The MTN E-Ring is a cold-forged, surface-hardened chainring made from high-quality steel, specifically designed for e-MTB use and long service life. It features a 104 mm BCD and a Narrow-Wide tooth profile for secure chain retention on 1× drivetrain systems.

Important: Before purchasing, make sure that the crank spider uses a 104 BCD standard and not the smaller 94 BCD design.
Important Notes
A clutch-equipped rear derailleur is mandatory, such as Shimano Shadow or SRAM Type 2.
For rough terrain or maximum chain retention, the use of an upper chain guide is recommended.
Threaded design: the MTN E-Ring has an internal thread and must be installed using a standard M8 external-thread chainring bolt.
During installation, the logos must face outward.
Follow the installation orientation shown in the product images.
