If you are interested send me an email at lavs@peak.org,... I've made up a few spread sheets that let you easily play around with gears to see what gearing you might need for a certain mph, cadence, etc. I will send you a copy (Excel).
I also made up a sheet that compares crank length to watts produced, IF (Big IF) cadence and force on pedals can be maintained.
Potentially, after I get my Zinn compacts. I will have a set of carbon FSA 175mm Octalink cranks (sans chainrings) that will be looking for a good home.
