SLR Boost TM Superflow Val di Sole

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."
