I was browsing the internets (there are multiple tubes, you kn0w) and came across this picture. I’m not sure how many bikes are designed this way, but more should be. I was impressed. I like the company that makes this particular bike, and this is part of why.
I’ve been in an engineering mood lately, reading a lot of Henry Petroski and thinking about designing stuff. Good time to exercise the brain in the offseason.

great stuff, Rappstar. I wonder if there is any ‘SimCity’ type software out there for bike design ? It would be a blast to tinker with angles, setback, etc. with such a program. Maybe I just gave myself a project…

There is indeed such a program out there. And it is free. From Slowtwitch.com: “There are plenty of good (and even free) resources on the web. The best (that I’ve found) among the parametric programs that would aid a framebuilder or designer is an Excel-based framebuilding tool by Martin Manning, called < HREF="http://www.frameforum.net/forum2/index.php?act=home" REL="nofollow">Body Geometry 101<>.
