Does this mean the Kicker Core is a no-go entirely, or would I just need to buy additional parts for the bike, the trainer, or both? I have no experience with trainers, so bear with me if this is a dumb question.
That my friend is a freewheel not a cassette:

You could purchase a 7 speed cassette to work but I gotta wonder what kind of bike she is running? 7 speed freewheels are long out of date so it is either something cool and vintage or she could use something a little nicer not from Aisle 10 at WallyMart and you could get a cheaper trainer. Either way check and make sure the spacing will work on that as it is possible the bike could still be 126 spaced (not likely in 7 speed but you never know)
