|Handlebar mount for Versalog 1460 Multi-function bicycle computer|
I finally got around to road testing my bicycle computer, a Post Versalog model 1460 made in November, 1956. It is of laminated bamboo construction, with a celluloid slider, and engraved markings. More complete information about this versatile and powerful calculating machine is available on this site.

A brief sampling of its many and varied capabilities include:
- Bicycle gear inches, gain ratio (see Sheldon Brown here)
- Frame mitres, angles, and tube lengths
- Trig, engineering, physics, chemistry, bridge design, trajectory, orbital mechanics
- Sustainable and eco-friendly! (renewable bamboo construction, no batteries)

This post brought to you by the One Speed: GO! Institute for Retrogrouchery Studies (OSGIRS) where our motto is "HEY! You kids locked up in your rooms texting and tweeting! Come stand on my lawn! I have sports equipment including but not limited to bicycles, baseballs, footballs, frisbees, lawn darts (the old heavy dangerous pointy type!), volleyballs, and even badminton, and I invite you to go to a place called "outdoors" and enjoy what used to be called "physical activity." Please note that some math may be taught in the process. Those allergic to fresh air, sunshine, physical activity, and the actual physical presence of other humans should take necessary precautions.
