Compatibility, Size and Fit
Check that your bicycle uses a cassette rather than a threaded freewheel and is set up for a 7-speed cassette. Confirm that the hub and drivetrain are compatible with this specific model and its 11-34T range. The speed count and tooth range alone do not establish fit for a particular bike.

Confirm the CS-M40 model, cassette-versus-freewheel type and 7-speed fit. Check the 11-34T range against your bicycle’s components before selecting this cassette.
