Direct Fit was developed by Gary Klein who felt that having a rider stand over a top tube wasn’t a very scientific approach to fitting a person on a bike. As a result, Klein invented a system that many in the industry have embraced over time. Klein’s Direct Fit philosophy analyzes how your body interacts with a bicycle to optimize comfort and fit. Klein continues to pursue this as a universal measuring/fit approach to improve upon and possibly replace the industry’s norm.
Direct Fit measures the distance between one’s hand position on the handlebars to the center of the bottom bracket (see diagram). Once you have this measurement, record it. It will never change no matter what bike you are on; no matter what position you are in throughout the pedal stroke. This distance remains a constant, on or off the saddle.
The included angle created by the Direct Fit line and the horizontal line of the ground helps determine the rider’s desired posture depending on the intended use of the bike. If it’s an acute angle, your back is flatter and your goal is an aggressive road racing posture. As the angle opens, the rider’s posture becomes less aggressive and more relaxed.
Proper fit is essential to performance and endurance. Be sure to work with your local dealer when purchasing a Klein bicycle.
