I suspect the hubs were just shot, since I had never re-greased them and they were 10 years old (<5k miles though).

In any case, on both my new and testing co-workers bikes my speed improved by about 3 mph. When they rode my bike, they lost about 3 mph. Both other testers agreed the bike was "slow".
