Shimano STEPS SM-CRE80-12-B Chainring | 53mm Chainline | 104 BCD | 1x12-speed

Shimano STEPS chainrings

Shimano STEPS chainrings are designed for electric bike (e-bike) drivetrains using Shimano STEPS motors and cranksets. They are replaceable components built to match different STEPS systems – from city/trekking e-bikes to e-MTB setups – ensuring proper chain engagement and smooth interaction between the motor and drivetrain. STEPS chainrings are available in multiple tooth sizes and configurations to suit different chainlines, gear systems and riding styles, while maintaining reliable chain performance on e-bikes.

Features:

• Purpose: designed for use with Shimano STEPS e-bike systems.
• Compatibility: different versions are compatible with 9-, 10- and 11-speed drivetrains (depending on the model and chain type).
• Mounting standards: most commonly fitted to motor cranksets using a 104 mm BCD mounting standard.
• Tooth size options: available in several tooth counts (e.g., 34T, 36T, 38T and 47T), allowing you to match gearing to your riding style and gear range.
• Chainline fit: models are designed for different chainline widths (e.g., 50 mm, 53 mm, 55 mm) to match specific e-bike configurations.
• Materials and profiles: typically made from steel or aluminium with a tooth profile optimised for chain retention and smooth pedalling.
• STEPS motor compatibility: compatible with many Shimano STEPS series cranksets (e.g., E6000, E6100, E8000, EP8), depending on the model and tooth count.
