How are measurements taken?

This part of the website explains how the different measurements are taken.

The basis for a correct position on the bicycle is achieved by precisely and accurately measuring different parts of the body. Cyclefit uses a number of devices to guarantee that the measurements are correct and reproducible.

The most important device is the so-called crotch length measurer, which measures the inside leg length. Although many other methods exist, the Cyclefit crotch length measurer guarantees a perfectly reproducible measurement by using air pressure.

The Cyclefit measurement consists of six body measurements

  • Crotch length

    The crotch length or inner leg length is measured from the ground to the inside of the crotch (pubic bone). The cyclist positions themselves without shoes and with one leg on each side of the Cyclefit crotch length measurer. The feet are placed on opposite ends against the basis of the crotch measurer. To obtain the crotch length, the device is pressurised. The correct pressure is reached if the crotch length measurer no longer rises during pumping.

  • Femur or thighbone length

    To measure the length of the thighbone and torso, the cyclist must sit on the Cyclefit stool. To conduct these two measurements, the Cyclefit sliding calliper is used in position A (with a round accessory).

    The length of the thighbone is determined by measuring the distance between the wall and the front of the knee. The bottom part of the spinal column (sacred bone) must be pressed firmly against the wall. The angle between the horizontal upper leg and lower leg must be around 90 degrees. The person’s upper legs must be positioned straight and parallel to each other.

  • Torso length

    The torso length is determined by measuring the distance between the seat of the stool and the point where the two collarbones converge with the breastbone. Make sure that the person’s back is straight and positioned firmly against the wall. The shoulders should not be raised and their chest should be relaxed.

  • Arm length

    The cyclist must stand up straight to measure their arm length, shoulder and feet length. To conduct these three measurements, the Cyclefit sliding calliper must be placed in position B). To measure their arm length, the cyclist must stand with their arms outstretched alongside their body; their fists must be clenched and their shoulders should be in a relaxed position. The back of the hand (fist) and the arm must form a straight line. The arm length is measured from the top of the shoulder (the hard part on top of the shoulder) to the (right) bottom of the clenched fist.

  • Shoulder width

    The shoulder width is measured by determining the distance between the outer points of the shoulders. The arms and shoulders must be relaxed.

  • Length of feet

    Lastly, the length of the feet are measured. This is the distance from the back of the heel (heel bone) to the front of the longest toe. The cyclist must stand to conduct the measurement! It is recommended that both feet are measured. If there is a difference, the longest foot length should be entered.

    In addition to these body measurements, your Cyclefit dealer must enter information on your gender, the type of bicycle and experience level. In addition to body measurements, a number of bicycle parts sizes must also be entered. This includes the saddle length and shape of the handlebars. All these parameters are entered into the Cyclefit system and used to generate a report with the information on the correct position.
