I'm writing a book.
It's called Gearing For Dummies.

It goes like this.

Front: Big, Medium, Little. (Those are on my left stem, uppest being Big.)

Back: Slow, Less Slow, Fairly easy, easier, much easier, easiest. (These are on my right stem, downest being Slowest.)

When I'm going up hill, I change into Medium and feel around the easy gears.

When I'm goin' down a hill, I change into Big and Slow.

My DH gave me a hint the other day, on some rollers.
He said, try just shifting only the left for awhile, between Big and Medium.
You mean, only shift between two gears?
Yep.
It was refreshing.
