In a separate post I explained the important hub dimensions and how they are measured, as well as how spoke length calculator is used. Here I will just make a list of data for hubs that I have worked with – filling it up over time. For a more general info on the topic, see the post about bicycle wheel building basics. The table is sorted by manufacturers first, then by wheels (front hubs first, followed by the rear hubs). Adding a picture here for a quick reference:
Another good (and mostly reliable) source for hub dimensions is kstoerz.com – hub dimensions secton.
