Necro-posting... that's funny... and true! I was searching for exactly what this topic offered, so rather than start a new one, I raised this one from the dead.

Highest gear - got it. I always thought of highest gear like a motorcycle - the one you switch to to go the fastest... which makes sense now .

I've got a Schwinn something-or-another 21-speed mountain bike with big knobby tires, though I am strictly a road rider.

Thanks for your reply.
