Is it ok to use one odd spoke for a wheel build?

You don't need to mis-match, but if you choose carefully, you should be able to. D-light come in both black and silver (links are to my local supplier/wheel builder, but demonstrate that they exist). ...

Nipple replacement question

There is a lot to be said for 4, but 3 is best if you are going to do this. 1 is actively bad for the rim and there is nothing to be gained by 2 if you have a tensiometer. The conventional wisdom is ...

Will this modern road bike hub fit in my 1990's MTB (130mm restoration)

Is a spoke tensiometer useful for determining that a wheel is on its way to becoming out-of-true?

There are several diagnostic uses I use a tensiometer for fairly regularly: One is to get a sense of how good the tension balance and tension level on a wheel is as a way of evaluating if it needs ...

Glue in nipple seat in brand new rim?

How much do spokes stretch when first used?

What's special about spoke nipple washers?

The washers need to fit the rim. If the part of your rim where the spoke holes are, i.e. where the washers will sit, is not flat, your washers will sit on two points rather than on a flat face. As a ...

Is a spoke tensiometer useful for determining that a wheel is on its way to becoming out-of-true?

Not really. I imagine a high-end wheelbuilder has a blue wall of expensive park tools because that's what's expected by the high value customer. If a wheel might be suspect, my quick test is to spin ...
