LOL! What utter nonsense. Consider the source, I guess. He'll be out of business five years from now, I guarantee you....
Jobst is talking about isolated failures (which occur in ANYTHING man-made), and this clown says that means 100% failure rates? Poppycock! He obviously hasn't a clue what he talking about, which sure wouldn't give me any warm fuzzies about buying one of his tandems.

This is how the history of lugged bicycles is being told on the Tandem@Hobbslist. Strange.

Folks,
Someone pointed out to me that not everyone knows what a lugged steel fork is and why they frequently fail. These went out of popularity in the 80's because of there (sic) terrible rate of failure. These are brazed steel forks that the crown is a lug and the steel fork blades were brazed into it.
The rate of failure of the blades at the lug after XYZ number of stress cycles was pretty much 100% because of the flex on the blades were they entered the lug. Maybe some of you engineer types care to elaborate?
Jobst Brandt does a better job of describing it at
