Determine your correct size in 3 steps:

Intertrochanteric distance measurement
The intertrochanteric distance is the space between the two big femur tuberosities; these two perch points must be perfectly matched to the seat surface and are a crucial factor in establishing a cyclist’s ideal seated position.

Thigh-diameter measurement
Measuring the upper diameter of the thigh and comparing it to the intertrochanteric distance allows us to establish the best saddle shape for each single cyclist.

Pelvic rotation measurement
Knowing the pelvic tilt/rotation helps us to know what kind of saddle will offer the most comfortable ride.
