The following is required:

• Measurement card board
• Marker
• Chair without padding with a level seat area (this area should be as hard as possible)
• Ruler or gauge

Seat bone distance – from center to center

Important:

The calculated dimension is always the minimum width. When in doubt, select a saddle that is a little wider! It is also important, to prevent the selection of a saddle that is too narrow. A slightly wider saddle can in some cases (trekking/city) be more comfortable due to the larger contact area.

This is how it works

1. Put the measurement cardboard (flat side down) on a chair and sit on it.
2. Arch your back and possibly go on your toes to push the seat bones further out.
3. Pull yourself down onto to the seat area with your hands to increase the pressure on to the measurement cardboard.
4. Get up. The seat bones have imaged themselves on the waves of the cardboard. The impressions can be clearly marked with the marker. Mark the center point.

After obtaining seat bone distance add 0 cm to 4 cm according to riding position.

Cyclists who ride only up to 30 min. need soft saddles 621 soft or 603.

For longer rides we recommend all other SQlab saddles. To keep the familiarization of the seat bones ride at least every two weeks.

For sensitive sit bones we recommend the active series.

Seat bone prints with different sizes, left and right, indicate pelvic malposition. In these cases the active series is the clear solution.
