Is degreasing the chain a matter of just spraying it down and letting the cleaner do it's job, or do I need to get in and scrub the chain with a rag or something? Such a newb question. LOL.

Was out on my ride on Saturday. Had a guy pass me up who appeared to be working no harder, or even less than I was. I don't believe he was on a TT bike, but a road bike. But he did have way nicer wheels than I did. Got to find out the secret to that. I was doing around 18mph at the time and he probably passed me up doing 20mph or so and it looked effortless.
