Selle Italia SLR Super Flow Saddle - TI Rails DO NOT USE
Selle Italia's SLR shape is a classic for riders of all disciplines and body types. The SLR Super Flow took the comfortable, supportive shell shape of the SLR and gave it a wide cutout to relieve pressure on your sensitive tissues. Factor in a sub-200 gram weight, and you have a saddle that's made for training, racing, or touring. The Super Flow maintains the flat, broad profile that's made the SLR a classic, but it's the sizable cutout that earns the Super Flow its name. As with most saddles incorporating pressure-relieving cutouts, the idea is to channel pressure away from your perineal artery and the adjacent soft tissue. 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 sensitive nerves in the region. For example, the pudendal nerve is a paired structure, with a left and right nerve. It is formed in the sacral plexus, and in simplified terms, moves down the body between the piriformis muscle and the ischiococcygeus muscles, eventually attaching to the ischial spine. From here it eventually enters the pudendal canal within which it divides off into several branches including the perineal nerve and the inferior rectal nerve. Keeping pressure off of these nerves is imperative to reducing numbness while riding. Because softer is not better when it comes to support from your saddle, Selle Italia used a modest amount of sensibly placed padding in order to ensure your comfort after multiple hours in the saddle. In keeping with that theme, the saddle base is built from a nylon-based composite, which incorporates a 30% mixture of carbon fiber. The resulting shell has the stiffness that's essential for support, but with enough flex built-in that it moves with your body instead of causing hot spots. Additionall...
