Fit Calculator

We need 8 core pieces of information in order to calculate your optimum frame size and initial position. You'll need the assistance of another person to make the most accurate measurements possible. And don't be afraid to take each measurement 2 or 3 times and average the measurements together. Please keep in mind that the accuracy of the Fit Calculator is strictly a function of the accuracy of the information you provide! We've discovered over time that when the Fit Calculator provides off-the-wall fit output, it's a strong indication that the body measurements you've provided are inaccurate. Please take your time and be as meticulous as possible!
