The EVOLUTION model is the ideal seat for both races and cycling in your free time. It uses the structure of the Composit model joined with minimal padding. It is covered in real leather in the black versions and microfiber in the colored versions. It has excellent all-around features and is particularly suited for the average pelvis. The EVOLUTION model has foamed elastomer padding where the ischial tuberosities and rear rest. The patented features by Selle SMP, such as the completely free central channel, the original eagle-beak nose and the raised rear give these models an interesting aerodynamic touch. In virtue of its very small padding it is particularly suited for thin people with narrow pelvises.
