I stumbled upon this a few days ago and it's been sitting on my screen, I like it so I wanted to share it with you guys. I was really surprised to see how close the two positions are to one another. One of the things I love most about road bikes is how simple and stable the basic 'double triangle' design has been over the past 100 years. What other designs (other than chairs) works so well and has changes so little?
