It never occurred to me to reset the odo. After all, the bike and I have gone all those miles. If I delete the numbers, I've deleted the effort. Nope, nope, nope, I ain't gonna do that! And besides, I want to be out on a ride someday with a camera and capture the roll-over to 0.00 again. {sigh} Bliss.
That being said, it's your bike, your computer, your psyche. I really don't think there are any bike computer police around to enforce any rules, one way or another. Do what feels like the right thing to you.
Give big space to the festive dog that make sport in the roadway. Avoid entanglement with your wheel spoke.
