7 to 8 speed freewheel cassette change

Hi,

I am currently building up a bike. The rear wheel that I have has a 7 speed freewheel cassette on it, but my shifters are 8 speed. If I buy an 8 speed freewheel cassette, like the one below, will it fit and work ok? I'm hoping to avoid buying a new rear hub and having to re build the whole wheel.

It depends on you wheels and frame. The 8 speed is wider, so may not fit. Though you may be able to respace the axle and redish the wheel.
