just another way to build a bike. And an opportunity for some self-expression. And, no, just because I'm an old fart doesn't mean that I automatically assume that an expensive bike needs lugs (maybe...nah). And I think hips are sexy, myself.
And, there was a major manufacturer (Raleigh of America) that assembled bikes with glue and lugs (the Technium line) for years. Unfortunately I found them kinda ugly for my refined tastes (they were internal lugs). heh. Trek has glued its aluminum bikes together for over 20 years. Vitus actually glued its tubing into external lugs, and several other similar manufacturers (alan, etc) did as well. The glue is still holding up on those bikes in my garage...but I don't ride 'em much any more. Steel lugs are prettier. and I guess y'all are right. Sexier, too.
