Shimano STEPS SM-CRE80-B Chainring | 104 BCD | 1x11/10-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.

Shimano STEPS front chainrings are designed for electric bikes (e-bikes) using a Shimano STEPS motor system. They help ensure stable and reliable chain performance when pedal power is supported by the motor, even on rough surfaces or off-road terrain.
STEPS front chainrings are compatible with Shimano STEPS motor and drivetrain systems, including versions made for 9-, 10-, 11- or 12-speed e-bike drivetrains.
No – Shimano STEPS chainrings are specifically made for Shimano STEPS e-bike systems and must match the STEPS motor crankset type and the correct chain specification.
STEPS chainrings are optimised for the higher loads of e-bike use and typically feature a more robust construction and a tooth profile designed to keep the chain secure under motor-assisted pedalling.
When choosing a Shimano STEPS chainring, it’s important to check your STEPS motor model, drivetrain speed, and the correct mounting standard (bolt circle / direct mount) to ensure full compatibility and smooth drivetrain performance.
