The Selle Italia SLR Max Gel Flow Saddle is proof that a happy medium exists between razor-thin racing saddles and an over-padded pseudo-sofa. Building on the legacy of the mid-width SLR shape, this saddle prioritizes comfort with an anatomic cutout, gel padding, and built-in shock absorbers. So, if you need a smoother ride from your saddle, this perch provides it. The foundation of the SLR is its nylon composite shell, with its 'composite' designation being derived from its 10% carbon fiber content. Essentially, this mix provides the shell with a boost of support, while still providing a natural level of flex for comfort. However, as it does share SLR designation, it dimensions vary from the boilerplate 131mm width and 275mm length to a 145mm width and a 275mm length. It also differs is in its level of padding. Selle Italia ranks this saddle as an 'L3' in its Identity Matching System, meaning that it possesses a similar level of firmness to SLR Super Flow and the Max Flite Gel Flow saddles. In terms of padding, you'll find that the SLR is quite ample. In fact, the L3 designation is reserved purely for comfort. And, in addition to this, Selle Italia also gave the SLR a shock absorber. This makes it ideal for those with large-width sit bones and high pelvic rotation. And for anyone who also prefers a medium-profile design, the SLR has one of the higher measures from rail to top-of-cover in the Selle Italia line (57mm). Further differentiating itself, the Max Gel Flow features an ample-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...
