The new Specialized Power Arc Expert saddle expands on the success of the original Power saddle. It features the same channel, length, and hollow titanium rails as the original and Pro Arc, but where it differs is in its shell and padding. But this means that it still features a stiff composite shell and supple, Level 2 PU padding. The shape of the saddle is also designed to provide ample sit bone support, and this has been coupled with a shorter-than-usual nose section to keep pressure off of soft tissue while riding in aggressive positions. We even took this ideology a step further via an extra wide and elongated Body Geometry channel that\'s been proven through blood flow testing and pressure mapping to reduce numbness and pressure on unwanted areas.And while this all seems familiar if you\'re already a Power loyalist, this iteration features a curved Body Geometry shape that better contours to your body. What does this mean for your ride? It means that you\'ll feel as if you\'re “in the saddle,\" not on it. And ultimately, this equates to greater comfort and superior performance in all seated positions, whether you\'re a man or woman.Key Features:Patented Body Geometry design is lab tested for both men and women to assure blood flow to sensitive arteries.,Lightweight and supportive PU padding for comfort and support on longer rides.,Lightweight, durable, and hollow titanium rails.,Level 2 padding: Medium density foam for bike feel with additional cushioning.,SWAT™-compatible mounts moulded into the saddle base allow for sleek and integrated storage solutions.,Size 143mm / Weight: 243g,Size 155mm / Weight: 256g.
