SRAM's X0 shifters are an absolute must for riders who desire and deserve the best. The adjustable clamp mount and trigger lever allow you to custom tune the shifters for one-finger, ergonomic gear changes that are near telepathic. Crafted with a compact aluminum body and super-smooth ball-bearing pivots, the X0s are super light and race-ready, yet built tough to handle all your off-road endeavors.

SRAM's XX1 Crankset gives you less — that adds up to more! Paired with SRAM's 11-speed XX1-specific cassette (sold separately), you get the gearing of a 2- or 3-ring system, with less gear redundancy, less weight, and no front derailleur or chainguide. There's also less clutter on your bars and less chain noise. The cranks themselves are seriously light, too, thanks to carbon arms and a forged spider. But wait! There's less! Dropped chains are a distant memory. The teeth on the ingenious X-Sync rings are shaped to hold onto your chain. With XX1 cranks, less truly is more.

True competitors are always looking for a performance advantage—a relentless pursuit of equipment that is lighter, stiffer and stronger. To create the best drivetrain possible, SRAM started with a completely reengineered crankset design. SRAM's XX1 Eagle crankset is the lightest, stiffest and strongest on the market. A special hollow internal architecture, combined with SRAM's proprietary CARBON TUNED lay-up, allows us to build a lightweight and ultra-energy-efficient crankset perfectly suited for the high-wattage output and smooth style of cross country riding and racing. Teamed up with their Eagle direct mount chainring, and as an integral part of the Eagle drivetrain, the XX1 Eagle crankset puts more focused power into every ride.

Contact points—those spots where our bodies meet our bikes—are crucial areas for comfort and control. Get it wrong, and even the best bikes can be miserable to ride. We developed the new Terra handlebar to be the paragon of comfort, control, and performance, with an optimized blend of carbon fiber and advanced construction techniques yielding exceptional ride comfort, precise handling, and class-leading strength at an impressively low weight. A shallow drop and moderate reach combine with a 12-degree flare for optimal all-terrain comfort and control. - Optimized blend of high modulus carbon fiber materials and advanced construction techniques yield a light and confident bar - Ergonomic top perch alleviates pressure on the hands - Bar flared 12 degrees at the drops for added stability - Bend: 103mm drop x 70mm reach

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

Competition-focused technology is available to everyone with SRAM's Force Crankset. Its unidirectional carbon design and integrated bottom-bracket axle ensure top-notch stiffness for awesome power transfer and exceptional lightness. And, because being light is nothing without being tough, the Force proudly boasts SRAM's hard-anodized PowerGlide chainrings for long-lasting durability and lightning-quick shifts.

The Specialized Power Arc Pro saddle expands on the success of their original Power saddle. It features the same channel and length as the original and S-Works Arc, but where it differs is in its titanium rails vs. the carbon fiber found on the S-Works. But this means that it still features a stiff, FACT carbon fiber shell and lightweight EVA padding. The shape of the saddle is also designed to provide ample sit bone support, and this has been coupled with a shorter-than-usual nose section to keep pressure off of soft tissue while riding in aggressive positions. Specialized even took this ideology a step further via an extra wide and elongated Body Geometry channel that's been proven through blood flow testing and pressure mapping to reduce numbness and pressure on unwanted areas. While this all seems familiar if you're already a Power loyalist, this iteration features a curved Body Geometry shape that better contours to your body. What does this mean for your ride? It means that you'll feel as if you're “in the saddle," not on it. And ultimately, this equates to greater comfort and superior performance in all seated positions, whether you're a man or woman. - Patented Body Geometry design is lab tested for both men and women to assure blood flow to sensitive arteries. - Stiff FACT carbon fiber shell is tuned for support and ride compliance. - Super-light EVA padding for comfort and support on longer rides. - Lightweight, durable, and hollow titanium rails. - Level 2 padding: Medium density foam for bike feel with additional cushioning. - SWAT-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions. - Size 143mm / Weight: 193g - Size 155mm / Weight: 199g
