* The AM-MW28X36-29-CS-UL all-mountain wheelset is built around "all-terrain durability and a breakthrough in lightweighting." Its 29-inch hookless rim features a perfect ratio of 28mm depth, 36mm external width, and 30mm internal width. Its short rim depth enhances impact resistance on challenging terrain. * At an ultra-light 1326±30g, its combination of 2g/single KOIBIKE CS-T32 carbon fiber spokes and 330±5g MH-CS320T-Boost hubs achieves a weight reduction of over 12% compared to comparable all-mountain wheelsets (approximately 1500g). *Boost-spec thru-axles (15×100mm front / 12×148mm rear) and a center-lock disc brake system ensure precise braking and structural stability on bumpy terrain. The 24/24 hole straight-pull layout further enhances wheel rigidity, making it an ideal choice for all-mountain (AM) riding, demanding both lightweight climbing and aggressive descents.

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.
