First, get the FAQ and read Pete's winter cycling tips.

Second, things work better if you can find a good gear and stick to it.
In my experience the rear parallelogram freezes first, so sometimes you
can use the front shifter to ride as a 2-speed or 3-speed.  Eventually
things freeze up enough you're on a one-speed, and finally the muck in
the freewheel gets packed up enough that you're left skipping about.

What's best is an n-speed hub with a fixed-length chain.  The single
cog in back is completely clear on one side and has only the wheel on
the other.  Further, the chain exerts a lot of force if it tries to
ride up on the snow.

>[How about a boot for the rear's parallogram?]

I never tried when I lived in snow country, but I did for rain: pull
the derailleur from the frame and take off the pull wire.  Slide over a
length of fat tire inner tube.  Use small-tire inner tube rubber bands
to hold it tight.  The boot will wear out eventually but works in the
meanwhile.  I used to slide a WD-40 spritzer under the boot and spray
just a bit monthly.  I don't know how much that contributed to the
demise of the rubber.  When the boot finally fell apart the
parallelogram looked clean.  I did sometimes have problems with the
rubber boot hanging up and keeping the derailleur from the smallest
cog.  I think a fatter tube (I was using 1.5") would solve the problem.
For reasons unknown to me, I haven't put boots on any of my bikes
recently.

BTW, the SunTour Sealed Tech solved the exposed parallelogram problems.
It was a clever design that was killed by a weak implementation.  I got
mine for the price of reassembling it and it served me faithfully until
something that was broken before self-destructed again.  In the
meanwhile, it never siezed in the snow, stayed clean inside, and
shifted reasonably well for a derailleur of its day.

My old roommate was flying down to florida for vacation last year and was
going to take his bike.  When i told him that he should expect to pay $45 each
way he was upset!  he ahd a bike box from our local bike shop, but we painted
it a bit and wrote "scuba gear" on the side (which wasn't a lie, there was
some scuba gear in the box).   on the way down  the box wasn't questioned, but
on the way back they looked at him funny and asked if he was sure there wasn't
a bike in the box.  they also mentioned that scuba gear, skis and surfboards
cost $$$ to fly, but eventually let himtake it along for free.

I guess if you are nice and catch them on a good day you can get away with it!

I am interested in your comments mainly because they contradict the
conventional "wisdom" I've encountered in the motorcycle world.  First

motorcycles intended for road use have been equipped with front and rear disk

First, some possibly misguided personal observations (in the context
of motorcycles):
	
It was only when drilling rotors was found to bring lag time during
wet braking within .5-1 second of dry braking with rotors that they
were mounted both front and rear.  I have always felt that in fact
disks provide much better energy dissapation that drums.  This is
probably due to the fact motorcycle rotors are larger than the rotors
on a small car whereas motorcycles drums are tiny.  In any case, this
fits with your observations on controllability.  Motorcycles require
powerful, highly controllable brakes, so a large disk would be right
solution, given that the wet braking problem can be solved.

Now, the question (in the context of bicycles :-):

Is it possible to have the rims designed such that they channels in
the sides to allow water to channel away under the brake pads on a
caliper brake?  We get enough rain up here in British Columbia to
make the question something more just academic interest :-).

Recently, I had my 1991 Bridgestone MB-4 bike stolen (see post).

Unfortunately, this means that I need to buy a new bike.
I am 6'6" tall and weigh around 215lbs.  I ride off road a lot and
although the MB-4 was a good bike for me, the 55cm frame was too small.

The Bridgestone MB-3 comp (from 1991 catalogue) was available in a 58cm
frame and the 1991 model listed for around $750.00.

If anyone has any advice (good or bad) as to other mountain bikes in the
same range that are available in larger frame sizes I would appreciate
it.

Also, any advice on getting more money back from the insurance company
($250.00 deductable!) or convincing Kryptonite lock company to make good
on their warrenty (the thief took the broken lock also).

Please respond to my address.

Thank you,

   Specious argument, I'm afraid.  The blind person can't help being
   blind, and being a pedestrian is not a notably risk-taking activity.
   The biker was killed not just because the motorist pulled out, but
   also because she was not adequately protected (no cage of steel)
   for travelling at 40mph.

So you would come to the same conclusion if the two-wheeler
had been a bicycle?  Of course the event was unintentional,
but because the driver did not see the motorcycle does not
imply even that the motorcycle was particularly difficult
to see.  An essential part of safe driving is looking carefully
before entering the roadway.  Many seem to assume that this
means giving a quick glance to ascertain that no one is in
the airspace that they want.  This is not enough.  Sure a
motorcycle offers less collision protection.  This does not
excuse negligence on the part of other drivers.  Pulling
into the path of an oncoming vehicle of any kind is an
act of culpable negligence by any reasonable standard.

It *is* an age-old can of worms, but I just gotta answer anyway.  Cyclists shave
their legs for all sorts of reasons, mostly bogus (no, I'm not gonna say which
are bogus).  But REAL(tm) cyclists do *not* shave their legs; they just go fast
enough to let the air stream blow the hair off.

companies not to offer renters' insurance to people who live with more than 
one un-related roommate.  I have two now, and may have more soon.  Can
anyone suggest a company who will make an exception to this "general policy?" 

I want to make sure that I am protected both at home and when I am out

One other question (which i forgot to ask my agent)...does anyone know of
some type of clause I could just tack onto my auto (yes auto :-) insurance
that would cover me while on bike?

I don't doubt that the terrain may be as described but the more "gnarly"
the terrain the less it takes to skid a wheel.  If you had said you were
descending a steep and winding paved road I could imagine brakes becoming
a chore to operate.  As you may detect, the average hand has a grasp of
about two inches and a strength that has been characterized by brake
manufacturers.  These two limitations have made all mainstream brakes
have about the same mechanical advantage that is derived from stroke and
force.

Therefore, brakes generally have a mechanical advantage of 4:1 and this
is achieved at the hand lever.  You can measure this by the lever length
from the pivot to the crook in the lever and the pivot to the cable
attachment.  Calipers or other linkage is close to 1:1 so that the each
move about 1/8 inch per inch of lever travel.  The big differences in
brakes are elasticity and friction.  Both of these affect feel or
responsiveness and therefore dependability in difficult situations.
However, more braking power is generally not a the problem.  Or, more
precisely, most lack of braking power is in fact poor control since
almost any brake pads can be put on most brakes.

Brakes with servo assist such as the Scott self energizing brake are
what automotive brake designers abhor.  Such brakes deliver a retardation
that is not proportional to hand lever force.  They are dependent on
on the coefficient of friction and have a multiplying factor that can
lock up a brake if the rims are sticky.  Motorcycles use disk brakes for
this purpose because drum brakes, although more powerful, are self
energizing and, therefore, non linear and less predictable.

In summary, if your brakes don't stop, get better pads but the primary
concern is a rigid, inelastic system with low friction.  They all have
about the same mechanical advantage.

I havn't used tubulars, so I can't addresss the weight and
smoothness question.  For tires, Continental Super Sport Ultra's.  I
use the 700x25c size, but they come smaller (from memory: 18, 20,
23 and 25, but check with a dealer for full details).  I'm heavy
(98kg), and ride on dirt, gravel, etc., so I need the wider size.
Very smooth, grip very well on wet and dry pavement, and dry dirt
(havn't tried mud, probably won't any time soon).  The Mavic
MA-2 rim is solid and reliable, but not the lightest on the market.
I havn't had a puncture yet on the SSU's (several hundred miles), so
tube quality hasn't been an issue.
