Carbon Mtb Rim

High-Grade Carbon Fiber: Lightweight yet ultra-durable, built to handle rough off-road terrain. Offset Spoke Holes: Balances spoke tension for enhanced stability during turns and impacts. 25mmx35mm Dimensions: 35mm width supports 2.1-2.6" tires for better grip; 25mm height blends strength and lightness. Straight Sidewall: Secure tire retention (even at low pressure) and easy maintenance. Customizable: Factory-tailored options (spoke holes, colors, etc.) for personal needs. Off-Road Focus: Perfect for mountain biking—enduro, trails, and tough landscapes.

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.

The XC-M30X34HL-29ER-UL all-mountain rims, with their optimal 30mm height and 34mm outer width, strike a precise balance between lightweight and drivability. The 29-inch wheel diameter and ultra-light weight of 350 ± 15 grams are nearly 15% lighter than comparable rims, delivering even more explosive off-road riding. The hookless straight-edge design accommodates tires from 2.1-2.5 inches, and the tire pressure range of 19-27 provides flexible handling across diverse terrains. The UD/Marble/12K/12K twill finish offers both a premium look and scratch resistance. Available in both all-mountain and cross-country versions, these rims offer tailored performance for diverse riding scenarios, redefining the efficiency and reliability of off-road rims.

The XC-M25X30HL-29ER-UL is KOIBIKE's structural innovation for the next-generation, lightweight, wide-body XC/Trail platform. Its low 25mm frame height maintains lateral stiffness while achieving extremely low rotational mass. Its 30mm external width reshapes the support structure for tires 1.9–2.35 inches, improving tire tension consistency and contact patch. Weighing a mere 260±15g per rim, its high-modulus Toray carbon fiber allows the bike to handle challenging terrain. It supports tire pressures from 21–32 psi and is tubeless compatible, improving impact resistance and grip at low tire pressures. Its matte UD finish blends industrial texture with environmental adaptability, making it the ultimate choice for those pursuing the "light yet not bulky, wide yet not stagnant" riding philosophy.
