Selle Italia SLR Boost Kit Carbon Superflow L3 saddle

The Selle Italia SLR Boost Kit Carbonio Superflow saddle is the most emblematic of Selle Italia. The SLR has been the reference point for style, performance, comfort and lightness for years and has supported great champions. Thanks to technology and the highest quality materials, such as 122 gram carbon, the SLR Boost is unsurpassed for its lightness. A refined aesthetic, combined with unparalleled comfort, thanks to its compact structure, the slight elevation of the back and the micro-perforated covering which helps to easily find and maintain the ideal sitting position, guaranteeing adequate support of the ischial bones and avoiding any problems of crushing.

*Thanks to Idmatch Smart Caliper technology, Selle Italia offers 6 size variants divided into two groups: S1, S2, S3 – L1, L2, L3.
Regarding dimensions, 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 sitting point to be 'unloaded', guaranteeing excellent comfort thanks to greater flexibility in the central part of the saddle.

The S1 and L1 models, suitable for cyclists without great pelvic rotation, do not have a 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 that produce pressure and friction during pedaling: elements which together increase the temperature in the sitting point and can create critical conditions and physical discomfort.

The third size - S3 or L3 - refers to saddles with a wide central cutout, recommended for cyclists with high pelvic rotation, which creates a lot of pressure and friction on the saddle surface.

With size 3, saddles with SuperFlow technology, i.e. with an even larger central cutout, are also available for cyclists who prefer a more comfortable feel.

In fact, SuperFlow technology drastically reduces all the discomfort caused by prolonged pressure in the pelvic area and allows you to always find an optimal and very comfortable sitting position.
