The "What is the truth behind bike weight..." thread makes me want to raise this issue.
I have two sets of 27" wheels, one very old and one fairly new. If I spin their rear wheels by hand, both will spin for approximately a minute. I also have two sets of 700cc wheels, one old and one almost new. If I spin their rear wheels, both will stop at approximately 35 seconds.
So, how - if at all - does the difference in unloaded spinning duration translate into on-road performance?
