What to Compare Before Buying
- Drivetrain: Confirm that your bicycle uses a 10-speed cassette.
- Freehub and component fit: The listing names an HG system and Shimano, SRAM, and Sunrace components. Check your exact freehub and drivetrain compatibility; brand names alone do not establish fit.
- Gearing: Compare both the 11-36T range and the individual sprocket sizes with the cassette you are replacing.
Before You Decide
Check the bicycle’s cassette speed, freehub compatibility, and required gear range. If the fit or installation is uncertain, consult a bicycle mechanic.
