Rash from hydration pack straps

I sure wish they would. There's tons of wasted space in the larger
hydroform tubes.

I also have an old German mountain-climber pack, about 50 years old. All
natural materials so maybe I just wear that for a ride. It'll look
funny, a guy on a new-age MTB wearing a caveman-style backpack. It even
has leather holders for a shovel and a pick-axe.

According to your descriptions of your commuting route, those could come
in handy! ;-)


Yup. Will be on one of those routes again later this week :-)

Yeah, so? It's happening under the straps, right? You sweat there,
and straps can cause the irriitation, and can block the sweat glands,
which is what causes pricly heat. Try an antiperspirant on the parts
effected.


It also happens (though to a lesser extent) when not sweating at all.
What did help a bit was covering the straps with plastic wrap (like Jeff
suggested) under the cotton sleeves my wife already made for them. I
tried that out yesterday. Only thing is, that concoction makes me look
like a bum. Have to figure out something decent-looking.

Fill the frame with helium. It will make the bike feel lighter.

It might be useful to pressurize the water bladder with compressed
air. That will allow you to put the bladder and hose lower on the
bicycle, so that you don't need to suck as hard to move the water. I
don't have any bright ideas exactly where to locate the water bladder,
but pressurizing provides more location options. Maybe one of these:

with a modified hose and coupling.

And soon it'll be airborne :-)

I don't care about that. I could mount a spigot and just use it to
refill my handlebar bottle. But there's hardly any space on my MTB.

Some day I wan't to use what little space there is in the bottom
triangle for a decent battery and tool compartment. On my road bike
there's tons of space. The nice thing about the backpack is that I do
not have to plan ahead. I can just hop on either bike, whatever is
better suited for the ride.

Here's a better approach:

but replace the cans with standard water bottles. It provides up to 85%
reduction in dehydration fatalities.

So, that tells you that you're reacting to something that comes out of
the strap (or the foam inside it). Cut 'em off, sew something else
on. Or buy a different pack.

Goodness! 85% more safety with the cans plus the original 85% safety
of the hard hat equals 170% safety.... One world live forever :-)
