If you were a big fan of the original Power saddle, you might be pleasantly surprised by how much more comfortable it can get. The Power Arc Expert Saddle features the same channel and length as the original, now with curved Body Geometry technology and more durable Hollow Ti rails. What does this mean It means you can ride for miles with an in-saddle feel, as opposed to a stiff, uncomfortable on-saddle feel. Body Geometry provides personalized comfort and support that's ergonomic and lab-tested. Lightweight padding is strategically placed to alleviate pressure and assure blood flow to sensitive arteries, in men and women alike. Body Geometry saddles ensure proper support when riding in the correct position, and they come in multiple widths to support differing body types.
