To determine if a sprocket is a freewheel or cassette system, remove the rear wheel from the bike. Find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fittings spin with the cogs, it is a cassette system with a freehub.
How do I know what cassette is on my bike?
The number of cogs determines the type of chain (10 cogs = 10-speed chain) and of course the type of cassette you’ll want to order. (in our case a ten-speed) The two teeth counts tell you which cassette you’ll need. In our case it would be an 11-42 cassette. Don’t forget to check the front chainrings for wear.

Are all Shimano cassettes compatible?
Compatibility between different drivetrains
SRAM and Shimano cassettes, on either road or mountain bike, are interchangeable with each other as the spacing is the same between the sprockets.
What is the difference between a freewheel and cassette hub?
What is the main difference between freewheel and cassette hub? The freewheel is a single-unit and the act of pedaling tightens the freewheel to the hub. Whereas the cassette hub is a set of gears (cogs) that slides onto a cassette and is held in place by a lock ring.
