I really miss my 1977 double-butted lugged steel Fuji S-10-S frame. Both seat stays broke a couple of years ago and instead of having the frame welded, I rebuilt the bike on a different frame, and unfortunately failed to keep the original frame. It's just not the same smooth ride anymore.

Also, I agree with Dahon.Steve -- many of the new aluminum frames ride really harshly, that's really the only reason the manufacturers have started equipping bikes with suspension forks and suspension seatposts, but they sell it to *consumers* by making it sound like you're getting something new and special...anyway, the added weight of the suspension components just about negates whatever weight was saved by using aluminum instead of steel in the frame in the first place...
