I'd suggest getting a second rear wheel built with the same rim and hub and cassette. Just swapping the wheel is much less trouble than changing the tire, and one wheel and a cassette is much less expensive and takes up a lot less room than another bike. Alternatively, there are fancy trainers that replace the rear wheel (e.g. Wahoo Kicker). Though they are expensive as trainers go, I think they're cheaper than a new Rivendell, and might make your trainer time more enjoyable too.
If you do go the second bike route, I think it's the new one that ends up on the trainer. What with shorter daylight, puddles and whatnot, your Homer is going to be what you want on the road in your use case. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
