Product Details

Dialed for strength, precision, and clean chain retention. The COIL DM chainring is forged and CNC-machined to perfection, built around SRAM’s 3-bolt direct mount system and ready for everything from standard to Boost setups.

Identity: For riders who need reliability at the core of their drivetrain — downhill, enduro, trail, or bikepark laps. A narrow-wide profile keeps the chain locked, while multiple offsets and tooth counts give you the freedom to fine-tune. Pro-level performance, but accessible to anyone stepping up their build.

Energy: Strong hold, smooth spin. Keep the power flowing.
