ethirteen e*spec Direct Mount Chainring Info

e*spec Direct Mount Chainring is designed to meet the unique demands of modern e-MTB drivetrains, delivering reliable chain retention and efficient power transfer under high torque loads. Built as part of e*thirteen’s e*spec lineup, this direct mount chainring offers a clean, integrated fit for compatible e-bike crank systems.

At the core of the design is e*thirteen’s M3 narrow-wide tooth profile, engineered to reduce overall weight while maintaining secure chain engagement on rough terrain. This profile is optimized for the constant load and higher chain forces generated by e-bike motors, helping keep the drivetrain quiet and stable during hard accelerations and technical climbs.

The steel version serves as a direct OEM-style replacement, offering excellent durability for riders who prioritize longevity and reliability. For those looking to upgrade, the aluminum versions provide a lighter-weight option with refined aesthetics and strong wear characteristics, making them a smart choice when replacing an original equipment chainring.

This e*spec Direct Mount Chainring is a discontinued model, making it a strong value option for riders seeking proven e-bike performance at a reduced price point. Compatibility and sizing availability vary by motor system, so it’s best suited for riders who already know their required specification.
