Campy CDA crank date code
I picked up a Campy Croce D'Aune gruppo last week. The date code on the
crank arms is 41 in a square. I haven't been able to find what year that translates to. Chas. |

I hope you don't mean to imply that it was made in 1981, because the Croce D'Aune group didn't hit until 1986 or so. |

Dear Chas, Could the "41" be just the minimum number of teeth? "1967: The Record crankset is changed to a 144mm bolt circle (41 tooth minimum) from the previous 151mm bolt circle (44 tooth minimum)." http://www.campyonly.com/history/timeline.html Cheers, Carl Fogel |

In this group, someone of vastly superior knowledge is always quick to correct such faux pas. |

Rings were available as small as 39t (didn't TA make a 38?). Hank |

Dear Guy, The mysterious "41" in the Croce crank showed up in another thread about three years ago: "Sorry, don't know what the 93 in the square means. My Croce cranks have a 41 in a box, so it's not year of manufacture." http://www.bikeforums.net/showthread.php?t=107929 They never decided in that thread what the "41" and "93" meant.

Hank, There are some after market 38T chainrings for 130mm BCD cranks but 39T is minimum for a 135mm BCD. The chain just about drags on the spider with 38T rings on a 130mm Bcd crank. Chas. |
