C Record experts, step up please!
I came into a solitary Campagnolo (left side) crankarm. From the shape I immediately thought of C Record, more about the shape later.
It has an engraved Campagnolo shield. it has a date code '4' in a circle: 1984.
I compared the shape to a C Record chainset I have with date code '52' in a square (c. '89?): the 1984 one is very similar, almost identical, but decidedly slimmer. The end with the pedal hole has a chamfered inside, unlike the beefier and straighter form of the later C Record.
C Record was introduced to the market in late 1986, or 1987, right? Prototypes were from 1984? I know there were prototype Delta brakes in 1984.
(I read this thread:
http://www.bikeforums.net/showthread...se-Campy-Parts , it doesn't answer my question)
So what is this? Any input would be nice, even though someone might reveal that this is not C Record ...
