I've got half a dozen Stronglight cranks at home.
Some are 3 arm steel 116 BCD
While others are 5 arm aluminum with 122 BCD & 49 BCD.
Does anyone have a timeline for Stronglight cranks?
I'm trying to allocate them to some old frames and would really like to know during what years each was produced.
Another thing I'd like to know is how many variations of the 116 BCD steel 3-arm crank there were. Mine range from crude (as found on Peugeot UO-8s) to very refined (radiused edges and fluted arms). All 116 steel cranks look like they came off the same production line but the nice ones look like they got special treatment.
