Asymmetric Carbon 29er MTB Rim, 23mm Height, 30mm Inner Width, 300–380g, Hooked Bead for XC and All-Mountain

When the trail tightens and every gram matters on climbs, this asymmetric carbon 29er rim balances low rotational weight with the tyre volume needed for confident cornering and traction. It’s engineered for riders who alternate between race-day cross-country efforts and technical all-mountain descents, supporting modern tyre sizes and tubeless setups.

Asymmetric Carbon 29er MTB Rim - Designed for XC and All-Mountain

The 23 mm rim height keeps rotational inertia low for quicker acceleration and nimble handling, while a 30 mm inner width accommodates high-volume tyres (roughly 2.2–2.6 in) at recommended pressures. Available in three weight tiers—Standard (380 ± 15 g), Superlight (330 ± 10 g), and Ultralight (300 ± 10 g)—this hooked U-shape rim is compatible with clincher and tubeless-ready tyres when built with tubeless tape and valves.

The asymmetric left 5° / right 7° offset corrects spoke-tension imbalance on driven rear wheels, improving wheel symmetry and fatigue life when built with an asymmetric-aware lacing pattern. Structural tolerances and strength figures are specified for dependable performance under typical XC and trail loads.

Why it fits your routine

• Wide tyre support: 30 mm inner width is matched to 2.2–2.6 in tyres for improved traction, comfort, and rollover on mixed terrain.
• Low rotational weight options: Choose Standard, Superlight, or Ultralight tiers to prioritise durability or climbing performance according to your riding style.
• Trail-ready strength: Forward compressive strength >300 kg and lateral torsion resistance >50 kg suit riders up to the 100 kg limit stated for this rim.
• Tubeless-ready hooked bead: U-shape hooked bead plus a 6.5 mm valve hole supports tubeless builds with appropriate tape and valves.
• Precision tolerances: Dynamic imbalance <3 g, flatness <0.15 mm, and roundness <0.3 mm for predictable wheel behaviour and consistent truing.
• Customisable assembly: Valve hole, spoke hole, and assembly hole diameters and nipple angles can be tailored to your wheelbuilder’s specification.

Suitable riding uses include cross-country racing with the Ultralight tier for weight savings, and trail or all-mountain duty with Standard or Superlight choices to balance durability and performance, while riders heavier than 100 kg should consider a more reinforced, higher-volume rim profile.
