Gearing is all new to me, so I have a lot to learn.

Our terrain is generally what I'd consider "flat prairie," since Dallas was built on prairie farmland. But there are creeks and streams in our neighborhood, and that means a lot of streets with relatively steep hills where they drop down to the water. So I can devise routes that are very hilly or flat.

When I start riding longer distances and have to get out on the highways ... Hmm, I think it's pretty flat around here, but I also intend to drive to East Texas to do some riding where it's pretty hilly in some areas.

So how do I know what kind of gearing to get? (Oh wait, ask at the LBS?)
