THE CHOICE OF THE FRAME

Measurement method:

  1. Stand barefoot next to the wall.
  2. Measure the distance between the ground and the crotch.
  3. Multiply the result: - by 0.57 for a mountain bike - by 0.63 for a trekking bike - by 0.66 for a road bike.
  4. This should be divided by 2.54 if you want to get the value in inches. This value represents the size of the frame you should be using.

These calculations are very general, considering the number of possible biking styles that humanity has invented.

General recommendation due to body height:
