A saddle is more than just something to sit on. It's a key interface between you and your bike, a place where you can feel the road underneath you and exert control over your steed, so having a saddle that suits your physiology and riding style is important. Selle SMP's Evolution Saddle is designed for riders with average to narrow pelvises, as it has a relatively thin profile, only moderate padding, and Selle's trademark beak shape, which is designed to remove pressure on your you know whats. Strategically located foam elastomer padding and a pressure relieving central channel provide support in some key areas and space in others, while the raised tail of the saddle provides a powerful platform for seated pedaling. Depending on color, the Evolution is wrapped in smooth leather or durable Lorica synthetic. The nylon and carbon composite shell provides a firm but not brutally stiff platform, and the steel rails are durable without adding excess weight. Even better, the Evolution is versatile enough for both road and trail riding, something not too many other saddles can claim.
