Creaking KH cranks (I think i have a new problem)

Take out all of the bolts on that crank. Then get red loc-tite and
spread it on the screws. Put in the pinch bolt first, then the other.
Make sure you get them super tight.

Speaking of which, either my KH24 cranks or hub makes funny noises
everytime I use them when it's below minus 20 degrees Centigrade.
Actually they start making noises about minus 17 degrees. I wonder if
this sort of cold weather riding was in Kris Holm's design specs.

Even so, after hours of sitting in front of the school in minus 20, I
can still hop right on and everything works just fine.

The only problem I have is that my uni tire pressure is just fine inside
in plus 22 degrees, but the tire is a bit flat when I get it outside. I
guess I just need to increase my tire pressure for winter riding.

Is there a temperature that will actually damage my KH24? It's gotten
down to minus 45 degrees in this are, but minus 30 is usually the
coldest part of the winter.

Remember that an isolated fluid volume will decrease when cooled,
meaning that the pressure in your tire drops with the temperature.

Also, chromoly (the axle material) and aluminum (flange material) have
different moduluses of expansion/contraction. This means the for every
10 degrees of temperature drop, the chromoly will shrink, say, 0.01mm
for every 20mm of material. This means that the axle in your hub may be
shrinking faster than the aluminum, meaning that it can become too small
for the hole and then produce slop. This could be what's happening.

It's hard to guess what's wrong based on your description.

You might consider taking the unicycle to a local bike shop that has a
good reputation for their repair department, and have them look at it
and try to figure out what's wrong. They should be able to figure out
if it's a problem with the crank, something wrong with the spacers,
something wrong with the hub, or something else. Print out pictures
from Steve Howard's 'Dissected KH Hub gallery'
(http://gallery.unicyclist.com/KH_hub) and show them to the bike shop.
Explain that there have been problems with the hub axle slipping and
creaking in the hub body and that you're concerned that your hub may be
affected. They should be able to determine if that is happening with
your hub.

Once you figure out what is wrong then you can figure out what to do to
fix it. If it's a slipping hub then contact the store where you bought
it and see what they suggest to do. If you got it from Bedford or
Unicycle.com, they'll know what to do.

I didn't think it was that cold yesterday around 0 - 5 degrees celsius.
But I was on it later in my house (riding front door to back door so it
could be put away in the porch, I wasn't quite that board) it was
sitting for a while so it was warmed up and it didn't creak go figure.
It must be that temperature thing, any ideas? Thanks everyone.
