The Perfect Reflection of You. The Power Expert with Mirror saddle combines comfort and performance for riders whether they are podium-seeking crushers or everyday cruisers. The Body Geometry designed Power shape with high-tech Mirror inserts provide sit bone-friendly support road to mountain uses. ATTAINABLE TECH: The Power Expert with Mirror saddle provides riders with a significant reduction in pain-causing pressure when compared to it's foam counterpart, the Power Comp Saddle. Inside the saddle are two tear drop shaped Mirror Technology inserts that target sit bone pressure. Riders around the world will be stoked that the new Expert level Power Saddle with Mirror technology make these benefits more attainable than ever. POWER SHAPE: Our beloved Power shape, with a cutout. The patented Body Geometry design is lab-tested to ensure blood flow to sensitive arteries. Is it a road saddle? Mountain saddle? In short, yes. We hate to say a product works "for everything", but it does. We believe that performance-in saddle speak-means comfort. And whatever shape and material suits you, will be your highest performing saddle. MIRROR TECHNOLOGY: We developed Mirror technology by 3D printing from a liquid polymer to be a perfect reflection of you. Mirror technology allows for infinite density tuning with a single material, but any material is only as good as the designers and engineers that use it. Thanks to our Body Geometry methodology, Retul data, and decades of experience, the 3D-printed matrix is tuned to support the sit bones across a greater area, creating a hammock effect that lets the saddle support your weight, not the tissue around your sit bones. ANY BODY, EVERY RIDE: We know that every body is different, but the issues facing riders in the saddle are the same—sit bone pressure, scar tissue build-up, and blood flow loss. Using pressure mapping, blind comfort studies, and blood flow studies, Body Geometry and Mirror Saddles don't just promise to solve these issues for people-we've proven they do. Plus, this is the first saddle with Mirror technology in additional sizes (130 and 168). ALL AROUND USE: The Power Expert With Mirror saddle uses the same 3D printed technology as the S-Works Power with Mirror except the Expert has 4-way stretch cover to keep mud and debris out of the nooks and crannies of the Mirror lattice. That dirt-shedding feature, plus super durable, yet light weight hollow titanium rails make the Power Expert with Mirror the smart choice for gravel and mountain riders, in addition to those who stick to paved surfaces.

Mirror goes Pro. Our best-reviewed saddle technology, based on two decades of Body Geometry research and development, is now available on the Power Pro saddle. Looking beyond foam, we developed Mirror technology. By 3D printing with a liquid polymer to create an infinitely tunable honeycomb structure, Mirror saddles perfectly reflect your anatomy to keep you comfortable, powerful, and healthy in your unique position. The Power Pro with Mirror starts with our Power shape—beloved by riders worldwide for its extra-wide and elongated Body Geometry channel—and is topped with the exact same Mirror pad as our S-Works Power with Mirror, a patent-pending matrix of 14,000 struts and 7,799 nodes, each of which can be tuned individually to deliver unprecedented sit bone comfort and soft tissue protection. But our Pro-level saddle features titanium rails and a reclaimed carbon fiber base to bring Mirror technology to more riders on more terrain than ever before. The bike may be the most sustainable transportation ever created, but we need to do more. The saddle's carbon base is built with our all-new reclaimed carbon process. This is our first step on the road to closed-loop production, maximizing efficiency in production and minimizing waste. Using carbon scraps from factory production, combined with injected nylon, we're building a more sustainable carbon base. With the Power Pro's titanium rails, Mirror technology is now more durable than ever. It's so strong that our Mirror technology is now trail-ready, so go ahead and huck that gap. Trail riders have sit bones too, after all. Whether you're on the road or trail, going up or down, the Power Pro with Mirror will get you there comfortably and quickly. It's the perfect reflection of you. - 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 and comfort. - Reclaimed carbon fiber and nylon-injected base. 15% reclaimed carbon fiber. - Titanium rails. - SWAT-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions. - Approximate weight: 245g (Size 143mm) - Approximate weight: 251g (Size 155mm)

The Romin EVO Pro with Mirror starts with our Body Geometry methodology and combines this with our game-changing Mirror saddle technology to create an unmatched combination of performance and comfort. The saddle is designed for riders that prefer an agressive, performance inspired position that still protects soft tissue and blood flow. The result? 26% less pressure, right where it counts. PERFORMANCE MEETS COMFORT: The new Romin EVO Pro with Mirror saddle uses the exact same 3D printed pad as the S-Works Romin EVO Pro with Mirror but now comes with a nylon and reclaimed carbon fiber shell and hollow Ti rails. Our Romin EVO has been a favorite for our professional athletes and racers everywhere season after season. Its traditional long shape is designed to relieve pressure in aggressive, race-inspired positions while allowing the rider to slide backward and forward on the saddle to provide the ideal position for tempo climbing or maximum wattage efforts. Now with Mirror technology, the saddle reduces pressure by up to 26% compared to traditional foam saddles, validated with extensive high-resolution pressure mapping studies. It uses a 3D printed matrix with 22,200 struts and 10,700 nodes and features a unique concave shell to deliver our thickest Mirror pad yet. To ensure your fit is dialed, it comes in two widths: 155mm and 143mm. BODY GEOMETRY AND MIRROR: We know that every body is different, but the issues facing riders in the saddle are the same — sit bone pain, scar tissue build-up, and blood flow loss. Using pressure mapping, blind comfort studies, and even penile blood flow studies (yeah, we did that), Body Geometry and Mirror Saddles don’t just promise to solve these issues for men and women — we’ve proved they do. Unlike traditional single-density foam, Mirror technology allows for infinite density tuning with a single material. But any material is only as good as the designers and engineers that use it. Thanks to our Body Geometry methodology, Retül data, and decades of experience, the 3D-printed matrix is tuned to support the sit bones across a greater area, creating a hammock effect that lets the saddle support your weight, not the tissue around your sit bones. DURABILITY AND SUSTAINABILITY: By using reclaimed carbon fiber in the shell, we’re keeping scrap carbon fiber out of landfills while creating a light and durable saddle. Add to this hollow Ti rails, and you’ve got a saddle light enough for performance road and XC riding - just 243 grams in a 143 mm width — and tough enough for gravel and trail riding. - 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. - SWAT™-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions. - Lightweight and durable hollow Ti rails. - Reclaimed carbon fiber and nylon-injected base. 15% reclaimed carbon fiber. - Size 143mm / Weight: 239g - Size 155mm / Weight: 245g
