Eddig azt hittem értem az angolt de ezt nem tudtam megfejteni hogy pontosan hogyan értendő
Along with the inseam, this is another of the critical measurements. You will need a pen/pencil/marker for this one. Sit down and then roll up your trouser/pant legs and find the center point on the inner/medial side of the knee and mark a little 'x' in this spot. This is the point that would be the centre of a line if you were to draw one from the back of the knee to the tip of the knee cap. Now make sure your lower leg is perfectly straight and measure from the floor to the mark you made on your knee. NB: If you suspect you have different length legs then do this for both legs and average the measurement. This value is your lower leg length and it is used in combination with your inseam measurement to help determine correct saddle setback!
