SQlab was the first producer of bike equipment to develop the saddle width system to measure the sit bones and calculate the optimal saddle width.

Find the right saddle

quick and easy

All SQlab saddle models are available in up to five different widths. This guarantees that your sit bones completely rest on the saddle and relieves the perineal and pubic area. Determine the right saddle width now:

Measuring Set

free of charge

You don't have the possibility to visit the shop or you prefer to measure your friends and family at home?

 Sit bone measurement at home

That's how it works ...

1. Step

Place the measuring cardboard on a smooth surface or measuring stool. Sit on it with a straight back and pull towards the cardboard. Please make sure that your feet are slightly elevated.

2. Step

Measure the sit bone distance from center to center and add the value for the respective sitting position.

3. Step

Select your right sitting position from the positions shown above and add the corresponding value to the measured sit bone distance.

4. Step

Select the saddle for your personal riding style and in the correct width.

Fitting saddle width

More power- less pain 

A saddle has to fit individually

Narrow saddle

Leads to discomfort to the sit bones and an increased pressure on the perineal area.

SQlab Saddle

The optimal saddle width guarantees that the sit bones lie completely flat on the saddle. This is the only way in which pressure is relieved on the sensitive area in men and on the pubic arch in women and ensures more efficiency.

A saddle has to fit individually. If a saddle is too narrow, it squeezes, and exactly where it shouldn't. In 2002, we were the first saddle manufacturer to develop a system for measuring the distance between the sit bones and calculating the optimum saddle width. All SQlab saddle models are available in up to four different widths. This guarantees that your sit bones rest fully on the saddle. Because only in this way can the sensitive perineal area in men and the usually lower pubic arch in women be relieved.

To date, SQlab offers the widest range of saddle models in different widths for every area of use.

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.

The SQlab saddle width calculation has been adopted by expert magazines for saddle tests.
