Just picked up a Nervar Star double alloy crankset which according to the Internet was original spec on Schwinn Superiors and possibly Sports Tourers in the mid/late 70s. I picked it up to do a lightweight town bike build on a very clean Continental frameset in my size, which means I'll be using a 1-piece to square taper adapter. However, I ran across a reference to the fact that this Nervar crank may require a special taper profile for the spindle (and therefore that the regular YST adapter spindle would not work). Any ideas as to the truth of this or any workarounds?
