Burgtec Inside Fit E-Bike Chainring

E-bikes generate significantly higher torque than standard mountain bikes, which accelerates wear on softer alloy chainrings. Steel is much harder and more durable, meaning it will last significantly longer and maintain its tooth profile under the constant, heavy power output of an electric motor.

This chainring is designed for a standard 104mm BCD (Bolt Circle Diameter) mounting pattern. You should verify that your current crankset uses this 4-bolt 104mm configuration before purchasing.

The thick-thin profile is engineered to lock the chain securely onto the teeth. This design drastically reduces the chance of the chain dropping, even when you are riding over rough, technical terrain or under high power.

This is a 32-tooth, round chainring designed for 104mm BCD setups. While it is built for the high-torque demands of e-bikes, you must ensure your specific chain and drivetrain system are compatible with a 32T ring and that your crankset supports the 104mm BCD standard.

The tooth profile is specifically shaped to shed mud and debris efficiently as the chain rotates. This helps maintain consistent contact between the chain and the ring, preventing the skipping or slipping that often occurs when mud builds up in the drivetrain.
