Designed for cross-country and trail riders who want lower rotational weight, improved lateral stiffness, and wheels that stay true under load. Available in a superlight 380 ± 10g variant or a standard 450 ± 15g build, with OEM customization and a 3-year warranty.\u003c\/p\u003e\n\u003ch2\u003e29er Asymmetric Carbon MTB Rim - Designed for XC and Trail Performance\u003c\/h2\u003e\n\u003cp\u003eThe rim’s asymmetric, offset spoke bed balances spoke tension for increased wheel durability and more consistent power transfer, while a 27mm internal width accommodates modern tire profiles for traction and stability. A 30mm rim profile delivers a balanced mix of lateral stiffness and compliance suitable for mixed-terrain riding, and the hookless U-shaped design is tubeless compatible for lower pressures and improved puncture resistance.\u003c\/p\u003e\n\u003cp\u003eThe lightweight Toray-grade high-modulus carbon fiber construction reduces rotational mass to improve acceleration and handling without sacrificing robustness.
