In 1972/73 I was working at a shop that sold quite a few all Campy bikes. I had a lot of customers come back with broken (not stripped) Campy seat lug bolts. Determined to find an solution, I developed an "unbreakable" seat lug bolt which I produced in 5 lengths in both black oxide and chrome plate finish. I sold many thousands of them including many to OEMs. It was one of the first Jevelot products. I only made the bolts to fit a 1/4" hex key on both sides, so I had to put up with ribbing from Don Millberger of Bicycle Research, among others, about about how the bolts were "not metric like Campy". True enough, but they didn't ever break.
