Friends describe me as having "started off slow and then tapered off." I'm somewhere between relaxed and comatose.
There are lots of combinations of Campagnolo spindles (axles) and cranks.
"1978 - C.P.S.C. (Consumer Product Safety Commission) mandates changes to NR/SR. Included are a front derailleur lip, 2.5 mm increase in spacing between crank spider and arm to clear the front derailleur lip with corresponding increase in bottom bracket axle length..."
There's large bump and small bump cranks (ref to area around back side of axle hole). And on and on...
You just got the wrong mix of the old stuff (no need for the modern spindle [axle] in other words).
