The KOIBIKE FB25X65-26ER is an ultra-wide carbon fiber snow rim designed for polar expeditions and all-terrain adventures. Its 25mm rim depth and 65mm outer width, along with a redesigned tire support structure, accommodate ultra-wide snow tires from 3.2-4.5 inches, delivering a "floating" maneuverability on loose snow, sand, and ice. Each rim weighs only 600g (±15g) and is molded from high-modulus Toray carbon fiber. A variety of paint finishes, including UD, marble, 12K, and twill, are available for customization. Directly manufactured in KOIBIKE's own factory, it offers consistent quality and manageable delivery times, making it an ideal OEM/ODM choice for high-end snowmobile brands and the aftermarket.
