Round AERO Thread Mount 0mm MTB

Precision engineered for performance and reliability, the ALUGEAR Thread Mount Chainring offers an exceptional blend of durability, lightweight design, and superior chain control. Designed with our signature narrow-wide tooth profile, each chainring ensures stable chain retention even in muddy or demanding off-road conditions. The self-cleaning tooth design prevents buildup and enhances long-term performance on drivetrains.

CNC-machined from aerospace-grade 7075-T6 aluminum and finished with a hard coat industrial anodizing process, the ALUGEAR Thread chainrings deliver long-lasting performance, sharp aesthetics, and a satisfying tactile feel. The threaded mount interface reduces overall weight while maintaining rock-solid reliability, making it a top choice for serious riders.

Available in sizes 30T to 40T, this range allows for precise drivetrain tuning. Whether you're building a lightweight XC rig or preparing for long-distance mountain marathons. The 30T version is a standout: perfect for riders with smaller power outputs, such as youth or women, and ideal for use with power meters where low gearing is essential.

If you're looking for a chainring that combines cutting-edge engineering, distinctive design, and light weight, ALUGEAR delivers - without compromise.

We do not offer an Oval version of this chainring. The specific Power Meter this chainring is designed for is not optimized to work accurately with oval chainrings. Using an oval chainring with this type of power meter may result in inaccurate power readings, including incorrect peaks and averaged values. For riders who rely on precise training data, a round chainring is the best choice.
