Burgtec E-Bike Chainring

Electric mountain bikes generate significantly higher torque loads than standard bikes, which wears down aluminum teeth much faster. Steel is substantially harder and more durable, meaning this chainring will last significantly longer and resist deformation under the constant power of an e-bike motor.

This chainring is compatible with 4x94mm or 4x104mm bolt patterns. You should verify your current crankset's BCD (Bolt Circle Diameter) before purchasing to ensure a proper fit.

The narrow-wide tooth profile is designed to interlock precisely with your chain's inner and outer links. This creates a secure fit that drastically reduces the chance of your chain dropping, even when you are riding over rough, technical terrain.

The chainring features specific machining that prevents mud and debris from packing into the teeth. By keeping the interface between the chain and the ring clear, you maintain consistent drivetrain efficiency and prevent skipping, even in wet or sloppy trail conditions.

While the narrow-wide profile is highly effective, you should ensure your chain is compatible with the specific width of these teeth. It is designed for standard e-bike drivetrain setups, but always check your chain manufacturer's specifications if you are running a non-standard or ultra-narrow chain.
