Asymmetric Carbon 27.5 MTB Rim | 30mm Inner, Ultralight, Tubeless

Asymmetric Carbon 27.5" MTB Rim – 30mm Inner Width, Tubeless-Ready

Direct answer: This asymmetric carbon 27.5 MTB rim features a 30mm inner width and supports both standard (435g) and superlight (370g) build grades. It is optimized for 2.3"–2.6" mountain and 33–40mm cyclocross tire compatibility, all-mountain/enduro conditions, and is designed for tubeless setups. Why asymmetric design? The offset spoke bed equalizes tension (nipple angle L5°/R7°), increasing lateral stiffness and wheel durability, especially under heavy torque loads. 3-year manufacturer warranty applies.
