Selle SMP crafts its Forma saddle in the same vein as the Composit saddle but in a slightly wider width perfect for those of us with broader sit bones. The innovative shape and pressure-relief channel are fully intact and without any excessive padding. This keeps weight and bulk to a minimum while maintaining the shape and supportive characteristics SMP saddles are known for.The Forma sits at 137mm wide and is best suited for medium to large pelvises and it features a thinner profile than other models in this range. At the front of the saddle is the characteristic beak nose shape designed to relieve pressure while seated. SMP's pronounced "free" central channel, further reduces pressure on the pudendal nerve and surrounding soft tissue. The back of the saddle is raised to support a powerful pedaling position, where body weight is divided between the rear and lower part of the ischial tuberosity region. This shape also helps reduce overall pressure on the coccyx while riding over rough surfaces.The saddle is wrapped in leather on the black version and a durable Lorica microfiber on the colored versions. Its durable elastomer nylon and carbon composite shell is supported by stainless steel rails so you'll have a secure and durable perch that'll hold up to both road and mountain applications.
