    Sturney Archer mystery part

    The studios have been humming once again. Here, I examine the actuator plate, aka, mystery part.

    The original 3-speed AW-NIG was designed in Nottingham in ~1984 for the Columbia Bicycle company. This hub did not have the actuator plate. An actuator plate made its first appearance in the 1988 AWC-NIG hub. If you have an old AW-NIG from the 1980s or 90s, probably best to not backpedal in high gear!

    Despite being used in the AW-NIG & SRF3 (2001-present), the StAr, Sprinter, Summit and (W) five-speeds, and the ill-fated 7-speed, the actuator plate is shown but not identified on the factory exploded parts diagrams. I don't know how universal this part is; the one used in the freewheel 3-speed hubs is an HSA470.

    Thanks Dan, enlightening as always.
    Any information, no matter how good, will always under-represent reality.

    Interesting bit of history as always. Thanks for that.

    Doh! I just noticed I fat fingered the title. Oh well, I think it's clear enough to be understood.
