Our all-rounder. A 240 hub combined with a carbon rim results in a durable and versatile package. The low weight of the carbon rim, specially designed for all-mountain use, combined with the latest evolution of the 240 hub with RATCHET EXP freewheel, make the XMC 1501 SPLINE ONE wheels the perfect partner in crime for all kinds of mountain adventures. The 30mm inner width of the tubeless-optimized carbon rim provides excellent support for the wide tubeless tire. Double-butted competition race spokes and the highest quality wheel construction round off our XMC 1501 SPLINE ONE wheels.

SMOOTHER IS FASTER: Trail riders who prize nimble handling will be blown away by the category-leading control, strength-to-weight ratio, and pinch-flat resistance of Traverse SL II i9. STRONGER: Front and rear-specific rims with carbon layups optimized for strength and weight boast 15% greater front wheel strength and 25% more rear wheel strength than the previous Traverse SL. VERTICAL COMPLIANCE: The new Traverse SL II i9 1/1 is 21% more vertically compliant than the previous model (delivered through a shallow rim shape and front/rear-specific layup), which enables enhanced terrain-hugging and bump-force-absorbing control. TRAVERSE SL II i9 1/1: TRACTION MONSTER: Carefully engineered rim shape intentionally flexes for improved support and traction to boost confidence and control. TOUGH LIFE, LONG LIFE: Engineered rim offset enables balanced spoke tension for improved fatigue life. SAYONARA PINCH FLATS: Our U.S. patent pending Flat Top bead profile requires 85% more force to pinch flat compared to a standard round bead, virtually eliminating "snake bites.” AIR TIME: Thank our genius engineer, Chuck Teixeira, for inventing the “Roval ThreadBed Valve”—a valve that threads directly into the rim. This ingenious design eliminates compression nuts, air loss from rim flex, makes tire set-up easier, and reduces sealant clogs. HIGH ENGAGEMENT: The i9 1/1 hub optimizes control via a dual-phased-pawl drive mechanism, accomplishing 90 points of engagement and 4° engagement by way of a six-pawl driver and 45-tooth drivering. The result is immediate power transfer from the pedals to the drivetrain, propelling riders forward with minimum lag. Perfect for ratcheting through techy sections. LIFETIME WARRANTY: On Roval Wheels when registered within the first 90 days of purchase. CRASH REPLACEMENT: 2-Year “It Happens” No Fault Crash Replacement—If you damage your Roval product while riding within the first two years of ownership and it’s not covered under warranty, we’ll still replace or repair it. “It Happens” is market-specific, and wheels must be registered.

The S-works Power Saddle with Mirror technology is 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-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. - Size 143mm / Weight 190g - Size 155mm / Weight: 194g - NOTE: Oversized 7x9mm carbon rails are not compatible with seatposts equipped with side-load clamp mechanisms for 7mm round rails.

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. - Titanium rails. - 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. - Patented Body Geometry design is lab-tested to ensure blood flow to sensitive arteries. - SWAT™-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions. - Approximate weight: 251g (Size 155mm) - Approximate weight: 245g (Size 143mm)
