700 x 23c circumference

You may want to check out Sheldon Brown's Cyclecomputer Calibration Chart,
he's got 2097 for that tire size with a different make of computer, so
you're close. It's at http://www.sheldonbrown.com/cyclecomputer-print.html

My preference is to fill my tires to the recommended pressure, place the
valve stem over a crack in the sidewalk or a mark I can measure from, then
get astride the bike so you have your normal weight on it and roll it for
one revolution of the wheel. Mark the point where the valve stem is now
then make the measurement for the cyclecomputer from the mark you started.
If you don't have a tape that does metric, it's 2.54cm per inch. I set my
computers up for MPH so my measurements are often in inches anyway.

get the documentation. Can anyone confirm the figure I have of 2096mm for
the circumference of a 700x23c?

Thanks Lon,

I'll give it a try.
