I ride hilly and mountainous terrain in northern Colorado. I get relatively good agreement when I ride the same routes with 2-5000 feet of climbing. A peak elevation may vary by plus or minus feet 100 feet and total by a bit more. After riding each one dozens of times, I know what I'm in for. The worst gradient is what concerns me now. I'm carrying extra low gears since I'll soon be 71. I still weigh 135. My lowest two gear ratios are 30/38 and 30/44, compared to last year's 30/36. I probably won't use the lowest, but the 30/38 will certainly get used on the steepest sections. I keep the percent grade, gear combo and speed on display at all times.
