The S-works Power with Mirror technology is the perfect reflection of you. We’re redefining comfort & performance with Mirror technology to take Body Geometry into the future. The last big material innovation in saddle design happened decades ago with the introduction of foam. To develop a next-generation saddle we had to look beyond foam & develop a next-generation technology. The S-Works Power Saddle with Mirror is the future. We developed Mirror technology by 3D printing from a liquid polymer to perfectly reflect your anatomy. This revolutionary process creates a complex honeycomb structure that allows us to infinitely tune the material’s density in a way impossible with foam. The result is a patent-pending matrix of 14000 struts & 7799 nodes each of which can be tuned individually. & when you combine this technology with our extremely lightweight S-Works Power saddle with its flexed-tuned FACT carbon shell & ultra-light rails you get a high-performance saddle thats designed to help you perform at your best. It features all of the Body Geometry design characteristics you know & love so you can be assured of superior all-day comfort for your unique position. Patented Body Geometry design is lab-tested to ensure blood flow to sensitive arteries. Mirror technology utilizes 3D printing from liquid polymer to create a one-of-a-kind honeycomb structure that offers superior sit-bone support & comfort. FACT carbon fiber shell is flex-tuned for support & ride compliance. Ultra-light oversized FACT carbon rails. SWAT™-compatible mounts molded into the saddle base allow for sleek & integrated storage solutions. NOTE: Oversized 7x 9mm carbon rails are not compatible with seatposts equipped with side-load clamp mechanisms for 7mm round rails. Size 143mm / Weight 190g Size 155mm / Weight: 194g
