Most likely, it's a freewheel, but I need to know the difference, so I will know what to look for for future wheel purchases...
You will need a cassette and chain that matches your wheel, either 8,9 or 10. You should be good to go running in friction mode.
I did a similar conversion on one of my old Cannondales. Jammed in a 130 wheel, new chain and kept everything else.
I did a full brifter 10 speed conversion on a different Cannondale and my steel bike.
