SQlab was the first components manufacturer to develop the saddle width system for measuring the sit bones and calculating the optimum saddle width.
Sit bone measurement
Step 1

Step 2

Step 3

Step 4
Select the saddle for your personal riding style in the correct width.
The following special regulations apply to saddles of the 621 City/Comfort model range:
Sit bone distance less than or equal to 12 cm >> Saddle width 18 cm
Sit bone distance greater than 12 cm >> Saddle width 21/24 cm
The perfect saddle for any bike
More performance – less pressure


A saddle should fit like a pair of shoes! If a saddle is too narrow, it will increase pressure exactly in spots where it shouldn’t. Back in 2002, SQlab was the first saddle manufacturer to introduce a system to measure the distance between the sit bones and to calculate the optimal saddle width. As a result, all SQlab saddle models are available in up to four different widths. This guarantees that your sitting bones lie completely flat on the saddle. This is the only way to relieve pressure to the sensitive areas in both men’s and women’s bodies that are affected by hard saddles.
To date SQlab offers the largest selection of saddle models in different widths for all areas of application. |
The effective saddle width
The specified saddle width is always that of the effectively useable area for sitting on, not the total width of the saddle. With all our SQlab saddles, the effectively useable area is maximised and as little as possible of the saddle width is sacrificed through a strong curvature.
This is how you can check your saddle width
Draw a projection line across the widest point of the saddle. The useable width is from those two points from which the saddle curvature drops off by more than 1cm on either side.

This measurement method has been adopted by cycling magazines that measure the saddle width in saddle tests for comparison. |
