Miranda ChainFlow 38T Chainring for Yamaha PW-X3/PW-S3

Miranda ChainFlow 38T Chainring: Smoother Shifting for Yamaha Motors

Made from sturdy steel and weighing just 315 grams, it’s a direct fit for Yamaha PW-X3 and PW-S3 mid-drive motors. The included protective edge can be unscrewed easily if you prefer a lighter, minimalist setup.

Is this chainring compatible with my e-bike?

This chainring is specifically designed for Yamaha PW-X3 and PW-S3 mid-drive motor systems. It works with derailleur drivetrains up to 11 speeds when combined with a single front chainring. Check your bike’s motor model before ordering to ensure a proper fit.

What does the ChainFlow profile actually do?

ChainFlow uses a taller tooth profile than a standard chainring, which helps keep the chain engaged on the ring while shifting gears. This reduces the chance of the chain slipping or dropping off, giving you smoother, more confident gear changes, especially under the higher torque of an e-bike motor.

Can I remove the protective edge if I don’t need it?

Yes, the protective rim on this chainring is designed to be unscrewed easily if you don’t need it or prefer a cleaner, lighter look. This gives you flexibility to customize the chainring to your riding style and setup without affecting its core performance.
