Bike Size Calculator

Based on the fit guide from The Colorado Cyclist, Inc. that is based on "LeMond's formula".

Calculate
Inseam (?)

To determine your proper frame size, you'll first need to get an accurate inseam measurement . Stand with your back against a wall, your bare feet 6'' apart on a hard floor, looking straight ahead. Place a book or carpenter's square between your legs with one edge against the wall, and pull it up firmly into your crotch, simulating the pressure of your saddle while riding. Have a helper measure from the top edge of the book to the floor, in centimeters. (You can convert inches to centimeters by multiplying inches by 2.54.) Repeat two or three times, for consistency, and average the results to get your inseam length.
