MAVIC Ksyrium UST Rear Rim | Road Cycling Performance & RepairRevitalize your dependable wheelset with the official MAVIC Ksyrium UST Rear Rim. This is the authentic replacement rim to swap out a damaged one and repair your MAVIC wheel, ensuring you regain the renowned performance and reliability you expect from the brand. Engineered for dedicated road cyclists seeking an optimal balance of light weight, durability, and riding comfort, this rim incorporates Mavic´s most advanced engineering to restore your bike to its prime condition.Discover the significant advantages of a perfectly refurbished wheel. The Ksyrium UST rim is designed to provide a more dynamic and comfortable ride. By replacing a damaged rim, you not only enhance your safety but also recover the swift acceleration and precise handling for which the Ksyrium range is known. It´s the ideal solution for extending the lifespan of your premium MAVIC wheels following an accident or considerable wear, presenting a wise and cost-effective alternative to purchasing an entirely new wheelset.Achieve Exceptional Performance with Key TechnologiesThe MAVIC Ksyrium UST Rear Rim features numerous innovations aimed at improving every aspect of your road cycling experience.* Simplified Tubeless Setup (UST): Mavic´s Universal System Tubeless (UST) technology makes operating a tubeless system more straightforward and secure than ever before. The unique rim bed profile facilitates easy tire installation and inflation, while ensuring a tight seal for running at lower tire pressures. This leads to considerably reduced rolling resistance, a smoother and more comfortable ride, and a diminished risk of pinch flats.* Lightweight Agility (ISM 4D): Utilizing Inter Spoke Milling 4D (ISM 4D), material is selectively removed from the rim between the spoke holes. This proprietary process significantly reduces weight and rotational inertia without compromising structural integrity or longevity. The outcome is a wheel that ascends more rapidly, accelerates quicker, and feels exceptionally responsive on the road.* Superior Strength and Rigidity (Fore Drilling): Instead of drilling through both sides of the rim, Fore technology directly threads the spoke nipples into the lower rim bridge. This leaves the upper rim bridge intact, resulting in enhanced strength, increased stiffness, and a completely airtight seal. A major benefit of this design is the elimination of rim tape, saving weight and removing a common failure point in tubeless configurations.* Seamless Rim Joint (SUP): The Soudé Usiné Process (SUP) creates an exceptionally strong, arc-welded rim joint. Following welding, the joint is precisely milled to achieve a smooth, imperceptible finish. This not only strengthens the wheel´s structure and improves its balance but also provides a clean, vibration-free braking surface for superior stopping power.---Characteristics:Airflow Guides:- The design incorporates blades that create a smooth transition between the wheel and tire, guiding airflow around them. This reduction in turbulence where the tire meets the rim further minimizes aerodynamic drag.CX01 Technology Specific:- Specifically engineered for rims and tires featuring CX01 technology, such as Cosmic CXR rims and Yksion CXR tires.---Technical Specifications* Classification: Rims, Road Cycling* Construction Material: Maxtal Aluminum Alloy* Brake Type Compatibility: Rim Brake* Incorporated Technologies: UST Tubeless Ready, ISM 4D, Fore Drilling, SUP* ETRTO Dimension: 622x19TC Road* Drilling Method: Fore (eliminates the need for rim tape in tubeless setups)* Braking Surface Treatment: UB Control (Usiné Brut Control) for improved braking friction* Tire Compatibility: Suitable for both UST Tubeless and standard Tubetype tires* Recommended Tire Size Range: 25mm to 32mm* Valve Stem Hole Diameter: 6.5 mm
