Spoke Size / Spoke Length Database - What size spokes do I need?

Hey buddy,

For the Miche Primato Large Flange hubs on Mavic Open Pro's i get 293.0mm for the front and 293.4mm for the rear so i'd order 292mm spokes.

Edd is back online.

It gives the front exactly as you stated, 293mm, but for the single-fixed rear I have, the measurement are 294.4 (left) and 292.6mm (right).

I trust it makes sense, but thought to ask.
