I concur that salt is a problem, but I find the biggest problem is that
water washes the chain dry in short order -- a chain is adequately
lubed when it's wet, but when it dries  it needs relubing.  Leaving it
in the rain in the morning can leave me with a squeaky chain in the
afternoon.  I suspect that lubing the dirty chain is still better for
it than riding it home dry.  It sounds wretched when it's dry!  I hope
by this fall that I will have a chain case on my 5-speed commuter.

Water also washes the lube off of cable runs and brake and derailleur
pivots, and sometimes leaves them rusty.  Periodic lubrication is the
only solution I've found.  Once a week seems like it's enough, once a
month doesn't.

Riding in the rain also washes junk in to the bearings.  I've never
figured out exactly what combination of riding in the wet and parking
outdoors causes the most infusion, but hubs with poor seals seem to
pick up a lot of crap in a month.  Good labrynth or rubber seals seem
to do the trick.  Fenders help keep junk out of the headset lower race.
So does a piece of inner tube, next time you have the headset apart.

Brake pads sometimes wear quickly in the rain.  Cantilevers can wear
and tuck under the rim, losing the brakes or jamming the wheel;
centerpulls can wear and ride up, destroying the tire casing and
causing a sudden flat, sometimes while braking.

The stem binder bolt and the place where the aluminum stem touches in
the steel steer tube need to be lubricated, or they can sieze.  This is
true in general, but a worse problem when the bike is spending time in
the wet.

If you have a porous saddle, it saddle should be protected when the
bike is parked, or you will get a wet posterior from it.  Leather
should be protected of it's own right.

I just returned from Aspen, Colorado area (elevation 8000ft) where I spent the
past 10 weeks.

I just did the local club's weekly 15K time trial.  WOW!  Without using aero
bars, I managed to do it at an average of 38km/h even though it was quite
windy.  The funniest thing is that my lungs were not hurting at all.  During
the trial, I wasn't breathing all that hard, either.  I couldn't go faster
because my legs were hurting.  I'm sure my body is very efficient at destroying
excess red blood cells, though.

(I know, I know, 38km/h is not that fast, but it's not bad for a geek comme 
moi!)

Mike, your experience matches mine exactly.  Upon advice of the net I 
tried several Sedis chains and I found they didn't shift nearly as well 
as an HG-90 hyperglide chain.

They are difficult to put back together without they special replacement
link, which costs $2-3.  They can be put back together without the special
link but it is tricky.  Use a Hyperglide or gold Cycoli chain tool.
They do seem to break more often than other chains, I hate to admit.
I've now broken 4 hyperglide chains in 3 years.  2 of these were due
to pilot error in rejoining the chain without the special link.

Overall I think the improved shifting makes the HG chain worthwhile,
in spite of the increased failure rate.

    My understanding is that these are WIDTHS, not extensions. The choice
is a tradeoff between aero advantage and comfort. The bigger your upper
body is, the more width you need for a comfortable position. It also 
depends on your intended use. I have a large (44 inch chest) upper body,
but I use the narrowest Profile clip-ons I could get. I am using them 
just for time trials, and all I care about is being comfortable enough
to use them for 1 hour (preferrably less ;} at a time. If you want to
go touring on them for 5 or 6 hours a day (or more) then you may want
more width. 


                Just my opinion!

JUst thought I'd put my $.02 worth in about this world championshi race...	
If the TDF was any indicator of who is likely to prosper in the race, I'd	
have to go with Chiappucci.  While there are no climbs comparable to the 
most severe in the tour, they are still enough to make Chiappa a threat.	
I dunno if hampsten is in the race, or not, but he could do well, though it 
seems a little long for him.  ONe has always to watch Gianni Bugno...did
you see how fluid he is?  When he was hammered on the stage to Sestrieres,
he was barely bobbing in the saddle...Not to mention that his time-trailing	
is, IMHO, about as close to Indu's as anybody's.  If he weren't the 	
defending champ, he'd be my bet. I'd be a fool to write him off, tho',	
I mean, he is THE WORLD CHAMPION, and one doesn't get that by mistake.Add
to that a victory (commanding) in the giro a couple yrs back...well, you never
know.  His big problem will be that everyone will be marking him closely.	
Same problem for Indu - he just embarrassed everybody at the TDF, and the whole
peloton will probably have a good eye out for him, as well.
One has to wonder about the riders like Mottet and Chioccioli, Breukink, et al.
Guys like these are good enough to win national tours, but come up just short
because of bad luck, etc.  I like Breukink, because he can climb very well, 
and is one of the best TT riders in the peloton.  Let us not forget
Chioccioli's stellar performances in the Giro, either.  Mottet is still 
looking for his big break, and he might have a go at the wc.
And now, the obligatory words about Greg LeMond...I'm not one of the folks who
thinks he's all washed up, but I do think that his days as one of the premier
climbers are past.  We all know that he can still tt fairly well, about in the 
same league as Breukink (or even Bugno), but the Benidorm course might prove a
bit to hilly for greg the great.  BUT, he might also be out to vindicate his
TDF performances, so we never know.  I'd place him 15th or so.
I'd place guys like lejarretta, and Leblanc in the top 10.

I don't know what was hidden.  My point is that those who believe that
the pedal stroke wastes work because the lever is zero at the top of the
stroke and varies sinusoidally through one rotation are unaware that
just pushing on a pedal is not work but that moving a pedal is.  Hence
my example of standing around with foot on bar rail.

What the chain does is of little consequence.  Although the foot may be
going in circles the ratio between foot and bike motion varies during
rotation.  Because the bike and rider travel at relatively constant
speed (having much inertia), the foot and leg move at a jerky rate.
It is this uneven rate and its acceleration that makes the whole concept
fall apart while gaining no advantage in power.

I may be assuming too much but I think that those who follow this thread
are aware of the relationship between force distance and time with respect
to power and that often the connection is not made because it is not
obvious.  An example is usually sufficient to jog the mind.  I don't see
this as indirection.

How about a tax on birth certificates? We could tax anyone that has children
because it is children that use the schools. Children also grow up to
be adults that have even more children and the population boom continues.

Jobst, I sent you email last week about this, but it bounced and I

What's the story with your book.  Even non-net bicyle mechanics
recommend your book, so I went to my local bookstore to order it.
They kept my deposit for a month and then called me back.  The
publishers told them that the book would not be available until
January.  What's the story?  Is it out of print and awaiting a press
run or is it just out of season, sitting in a warehouse?

Try the *really* soft handlebar grips made for cruiser bikes.  I use 
these on my AT-4 pros on my about town bike and they provide plenty
of cushioning for the forearms.  If you want even cushier you can
wrap them with Sampson Fat Wrap.

I find the aero position of the AT-4 pro one of the most comfortable
positions I've ever found on a bicycle.  When first recovering from
a broken back the bike with AT-4's was the only one I could ride

Your shifters are of a different vintage than the original poster.  Campi
used to use only metal friction elemets.  They worked well but required
occasional cleaning and oiling/greasing.  Later Campi started using a
plastic friction element.  The plastic element did not provide enough
resistance for the formitable spring on Campi's rear deraileurs.  The
shifters were so bad that they sliped even on stiff frames when the screws
were torqued down very tight.  Even the most die-hard Campi fans started
using other shifters.  With the C record groupo Campi intrduced the
retro-friction shifters that were strong enough to not slip yet were still
easy to move.  The idea seems to come from a shifter from Stronglight that
used the same principal.

My guess about the original poster's problem is that either some parts are
missing from the shifter or it is assembled incorrectly.
