Richard Cielec asks about a crankset:
I have that crank from a dumpster dive Trek of Ishiwata tubing. I have never seen a Campag 3-pin before and know nothing about them other than finding replacement rings - hahahaha. Is this a 3-pin Gran Sport ? Anyway...
Looks like a very crude piece o' work for a Campagnolo component.
Were these O.E.M. on any bikes ?
++++++++++++++++ My memory, which may not be terribly reliable, were that these were sort of second-source for some mid-level bikes. Sort of what you used when you couldn't get the NERVAR Star or TA three-arm. I haven't often seen them, but the finish wasn't bad. Yours may have had a hard life before moving to the dumpster. Their beefiness, though, made them look really klutzy when compared with the lovely, elegant Campy steel 3-arm equivalent with alloy rings.
