• I'm trying to work out the spoke length for some nondescript Shimano UG hubs.
    I've tried my best with the calipers and could do with some verification.

    Front hub:
    flange diamete - 41mm
    OLD - 100mm
    Flange to flange - 69mm
    hole diameter - 2.5mm (ish, the calipers weren't that accurate)

    Rim - mavic open sport:

    Spoke length = 292.3 = 292 or 293?

    Rear:
    Flange diameter - 45mm
    OLD - 125mm
    A - 45mm
    B - 32
    LF - 30.5mm
    RF - 17.5mm

    Rim - Mavic open sport:

    Spoke length
    L - 292.7 = 293mm
    R - 291.7 = 292mm

    Does that look right?
