I recently saw this picture from the North American Handmande Bicycle Show when Jeff posted it on his blog, and immediately had one thought (which was quickly echoed by Erik, whose site I visited after he posted a comment here):
Damn, that looks impossible to keep clean.
I mean, seriously. How many of us even floss regularly? Who has time to deal with this thing?
Can you imagine taking this sucker down a trail? You'd need dental picks and Valium just to get through the post-ride cleaning. And don't even think about not cleaning it, 'cause the crap that would accumulate in that freakish exoskeleton of a frame would more than make up for any weight savings achieved by using less tubing.
I'll tell ya one thing, though. I'd like to hear the sound that sucker makes when it's on a roof rack flying down the highway at 70 mph.
