Mtb Rims

A perfect blend of performance and personality, designed specifically for mountain off - road use.? Made with Toray high - modulus carbon fiber, each rim weighs only 265 - 345g, which is over 30% lighter than traditional aluminum alloy rims while being able to withstand severe impacts from off - road terrain.? Features a golden ratio of 25mm height and 27mm outer width, along with a straight - edge design. This not only optimizes aerodynamic performance but also enhances lateral tire support, being compatible with 2.1" - 2.75" wide tires and tubeless systems for more precise control on complex terrains.? Offers full - dimensional customization capabilities: from carbon fiber textures like 3K twill and UD unidirectional patterns, to the choice of 28 - 36 spoke holes (suitable for needs ranging from XC racing to AM all - terrain), and even laser - engraved decals, all can be customized on demand to meet the personalized expression of both professional teams and individual riders.? As a factory - direct product, it skips intermediate links, achieving higher cost - effectiveness with the same quality, making every performance investment more valuable.
