What you have is not a cassette,it is a freewheel. There will not be enough space for a freewheel with any more speeds on your current wheel. To get more speeds you would have to buy a new wheel and you might have to modify the rear spacing of your frame to fit the wider axle spacing of wheels having space for freewheels or cassettes with the number of cogs you want. What you need to do is to measure the spacing between your rear dropouts, For 7 speeds you need at least 126mm spacing. For 8 or more speeds you need 130mm
