There is. There isn't much but it is there. Think of rocking on rocking chairs with various radius rockers.
Dr. Lucien Sanchez:
The 'wheel effect' matters for the side to side balance point in manuals and going round corners and stuff - the pivot point for side to side is where the wheel meets the ground
With the up and down motion you and the bike revolve around the axle NOT where the wheel makes contact with the ground
However it's pretty much impossible to manual properly without adjusting weight in all directions (same as riding along in a straight line isn't actually straight) so there is a difference in wheel size with same length chainstays

IF you had a perfectly smooth rolling hub, then the bike would only really pivot around the hub axle as long as you stay off the brake, but as soon as you start touching the brake it will start to roll around the tyre as well. So any friction in the hub (hubs are very smooth but not perfect, and when you are balancing you may notice this, especially if there is significant drag in your driver say if it is a bushing one rather than one with proper rolling element bearings and you run a tight chain) will be a similar effect.

That sounds true . . . but I would add any time you are off the balance point, that will happen. Rather than talk about manuals, let's look at peg wheelies and hang 5's (or any other flatland peg trick). You are standing on the axle. I have ridden flatland on 24"s. www.youtube.com/watch?v=CQA2E71iWUE It's harder to get up into the hang 5; once you're fully locked in it's not any different, but any time you make an adjustment, it's slower.
And . . . to get this thread back to 22"s, here's my buddy Vernon on his InDust 2Ton 22". He's getting a short run of 4 more frames made right now; they're almost done. Can't wait to ride one.
Dr. Lucien Sanchez:
But even using the brake your pivot point is still around the axle?
The bushing in a driver shouldn't have an effect whilst manualling, only the spring/pawl set up?
Tha hang 5 thing, maybe cause there is marginally more weight further away from the rider than a smaller wheel?
Actually thinking about it maybe a bigger size wheel of similar weight has more angular momentum (gyroscope)?
I kinda like the look of 22" bikes
