Mavic Ksyrium Hooked RB Rear Rim | Performance & Durability for Road CyclingElevate your road cycling experience with the Mavic Ksyrium Hooked RB Rear Rim, a benchmark for lightweight performance and unwavering reliability. Engineered for the discerning cyclist who demands a perfect balance of responsiveness for climbing and durability for long, demanding rides, this rim is the heart of one of the most trusted wheel systems in cycling. It represents a significant upgrade for any rim brake road bike, delivering modern technology and a tangible improvement in ride quality and confidence.The Ksyrium rim is designed to be your dependable partner on every road, from smooth tarmac to challenging backroads. Its construction focuses on creating a strong, stiff, and lightweight structure that translates every watt of your effort into forward motion. Experience more precise handling in corners, snappier acceleration, and the assurance that your equipment is built to last, season after season.Key Benefits:* Superior Strength and Stiffness: Featuring Mavic´s innovative Fore drilling technology, the upper rim bridge remains unpierced. This significantly increases the rim´s rigidity and strength where it matters most, eliminating a common weak point and ensuring better power transfer and a more robust wheel build.* Optimized Tubeless Performance: Embrace the future of road cycling with UST Tubeless technology. The seamless inner rim profile, free from spoke holes, makes tubeless tire installation incredibly simple and reliable without the need for rim tape. This system allows you to run lower tire pressures for enhanced comfort, improved grip, and significantly reduced risk of pinch flats.* Powerful and Consistent Braking: Specifically designed for rim brake bicycles, the Ksyrium RB rim incorporates the UB Control (Usiné Brut Control) braking surface. This precisely CNC-machined surface improves braking friction and eliminates shuddering, providing smooth, powerful, and predictable stopping power in all weather conditions.* Enhanced Durability and Wheel Balance: The SUP (Soudé Usiné Process) creates an extremely strong, arc-welded rim joint that is then milled for a smooth, perfectly balanced finish. This meticulous process eliminates braking judder and ensures superior wheel stability and longevity.Main Features:This high-performance rear rim is packed with Mavic´s signature technologies. The hooked rim profile ensures maximum compatibility, allowing you to securely mount a wide range of both tubeless and traditional tube-type (clincher) tires. The Fore drilling technology not only boosts strength but also saves weight by eliminating the need for a traditional rim tape, making for a lighter and more efficient tubeless setup. The entire design is optimized to create a responsive and lively ride feel, making it the ideal foundation for a high-performance, all-around rear wheel for training, racing, or epic Gran Fondos.Technical Specifications:* Discipline: Road Cycling* Brake Type: Rim Brake* Rim Type: Hooked / Clincher* Tire Compatibility: UST Tubeless and Tubetype* ETRTO Size: 622x19TC Road* Internal Rim Width: 19 mm* Rim Height: 22 mm* Valve Hole Diameter: 6.5 mm* Braking Surface: UB Control* Recommended Spoke Count (Rear): 24* Recommended Tire Sizes: 25 mm to 32 mm* Key Technologies: Fore tapeless tubeless, SUP welding, UB ControlAttributes: Road Cycling, Wheel rims
