The Selle Italia SLR line of saddles has a long tradition of durable comfort among cyclists of all levels. The SLR Superflow S Saddle lives up to this tradition and delivers even more comfort wrapped up in a lightweight package to get you through all the miles you want to ride. The Superflow S gets its name from the large cutout at the center of the saddle to relieve pressure on your perineal artery and surrounding sensitive areas. This cutout shifts the contact points to your sit bones, which are far better equipped to support weight comfortably. Say goodbye to numbness and hello to more comfortable saddle time. Selle Italia utilizes strategically placed padding layered over a 30% carbon fiber, nylon-based composite matrix to provide just the right amount of stiffness for support and just enough flex and padding to eliminate hot spots and keep things comfy. Additionally, the lightweight titanium rails double as shock absorbers at the back of the saddle to dampen road vibrations and increase the durability of the saddle. The Selle Italia Superflow S Saddle is available in a long, narrow profile to provide a wide range of positioning options to riders of all disciplines. Riders with wider sit bones may prefer the Superflow L Saddle with its wider, 145mm stance.
