Our pro-favorite S-Works Romin EVO with Mirror saddle is designed to deliver exceptional comfort and ensure blood flow to soft tissue when riding in a low, aero position. By replacing foam with our Mirror technology, we&&';;ve also reduced sit bone pressure up to 26%. 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 Body Geometry ergonomic supportive cut-out is designed to maximize blood flow, while the unique saddle shape allows you to maintain comfort, even in a competitive, aerodynamic position. Our very first concave FACT carbon fiber shell enabled us to create our thickest Mirror pad ever with 22,200 struts and 10,700 nodes, while oversized carbon rails create a saddle that&';s ready for anything.The carbon-railed, lightweight S-Works Romin EVO with Mirror is a high-performance saddle that&';s designed to put you in a position for optimal power transfer and comfort as you put pressure on your competition. Patented Body Geometry design is lab-tested to ensure improved comfort and blood flow to sensitive arteries. Mirror technology pad features 22,200 struts and 10,700 nodes, all individually tuned. Concave FACT carbon fiber shell is flex-tuned for support and ride compliance. Ultra-light oversized FACT carbon rails.
