OK, so after more research and scoping the spindle out with a caliper I'm pretty confident that a 113mm square taper spindle will give me a proper chain line. I thought I had found one on the Rivendell site, but it was JIS, and out of stock. Velo orange and Harris cyclery did not have anything either, except the phil wood spindles which I can not afford. Anyone know of another source for such an item?
