Today I tore down the rear wheel on my dual sport. There
was a lot of rust (from the spoke nipples), white aluminium
corrosion and dried mud that I brushed out.
Now this bike will see dirt, wet and even some salt. Is there
anything I can use on the inside of the rim to prevent
corrosion ?
And, do I use a rubber rim band (or whatever the English
word is) or do I apply duct tape over the nipples ?

A rubber rim band would probably be the best method, but duct tape
would work just as well. Has the added advantage of not slipping
during reassembly.

When I was rebuilding a set of wheels not long ago, I purchased a new
set of rim bands, one 18" for the rear and a 21" for the front.
Anyway, without thinking I installed the 18" on the front and was left
with a very loose fitting rear band. I couldn't be bothered removing
the tyre again to retrieve the correct band, so I used tape

Maybe someone else could suggest a method of preventing corrosion...

Regards,

Ben.

One problem is the aluminium reacting with the steel of the nipple. Find
some zinc paint ( try a chandlers ) and put a -thin- coat on the inside of
the rim where the spokes come through after you've cleaned the crud out.
Best long term solution is to replace the spokes + nipples with stainless
steel ones.

Duct tape is fine, but tends to lead to problems later on if you don't
remove it every now and then to check for any serious corrosion that may
have set in.

What about using a thin smear of petroleum jelly stuff, like Vaseline?
IIRC, I'm sure I found this already applied on one bike I had.

also 1 ripped off valve stem should teach you not to put anything slippery
on your rim............

The description in my question was a bit incomplete. You guessed
right, the rims are alumninium. The spokes are zinc coated and
going by the look and the lack of severe corrosion on the old
nipples I'd say they are zinc plated as well. Even Italians can get
corrosion protection right ;-) (The bike is a Yamaha TT600R
made in Italy).

Galvanic corrosion may play some part here. Mostly I think the
corrosion is caused by water, sometimes even salty water, that
gets inside the rim trough the nipple holes. It is by no means
catastrophic (yet) but why not try to improve on the situation?

I'm rather doubtful about the duct tape myself, I just wanted to
see what reactions I'd get from the collected wisdom here.
It would be nice to try and seal the nipple / rim area by some
sort of sealant but this idea is dumb as it would effectivly make
spoke adjustment impossible. The thinking at this moment is
to spray some car body rust preventer (vaxy stuff) into the
middle of the rim and before mounting a conventional rubber rim
band, at least I hope this will not cause problems.

?????
There's all kinds of sealants that are made to allow/tolerate adjustment
in the fitting afterwards. Products made for plumbing fixtures come to
mind (also called 'pipe dope' or 'Rectaseal' here in the US. Rectaseal
is a brand name). I can't speak to their corrosion resistance, nor to
their suitability here, but these products _are_ made to keep water out
of threads/joints. The stuff is also typically pretty cheap, and has the
advantage of staying put, which underbody sprays often do not.

FWIW

Please don't put that stuff in your rim. Just us a proper rubber strip

Seeing as this is a technical group, and I'm both dumb and very
inquisitive, I would appreciate some sort of reasoning or tale of
experience to explain your position.

The whole question was raised to try and improve on a problem
I've seen myself and I know I share with other people who
use spoked wheels in corrosive or wet conditions.
I already know the conventional set up and what to expect
from it.

Definitely an idea to think about. Even so, I don't think I want to
test it. Pipe dope would probably be a pretty successful sealant
and on piping, where you can apply a Stilson wrench (if my
English got that one right) there is no trouble to shift it. On
spoke nipples where it is difficult enough to overcome the
resistance in the thread after some exposure to the elements
the added friction at the nipple/rim contact might be too much,
I fear.

Please keep the ideas coming, it will be a few weeks before
the tyre goes on.
