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 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
