Spare rear wheel

[2wd]

I just bought a Tacx Turbo Trainer and was wondering rather than change the tyre each time for a trainer tyre, either buying a fully built spare wheel or building one

Never built one before so sorry if it's a numpty question, but what bits do I need

I'm assuming

wheel
9 speed cassette

Anything else required?

NB its for a 27 speed Allez Sport

Thanks

I was thinking of doing the same but the only problem is that you'll need to re-tune index the gears everytime you change the wheel. You could buy exactly the same wheel and components as your current wheel and it'll still differ, maybe only by mm but those mm will make a difference.
