    Quick Sturmey Archer Technical Spec Question

    Hey there,

    I just have a quick question about the technical specs listed on SA's website about the S2 hub. They list the PCD (pitch circle diameter) as 67mm. I'm assuming they're referring to the hub flange diameter, as in the distance between the center of one spoke hole to the center of another directly across from it? Because they also list a flange width of 53mm. Correct me if I'm wrong.

    Thanks guys!

    that would be the diameter.. though It more likely is the center line that runs through all the holes around that circle.

    rather than hole to hole,. because they may not be directly across 180 degrees apart.
