Mtb Wheels

Strong Off-Road Adaptability: 29-inch wheel size + 35mm wide straight-side rim for easy obstacle crossing and anti-deflation; 25mm low-profile design balances light weight and impact resistance. Eccentric spoke holes ensure even force distribution for better durability. Flexible Hub Options: 15X100/12X148mm thru-axle + straight-pull structure for high rigidity and efficient power transfer. Offers a choice between ball bearings and ceramic bearings to meet different needs. Professional-Grade Components: Sapim CX-ray stainless steel spokes (low wind resistance, high tensile strength) paired with carbon fiber rim, reducing weight for easier riding while absorbing vibrations. Universal & Easy Maintenance: Fits most mountain bike frames/tires. Straight-pull spokes and user-friendly bearing structure enable simple daily maintenance.

* 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-MA25X33HL-29ER-UL is a multi-modal carbon fiber wheel developed by KOIBIKE for modern all-terrain riding. Its extra-wide 33mm outer diameter accommodates tires from 2.0 to 2.45 inches, while its low 25mm rim depth ensures lightweight and comfort. Its rim weight is 330 ± 15g per rim, achieving highly efficient quality control for a wide-body rim. Its innovative 3mm offset hub interface balances spoke tension on both sides of the wheel, enhancing structural symmetry. It supports tire pressures from 20 to 30 psi and is tubeless compatible, making it suitable for Cross-Country, All-Mountain, and Trail riding styles. Its matte UD finish blends the pristine texture of carbon fiber with its environmental durability, representing a structural evolution in high-performance off-road wheels.

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.

The XC-M25X27HL-29ER-UL is KOIBIKE's ultra-light carbon fiber rim designed for modern lightweight XC platforms. Its 25mm frame height achieves a precise balance between lateral stiffness and dynamic response, while its 27mm external width optimizes the airbag geometry for 1.8-2.2-inch tires, enhancing grip and predictable handling. Weighing a mere 285±15g per rim, the rim utilizes high-modulus Toray carbon fiber with gradient layup technology to significantly reduce rotational mass, enhancing starting agility and climbing efficiency. It supports tire pressures from 22-31psi and is tubeless compatible, improving puncture resistance on challenging trails. Its matte UD finish combines an industrial aesthetic with weather resistance, making it an ideal choice for XC riders and high-end OEMs seeking ultimate efficiency.

The EM-MA28X38HL-29ER-UL is a structurally evolved carbon rim developed by KOIBIKE specifically for endurance racing and high-intensity all-mountain riding. Its 38mm diameter accommodates tires sized 2.1- to 2.6-inch, and its 28mm structural depth provides a stable balance between lightweight and impact resistance. Weighing 490 ± 15g per rim, it utilizes high-modulus Toray carbon fiber with an impact energy dissipation ply to effectively absorb high-frequency impact forces during continuous descents, rock ledges, and jumps. The 3mm offset spoke holes optimize tension distribution and enhance the wheelset's structural consistency under asymmetric loads. It supports tire pressures from 18–30 psi and is tubeless compatible, making it suitable for modern low-pressure, wide-tire strategies. Available in four finishes: UD, marble, 12K plain, and 12K twill, it meets both performance and aesthetic needs.
