Shimano CS-HG200-7-Spd Cassette 14-32
This is your standard entry level cassette made by Shimano. If your upgrading or replacing your cassette it may be a good time to think about a few extra teeth on the largest cog. Most cassettes & freewheels have a 28T low cog. The 32T low cog on this cassette will make those hills just that much easier.
If you’re replacing your cassette because of wear, you should replace you chain too. That will also cover the few extra links the extra cog size will require. You may get away with your existing chain but its best to replace the chain to mesh with the new teeth of the cassette.
A good quality cassette at a great price.
