With Mirror Technology, we are redefining comfort and performance and bringing Body Geometry into the future. The last major material innovation in saddle design occurred decades ago with the introduction of foam. To advance the evolution of saddles, we needed to think outside the box to create something entirely new. The S-Works Romin EVO with Mirror Technology is a glimpse into the future. Using 3D printing with liquid polymer, Mirror Technology perfectly reflects the anatomy of the rider. This revolutionary process creates a complex honeycomb structure that allows us to adjust the material density continuously—something that would be impossible with foam. The result is a patented matrix of 22,000 branches and 10,700 nodes, each of which can be individually tuned. When this technology is combined with our extremely lightweight S-Works Romin EVO, featuring a FACT carbon shell and ultra-light saddle rails, you get a high-performance saddle that helps you achieve your best. It includes the well-known Body Geometry design features, allowing you to pedal all day with superior comfort. The patented Body Geometry design has been lab-tested to ensure arterial blood flow. Mirror Technology utilizes 3D printing with liquid polymer to create a unique honeycomb structure that provides superior sit bone support and comfort. The flex of the FACT carbon shell is tuned for optimal support and compliance. Ultra-light oversized FACT carbon saddle rails. SWAT-compatible mounts integrated into the saddle shell allow for sleek and seamless transport of accessories. Note: Oversized 7x9 mm carbon saddle rails are not compatible with seat posts that use a side clamp mechanism for round 7 mm saddle rails. Size 143 mm / Weight 190 g.
