An anthropometric measuring tool for determining body measurements and selecting a saddle size. Its scientifically validated algorithm provides an individually tailored solution in 30 seconds, intended to support riding comfort and performance.

Determine the correct size in 3 steps

• Intertrochanteric distance measurement. The intertrochanteric distance is the space between the two greater trochanters of the femur. These support points must align precisely with the saddle surface and are an important factor in establishing a cyclist’s suitable seated position.
• Thigh diameter measurement. Measuring the diameter of the upper thigh and comparing it with the intertrochanteric distance helps determine the most suitable saddle shape for each cyclist.
• Pelvic rotation measurement. Knowing the pelvic tilt or rotation helps determine which type of saddle will provide the most comfortable ride.
