Trainer wheel & tire & cassette
Okay I am looking to use a dedicated tire/wheel combo with a new cassette with different ratio for my trainer setup. The cassette is a 11-28 and my current is a 11-32 I ride on the road with.
To setup the dedicated trainer combo should I use the equation for determining chain length which is:
L=Chain length
C= Chain stay length
F= Front largest chain ring count
R= Cassette largest tooth count
L = 2 (C) + (F/4 + R/4 + 1)
Or just use the current chain which would suffice for trainer days????
My current setup with this equation should be a 54" chain and the new setup be a 53" chain length.

Jesus.
I hate trainer rides enough already, if I had to change chains every time I don't think I'd ever ride.
Just stick it in and go.

With the lack of changing terrain, I found I rarely change gears while on the trainer. I might as well have been riding my fixed gear.

As long as your cassette doesn't have a bigger big cog you'll be fine using the current chain. The big-big (ring/cog) combo determines the chain length's limit. If the chain is too short something bad will happen - rear wheel pops out, derailleur/chain jams, etc.
If you had, say, a 12-25 on your "outside" wheel and a 12-32 on your "inside" wheel then you'd need to have a chain long enough for your inside wheel.
A good number of riders switch between different ratio cassettes without changing the chain - all they need to do is make sure the chain can handle the biggest big-big combo.

I have enough wheels that I dedicated an old one to trainer use, with trainer tire and it's own cassette. I do use the same chain though

Gearing for a trainer is controlled by the resistance curve of the trainer. Outdoors it's controlled by weight and terrain. I find I want a narrower cassette for the trainer, personally.

you may find the trainer will destroy a normal tire pretty quickly due to heat build up, If your not already considering it get a the tire specially made for trainers like the Tacx trainier tire, https://www.wiggle.co.uk/tacx-trainer...or-road-bikes/
If your planning to ride rollers this is less of an issue and you can use your normal wheels.
