Stages

  1. Take a tape measure and a thin, rigid support (a notebook, for example).

  2. Barefoot, place your backs against a wall, heels together and 5 cm apart.

  3. Place the rigid support between your thighs, making sure it's horizontal and in contact with your perineum.

  4. Measure the distance between the floor and the top of your rigid support. This will give you your inseam measurement.

  5. Refer to the table below to find the size of your bike that also corresponds to the size of the seat tube.
