Wheels, rims and things... suggestions

[quote="Jon Hemming"]Sheldon Brown has the answer:

[quote]Nipples are commonly made of nickel-plated brass. This is a good material choice, because brass takes very smooth threads, and brass nipples don't get corroded into position too easily.
For light-weight, high-performance wheels, aluminum nipples are available. Aluminum nipples do save a small amount of weight, and they can be quite reliable if used properly. They should only be used with rims that have eyelets of some material other than aluminum, because aluminum/aluminum contact between rim and nipple can result in chemical welding, immobilizing the nipples.

As Sheldon said. Plus Aluminium Alloy has no fatigue life, and doesn't roll into smooth or particularly strong threads.

The upshot is - aluminium nipples need replacing about every two years. The weight saving is about 20g per wheel (the difference between breathing in heavily and lightly is estimated at approximately 50g), so one splash of mud will negate any difference.

Brass is the way to go.

Now that's settled, I just need to look at prices...
