Freewheel vs. Cassette
The MF-TZ510-7 is a threaded freewheel, not a cassette.
A freewheel screws onto a compatible threaded rear hub and contains its own freewheel mechanism. A cassette mounts onto a freehub body using a different interface.
These systems are not directly interchangeable. Verify your rear hub type before ordering.
Compatibility and Installation
Designed for compatible threaded rear hubs and 7-speed shifting systems.
Check the hub mounting interface, derailleur capacity and chain compatibility before installation. Use the appropriate freewheel removal tool when replacing an existing unit.
Note: Shimano offers this model in versions with or without a spoke protector. Verify the exact package configuration before purchasing.
