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)

In terms of both comfort and performance, anywhere that your body touches the bike is of the utmost importance. That's why Specialized designed the S-Works Hover Carbon Handlebars to excel on both fronts. Starting with the construction, they're made from their FACT carbon fiber for a light overall weight, vibration absorption, and high rigidity. And for comfort, much of it boils down to fit. Along these lines, they feature a shallow drop and bend that's extremely comfortable, while they also offer a 15mm rise to help accommodate a wide fit range. - FACT carbon construction offers an optimized blend of durability and light overall weight. - 15mm rise for additional rider fit range. - Shallow Bend Drop: 123mm Drop x 75mm Reach

We’re redefining comfort and 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 and develop a next-generation technology. The S-Works Romin EVO Saddle with Mirror is the future. We developed Mirror technology by 3D printing from 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 16,000 struts and 7,799 nodes, each of which can be tuned individually. And when you combine this technology with our extremely lightweight S-Works Romin EVO saddle, with its flex-tuned FACT carbon shell and ultra-light rails, you get a high-performance saddle that's designed to help you perform at your best. It features all of the Body Geometry design characteristics you know and love, so you can be assured of superior, all-day comfort for your unique position. - Patented Body Geometry design is lab-tested for both men and women to assure blood flow to sensitive arteries. - Mirror technology utilizes 3D printing from liquid polymer to create a one-of-kind honeycomb structure that offers superior sit-bone support and comfort. - FACT carbon fiber shell is flex-tuned for support and ride compliance. - Ultra-light, strong, and oversized FACT carbon rails. - SWAT-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions. - NOTE: Oversized 7x9mm carbon rails are not compatible with seatposts equipped with side-load clamp mechanisms for 7mm round rails.

This one takes all your trail dreams, from XC to enduro, all the way to eleven. SRAM's XX1 rear derailleur packs a massive amount of technology into its compact, lightweight body. It uses a “horizontal parallelogram” design that limits all movement to the horizontal axis, reducing the force it takes to shift. The Type 2 clutch is brilliant. This self-lubricating, one-way roller clutch controls your chain tension to eliminate chain slap and give you smooth, consistent shifts over any terrain. For quicker, smoother, more exact shifting, the large upper pulley's offset design maintains a consistent chain gap across all gears.

Mass is the enemy of performance, so we pulled out all the stops to make the Alpinist Seatpost the lightest post we've ever seen that passes our standards. At 136 grams (27.2mm x 300mm), it's about as light as you'll find. Not only does light weight make for faster climbing, it also improves acceleration and ride quality.
