Frame size calculation using the coeficient

Before ordering the frame you can get its probable size. The result is calculated from these two parameters:

• body height,
• limb length.

If both calculated results are equal, it is not necessary to do a special measure. If there is difference greater than 1 cm between this two values, it is better to consider the result of body height.

In case of difference greater than 2 cm, it is recommended to use our FOG measure.

Notice: To measure racer's limb length, let him spread his/her legs slightly forced down to the seat, and then take a value from the ground to his/her fork.
