I've always wondered why drop outs were attached tongue in groove rather than by a lug (i.e., a stay inserted into a cylindrical end on a dropout). A lug would seem a stronger joint and, could likely be engineered and machined to be quite light. Fabrication seems technologically feasible. Assembly seems no more difficult, perhaps even easier. A lugged bike might look more unified (and beautiful) in appearance with matching lugs at the frame ends and frame joints, rather than tongue in groove at the frame ends and lugs at the frame joints? Perhaps the KOF frame builders could weigh in here and explain why tongue in groove is preferred. I assume it must be superior for some reason, or it would not be done, but I'd like to understand why?

Wouldn't ya have to make different drops for each size frame to get the angles right if they were lugged? sam lingo pleasanton tx
