26" rear wheel for 700c road bike on a trainer?

Any reason not to use a smaller diameter wheel on a trainer? I've got an aluminum Trek 1200 with out a rear wheel, but have a bunch of 26" wheels. I was going to mount a dumb trainer on a homemade rocker board so the bike will be pretty high up. I'm pretty sure "pedal strike" will be a non issue.

If the gearing works, give it a shot. Why not?

Zwift doesn't really care what kind of bike you ride as it calculates your power based on how fast your pedaling but this probably would vary based on whether you are using a smart wheel on/wheel off trainer or a dumb trainer. If you are using a wheel on trainer the tire you use might also have an impact on the numbers you produce on Zwift.

I'm sure there's a more detailed analysis out there somewhere if you were more interested.

OP is talking about a dumb trainer. Only thing affected by wheel size here is the overall gearing. So the smaller rear wheel will just make the dumb trainer a littler easier to pedal in any specific gear.

Find a narrow tire so it fits between the stays.

I see no issues with your plan as long as you have clearance.

If you're using a dumb drainer without a power meter, be sure to get the wheel diameter put in their correctly as the power estimation calculations will be based on speed of wheel rotations, and that'll be different for differently sized wheels.
