Burgtec E-Bike Chainring

E-bike motors generate significantly higher torque than traditional drivetrains, which accelerates wear on softer aluminum rings. Steel is much harder and more durable, meaning it will last significantly longer under the constant load of an electric motor.

This chainring is designed for 104mm BCD (Bolt Circle Diameter) cranksets and is intended for an inside fit. Please confirm your crankset uses this specific 4-bolt pattern before purchasing.

The alternating thick and thin teeth are machined to match the inner links of your chain perfectly. This creates a tighter, more secure interface that prevents the chain from dropping, even when riding over rough, technical terrain.

This chainring is optimized for modern single-ring drivetrains. While it works with most standard mountain bike chains, it is best paired with a drivetrain setup that matches the 34t tooth count for optimal gear range.

Because of the specialized thick-thin tooth profile, a chain guide is generally not required for most trail riding. The profile is designed to retain the chain securely on its own, though aggressive downhill riders may still choose to run a guide for extra security.
