Short guide to sizes
Our saddle sizes are characterized by a letter and a number, which combined offer 6 different options, to which the one-size-fits-all triathlon size, called U3, should be added.
The letters
S or L indicate the width of the saddle, and the guiding factor in choosing between them is the intertrochanteric distance (between the ischial bones of the pelvis).
Size S: narrow distance, for individuals with a value below 120mm
Size L: wide distance, for individuals with a value above 120mm
The numbers
1, 2, and 3 indicate the presence or absence of the cutout on the saddle, and the guiding factor in choosing is the rotation of the pelvis/body flexibility. For those with excellent pelvic rotation, size 3 is recommended, while for others, it is advisable to move towards size 1 in a descending order.
1: indicates a closed saddle, therefore the absence of the cutout
2: indicates the presence of a smaller hole called "Flow"
3: indicates the presence of the hole called 'Superflow' (the wider one)
Individuals with a higher level of stiffness can use size 1, but also sizes 2 and 3.
On the other hand, it is not recommended for a flexible individual to use a saddle without a cutout.
