I should clarify that most of the hills I climb are short and steep with 15 to 20percent grades. I, for one, cannot spin at my usual 92 rpm on these hills. I don't have enough gears, even with a triple and even if I did, I would blow up before reaching the top. I'm sure there are people out there who can do it; just not me.

While on my bike tour in Tennessee, I did some longer, "mountain" climbs that had more gentle grades. I generally picked a gear that allowed me to spin at or near my usual cadence. Those climbs are a different kettle of fish from my usual fare.

For rollers, I either power over them or drop down only a gear or two. Unless I'm tired and then all bets are off!
