If you need the shape and support of a racing saddle, but find that their stiffness is far from comfortable, then the Selle Italia SLS Kit Carbonio Flow Saddle is right up your alley. It builds on the classic SLR shape, but it prioritizes comfort over weight. To achieve this, it features a softer-flexing shell and additional padding. Additionally, it's rated for both road or mountain use, so it'll take whatever you throw at it and keep coming back for more.

The SLS sits on a reinforced nylon composite base that incorporates a 10% blend of carbon fiber. This adds to the shell's level of support, while also allowing a controlled degree of flex. The base utilizes the same 131mm width and 275mm length as Selle Italia's beloved SLR, only the shell is softer than most of the SLR lineup in order to provide a more forgiving feel. And this feeling is bolstered by an extra helping of padding, which makes the SLS an excellent option for long rides.

Further differentiating itself, the SLS Flow features a moderately-sized cutout along the center-channel of the saddle. As a result, that pressure is directed to your sit bones (ischial tuberosity), which are far more adept at supporting your body weight. Additionally, they're able to do so without causing numbness during long rides. This principle is further supported by the wide cut out, as it removes pressure from the pudendal nerve. Essentially, this is a nerve that runs from around the third vertebrae, all the way down towards your foot. And when compressed at the perineum region, it is one of the major contributors to numbness. So, by relieving the very threat of pressure, your blood flow remains consistent, eliminating numbness.

To minimize chafing, while also increasing durability, Selle Italia incorporated a microfiber cover. And supporting the saddle itself, the SLS features Selle Italia's Manganese Tube rails. Along with being lightweight, these rails strong enough that Selle Italia rated the SLS for mountain bike use.

The Selle Italia SLS Kit Carbonio Flow Saddle is available in a 131x275mm size and in the color Black.
