Here's crazy, I was thinking this morning on the ride in:

I wonder if people have come up with a pedal strike degree caculator.

You know, pedal strike is a possible problem on a fixie, and you should know to what degree you can lean before your pedal strikes the ground.

So, it'd need data like BB hieght, crank length, pedal width, pedal thickness..

The thing is, these math experts with a *****load of time on thier hands, they, they could easily figure it out and trump Sheldon Brown by coming up with it first!!
