Saturday at about 70 miles into a century I looked down and saw a fine hairline crack forming on
the drive side crank arm. My beloved 1980 Super Record crankset is now just a very pretty paperweight.
Even though I'd filed the stress concentrating sharp edge at the base of the arm where it meets the spider long ago, the accumulated years and miles where too much. I'm just glad I saw the crack when I did, losing a crank arm at speed would be an ugly moment indeed.
So, if you're riding old Campy cranks, keep a lookout for the dreaded crack of death!
