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.
