I've purchased a few wheel-related tools lately, including the Park wheel dishing gauge, and have a general question about wheel dishing.

On my existing two bike's rear wheels I can simply measure the amount of offset as set up by the factory and then duplicate it. But if you are starting from scratch with a frame, cassette and a bare rim . . . what steps do you take to determine the amount of dish required?

Are there published offsets for cassettes/wheel combinations? What about frames' specs?
