i hope that you are talking about a wet cell... like the kind used in a
car... if not unless it is a ni-cad battery you cannot recharge them.  to
recharge a batter you reverse the chemical process that produces the
current and unfortuantely in a standard dry cell battery a gas is evolved
in this reverse reaction.  and well as you can imagine the pressure inside
the battery builds up until you have an explosion and i think the acid is
sulfuric and fairly concentrated and that stuff has a serious attitude, it
doesn't get along very well with anything it comes in contact with
especially clothes and skin... so unless it is a wet cell or a battery that
specifically says rechargable don't put it in a charger unless you plan on
standing very far away from it and there is nothing nearby that might be
damaged by the acid...

The red liquid you are looking for is probably called Hibacleans(sp?)...
It is a very good cleaning solution available through any drug store.. 
and the solution is a bright red in color, the other solution, Betadine
(also available at any drug store), is actually brown in color and is 
also good for cleaning road rash... It should be noted that since Betadine
contains Iodine, it should only be used as necessary... It seems too much 
Iodine is not a good thing, so I would suggest using Hibacleans on every 
wound except for the most severe....

As a last note, using a mixture of H2O2 and water is actually a good cleaning
agent... Due to its oxidation of the lacerated area, it will kill most 
germs... This is the route I happen to use when cleaning minor road rash...
It was suggested to me by an ER doctor who I worked for...  If you use regular
soap just make sure it is cleaned out from the injured area... Unlike the 
other solutions, possible exception of Hibacleans (I just don't remember),
soap should not remain in or on an open wound since it can cause an 
infection....

I still vote for linseed oil.
Doesn't freeze anything up and serves the purpose of depostiting
platelettes in the spoke threads to make the interface with the nipple
like it is supposed to be.  I'd guess a pint would do about a
gazillion spokes.

Eeerrmmm....It might be me being thick, but I'm pretty sure..No scrub that,
I am TOTALLY CONVINCED that the only way to have a dishless rear wheel is to
have an asymmetric rear triangle, ie the dropouts are both offset to the right.
You then build the wheel on any old hub so that the rim is directly between the
flanges, giving even spoke tension both sides. Manitou MTBs (the rigid custom
ones) have this feature, using a custom 145mm rear hub. So as far as I can see,
it's custom frame time.

Either that or give up on the whole idea :-). Whaddya need a dishless wheel on
a road bike for anyway?

Mike.

I didn't know that Oakley gave credits for broken glasses. I have two

A much greater force is that of capillary attraction and surface
wetting by a fluid, especially on a surface covered with a fine layer
of dust as all outdoor objects are.  I think you will notice that if
you get a bit of butter on the newspaper at the breakfast table, that
an oily blotch will expand to a six inch diameter in less than a day.
Butter isn't even a homogeneous liquid (similar to spoke prep).

If you choose your rim and spokes appropriately, you don't need
anything to keep nipples from unscrewing.  I have seen a good book on
the subject that explains that in detail.  I recommend it.

About BB cups unscrewing... That's called precession and, if the
exercise doesn't embarrass you (as it did some who read this
previously), you can demonstrate it by making a circle with one thumb
and fore finger while rolling your other index finger around in the
opening as if it were planetary gear.  The roll will precess in the
opposite direction from the contact point.  This is also the effect
that unscrews pedals if not threaded R-R and L-L.  I find it amazing
that only Swiss and English BB's are properly threaded.  I have always
used "English" threads for that reason.

   I've been having a tough time with my SPDs.  The most minor seat

   my knees hurt.

   So, I'm going to upgrade to one of the other walkable pedals.  Both

   It looks to me like the TWT cleats will fit on the same

   Does anyone have any comments/recommendations on the TWT pedals?
   Should I expect that I'll have to get new shoes too?  If so, is the

When I've been treated by paramedics and at hospitals, they've used this 
red liquid that looks like blood.  Is good ol' Ivory good enough compared
to this?   Are there any medical experts (or at least people with some medical

I'm also considering the Aheadset when I finally get all of the funds together
for some shocks.  Still haven't made the decision about the Aheadset, but I
did see a little item in the latest Mountain Bike Action that applies to
Mr. Truesdell's comments.  A company named "California Escape" is making
foam/lycra/velcro pads for the top tube/seat tube junction (for shoulder
carries), and most importantly for the stem.  The padding for the stem is
called (quite appropriately enough) the "Nard Guard".  Priced about
$7, and worth every penny if you ask me.  California Escape: (714) 830-4468.

>I'm interested in building a non-dished rear wheel.  

The other answers circled around the theme of offsetting the hub horizontally.
So this is my chance to bring back  the subject of:

high-and-low flange hubs

as they are produced by Roval and Maxicar.

What's bad with the dish of a normal rear wheel?

The right spokes are steeper, so the tension of the left spokes 
has to be reduced. Therefore the left spokes are carrying less
of the dynamic stress of the wheel, thus  burdening the right spokes
which already have to transmit the driving force.
(summarizing here)

The force on the rim would be divided into equal parts
if the angle of left and right spokes with respect to the rim
(or the vertical) was equal. Euqal angles can be achieved by
(standard solution) spokes of equal length, rim centered between flanges
or
(hi/lo solution) rim not centered,
long spokes and a low flange on the left side,
shorter spokes and a high flange on the right side.

This way I would get an asymmetric, but dishless wheel,
without having to reposition my whole drivetrain.
I don't need eight gears, but I like seven; so my 126mm frame
is filled up and I can not offset the hub.

I think the idea is excellent for touring wheels,
and I need a new rear wheel since my brave old wheel has been nicked :(

So wheel experts of all countries, unite and tell me whether
the hi/lo concept is fundamentally flawed in a way I can not see!

To provide a counter experience, I use a glasses-mounted mirror
now.  I haven't decided if I want to switch to a helmet-mounted
mirror or not (or just buy clear glasses for night).  A handlebar
mirror is out of the question now.

It took me a week to learn to use the mirror comfortably.  Now it's
second nature.  I get a very large field of view, though I do have
to twitch my head to see directly behind me.  They fit kinda funny
on my Oakleys, but very securely.

Give yourself at *least* a week before you decide whether or not
to continue using a glasses-mounted mirror.
