Technical Specifications

Compatibility & Fitment

This chainring fits cranks with a 5×130mm BCD and is intended for 7-speed setups using 3/32" chains. To ensure compatibility, please verify fitment before purchase: contact our Customer Support with your e-bike model, production year and batch number. Contact Onemile Support to confirm that this chainring is correct for your bike.

Installation & Maintenance

• No installation service included. Make sure you have the required mechanical skills or arrange professional installation.
• When installing, inspect chainline and front-derailleur capacity — a 52T large ring requires a front derailleur that can clear the larger diameter.
• Use proper chainring bolts and torque values as recommended by your crank/bolt manufacturer. Typical chainring bolt torque ranges are often in the ~8–12 N·m range but refer to your crankmaker's specification.
• Periodically check bolts for correct torque and inspect steel teeth for wear. Steel teeth offer improved wear resistance but will still require routine inspection.
