Dear Ken,

Brass spoke nipples can be plated silver or black (and probably other
colors), partly for looks, partly for corrosion.

Doubts have been expressed about whether plain brass nipples normally
corrode, often in conjunction with rants about cosmetic foolishness.
Spoke companies ignore both the doubts and the rants.

DT Swiss offers brass nipples in either black or silver, the
difference being aesthetic:

Click on the black and gray rectangles to see the two different
colors.

Here's Wheelsmith's corrosion claim:

"Wheelsmith nipples are coated with a unique intermetallic substance
second only to gold for its corrosion resistance. Nickel or chrome
plating, once the preferred coatings for many bicycle parts, was
gradually replaced by superior materials, except on spoke nipples.
Duristan produces a brilliant, shiny surface with a slightly blue
cast."

It would be nice if someone could explain what Duristan is.

Cheers,

Carl Fogel

I have no doubt because the nickel plated spoke nipples I use. Flash
tin plated ones I once used lost their tin (a sacrificial anode as
zinc on corrugated sheet metal roofs that lose their plating) and
turned black as copper alloys do. The next step was that they turned
green in winter and made themselves hard to turn, being corroded
inside and out.

I think they are both nickel that can be treated to be black, often
called "black chrome" being mainly the nickel plate. Why waste chrome
if you don't need it silver sheen?

That's pretty hard to take! I'll bet it is tenacious as well. Don't
leave out any buzz words when writing this sort of stuff. Rick has
always been an expert at this.

As I recall Stnnum is:

# Alchemy Symbol

# The symbol for the metal tin was sometimes interchangeable with the
# astrological symbol for the planet Jupiter. Tin was also known as
# stannum, the name from which the element's symbol is derived (Sn).

Duristan would then be hard tin plating, if there is a hard version of
this process.

Uh, because of the chrome/UPC/Nickel plating? Is there a joke in there
some place?

Chrome plated brass. Chrome being the operative word.

Carl Fogel will be along in a mo' to recommend Stephen Jay Gould's "Male

Just for laughs I did a google search for Duristan. I got 334 hits,
most associated with spoke nipples. By the time I had added -nipple
-nipples -wheelsmith to the search I was down to 46 hits. The most
imaginative was the use of Duristan as a fictional country in a
scenario proposed by a site called "Interactive Adventures in Ethics".
