 wheels had two nuts - a flatted one on the

there is a particular reason that I should avoid riding without it?

Subject: More Cateye Micro (CC-6000) Bashing--Some Observations and Solutions
Summary: Poor contact can cause speed jumps and high maximum speed.
Organization: University of Waterloo Math Faculty Computing Facility, Ontario.
Date: Wed, 12 Aug 1992 22:19:00 GMT

Well, the other day, I actually caught my Cateye Micro in the act.  I
had been having trouble getting it to register speed, and at one point
when I looked down, along with the more usual numbers one sees under
such circumstances, such as 0, and 7, I saw "143 kph".  Definitely no
relation to my cadence.  Tapping on the top of the unit, and pulling on
the bottom of the mounting bracket eventually caused it to function
once again, and later in the day it was functioning very reliably.  But
sure enough, 143kph had been registered as the maximum speed.

I think the intermittent readings on this cyclocomputer are due to poor
contact with the middle pin; the contact for this pin is on the middle
tongue of the mounting bracket; the slightly flexible one which
contains the "tooth" for holding the unit on.  It seems that the middle
pin must be the one for the wheel rotation detection circuit; the
return and the cadence detector must be the two outer ones; whenever I
have checked, cadence seems to continue working even when speed and
distance fail.

Presumably when the high speed was registered, the contact was broken
and reestablished very rapidly one or more times while a "pulse" should
have been registered by the wheel rotation detector, and one pulse was
actually read as several, and interpreted as multiple rotations.

Cleaning the contacts on the mounting seems to help somewhat.  While
the pins on the actual unit do not appear to corrode, their
corresponding contacts on the mounting bracket do corrode visibly.  I
have tried my eyeglasses defogger (since it was handy), and ordinary
rubbing alcohol, but presumably some sort of tuner cleaner should work
well.  Pulling up on the central tab of the mounting before putting the
computer unit on seems to help, too, but I realized that too much of
this could hurt, if it actually increased the upward force on the
computer so as to lift it away from its mounting.  The design problem
is, I think, that there is no force on the mounted unit holding the
contacts together.  I think probably the pins under the computer are
spring-mounted, but these could presumably work against one another,
since there are three of them.  When the speed does stop registering, a
gentle tap on the bottom of the display often suffices to fix it
again.  If not, pulling up on the middle mounting tab, or gently
squeezing them together from the top and bottom will sometimes do the
trick.  In extreme cases I stop, take the unit off, and fiddle with the
tab some more before I put it back and try again.

But this cyclocomputer owes the fact that it has survived this long to
my currently relatively low disposable income.  Fiddling with it is
getting quite annoying.

Jim,
I'm for one enjoy riding without a helmet (unless in a large, dangerous
group) and take pride in my 20 years of _safe_ riding.  I wonder about 
those who seem to revel in detailing their accidents.  Do you like to
talk about the results of poor riding or do you believe it 'wasn't
your fault'?  

I would not discourage anyone from wearing a helmet.  I think they are
a great idea if you feel better wearing one.  I just wonder why some
people feel compelled to criticize others who enjoy cycling without a
foam bucket on their heads.  It couldn't be that comfortable if
everyone takes them off as soon as the dismount (except for a few
oddballs).  Having put in over 200,000 miles in various conditions, on
various continents, I tend to put more faith in my own judgment of
when a helmet is appropriate than others, like Les Earnst, who
ride relatively little yet nevertheless seem to feel they know what is 
best for me.

I have a 1989 Santana Team racing tandem bicycle, in perfect condition, for
sale.

This is probably the most beautiful bicycle ever made. The fillet brazing is
absolutely perfect; each tube seems to flow into the next. And the paint
(eight coats of gold-flecked pearlescent white Imron) is astonishing to look
at. It also has violet water-bottle cages,  violet and white zebra-striped
saddle covers and gold handlebar tape.

The frame is Columbus tandem CrMo (not Nivacrom). It is equipped entirely
with 8-speed Dura-Ace components except the pedals (Campagnolo C-Record with
alloy clips), the rear seatpost (SunTour XC) and the brakes (Shimano Deore
XT). The rear saddle is a woman's racing Turbo.

The frame is 53 cm front and 50 cm rear, but these sizes correspond to
somewhat larger single bikes.

This bicycle sells new for $4495. I am asking $2995. It is being offered for
sale because of a romance gone tragic. The bicycle currently resides in
southern Vermont.

"Load up, load up, load up, ruuubber bullets!"

No, that's not what I had in mind, though 10 CC sounds like a plausible
size for a equivalent-power engine, should I need to replace my current
pasta-burner mechanism.

I've been having an E-mail conversation with another netter and on the
subject of valves I realized that I've never heard an American mention
any other than Presta and Schrader valves. Is this a reflection of the
market or do you (like we do) have a third kind that you don't want to
talk about?

The dreaded secret must be forced out into the light. Despite over a
century of product development in the field of cycling, the majority of
Swedes still in their hearts believe that a REAL (tm) bike valve must
always contain a small piece of rubber tubing and anything that does
not is regarded with extreme suspicion.

Does this ring a bell with anybody outside Scandinavia?

The central part of this valve mechanism (both literally and
figuratively) is a small, hollow, metallic stem, about the same
diameter as a Presta valve. It's open at the outer end but at the inner
end the opening is in the sidewall. A short (1 cm / 0.5 in) piece of
rubber tubing over the inner end allows air to pass in one direction
but not the other. The stem is inserted in something that vaguely
resembles a Schrader valve and is held in place by a special nut.

The losses when inflating one of these tubes are great, and I doubt
that anybody could ever pump one to more than 40 - 50 psi. Which is
just as good, since the Swede in the street disapproves of hard bike
tires too and refuses to believe that a skimpy bike wheel can safely
harness more pressure than a heavy car tire.
