Be sure you factor in the small wheels. My bike's wheels are 650 x 23. What size wheels did your old Bianchi have?

Here's an interesting site where you can plug in all the data and get more geek data out.. Gear inches, Gain ratios, and certain MPH's at certain RPM's. Total geek stuff, but fun when you have a new toy to play with...
