29er Asymmetric Carbon MTB Rim | 30mm Height, 30mm Inner Width | Freeride & Enduro

29er Asymmetric Carbon Freeride Rim: Performance Meets Durability

A high-performance asymmetric carbon fiber mountain bike rim engineered for 29-inch freeride, enduro, and aggressive trail applications. Available in standard (455 ±10g) and superlight (385 ±10g) layups, with a 30mm inner width optimized for 2.3–2.6" tires and a U-shaped profile that balances lateral stiffness with vertical compliance.

Key Specifications

Why Asymmetric Design?

The asymmetric spoke-bed offset redistributes spoke tension more evenly between drive-side and non-drive-side spokes. On a standard symmetric rim, drive-side spokes carry significantly higher tension, accelerating fatigue and increasing the risk of spoke breakage on high-torque trail riding. The asymmetric geometry reduces this imbalance, improving wheel durability and long-term trueness under load — a measurable advantage for freeride and enduro disciplines where repeated hard landings are the norm.

30mm Inner Width: Use-Case Context

A 30mm internal width is optimized for 2.3–2.5" MTB tires, providing a stable casing base that reduces sidewall squirm under hard cornering. Compared to a narrower 25mm rim, the wider bed lowers the effective tire pressure needed for traction while maintaining casing integrity. Note: Riders using tires wider than 2.6" may benefit from a 35mm inner width rim; contact us to discuss the right option for your build.

Quality & Warranty

Manufactured under ISO-compliant production processes with over a decade of supply experience to cycling brands in Europe and North America. Every rim undergoes dynamic equilibrium testing (<3g tolerance) and flatness verification (<0.15mm) before dispatch. Backed by a 3-year warranty against manufacturing defects.

Frequently Asked Questions

Is this rim tubeless-compatible?

The hookless U-shape profile is designed for tubeless-ready (TR) tire systems. Ensure your tire is rated for hookless rims and does not exceed 65 psi maximum inflation pressure.

What tire width works best with a 30mm inner width rim?

This rim is optimized for 2.3–2.6" MTB tires. A 30mm inner width provides an ETRTO-compliant mounting base for this tire range, balancing sidewall support and volume.

How does 385g compare to other lightweight 29er carbon MTB rims?

The superlight layup at 385 ±10g places this rim in the competitive range for carbon 29er enduro rims, which typically span 360–430g depending on width and height profile.

Can I use this rim for aggressive freeride or jump riding?

Yes. The forward compressive strength (>300kg) and spoke hole tension resistance (>280kg) are rated for the high-impact loads associated with freeride and jump disciplines, within the 100kg rider weight limit.

Is OEM or private label available?

Yes. We supply small to medium cycling brands and professional teams with OEM and private-label options. Contact us to discuss minimum order quantities and customization scope.
