Refined aesthetics, combined with unparalleled comfort, thanks to its compact structure, the slight back elevation and the micro-perforated cover that helps to easily find and maintain the ideal sitting position, ensuring adequate support of the ischial bones and avoiding any crushing problems.

*Thanks to the Idmatch Smart Caliper technology, Selle Italia offers 6 size variants divided into two groups: S1, S2, S3 – L1, L2, L3.
With regard to sizes, the S saddles are all quite narrow, i.e. with a seat width of 131 to 136 mm while the L saddles range from 145 mm to a maximum of 150 mm.
The number associated with the size (1, 2 or 3) identifies the presence or absence of the central cut (Flow technology): a special anatomical cut that allows the seat point to be ‘unloaded’, ensuring excellent comfort through greater flexibility in the central part of the saddle.
The S1 and L1 models, suitable for cyclists without a large pelvic rotation, do not have the central cut and therefore do not need to relieve the pressure and friction created in the saddle.
The S2 or L2 saddles have a small central cut and are suitable for cyclists with a medium pelvic rotation who produce pressure and friction during pedalling: elements which together increase the temperature at the point of sitting and can create critical condition and discomfort on a physical level.
The third size – S3 or L3 – refers to saddles with a large center cutout, recommended for riders with high pelvic rotation, which create a lot of pressure and friction on the saddle surface.
With size 3, saddles with SuperFlow technology, i.e. with an even larger centre cut, are also available for riders who prefer a more comfortable feeling.
