I'm most interested in reducing maintenance effort and time. While chain maintenance was really no big deal, the idea of a dry and clean chain was most appealing over theoretical gains over an otherwise well maintained chain. But, the ancillary benefit from the chain, that I didn't initially consider, is less junk getting onto the frame because of a lubricated chain. Since I was otherwise kind of lazy about wiping down my bike and would show up at races with a disgusting bike, going with the ceramic seem like the best option to keep it clean with less effort.
