I've been complaining about the gearing on my bike a lot lately, but during today's ride I noticed something odd: Gerrit and I, who both have a low gear of "39-25", were not pedalling at the same rate even when in our lowest gears. This struck me as 100% impossible. Tire widths might make a slight difference, but not nearly enough to account for what I was seeing when I simply compared his pedal RPMs to my own as we were climbing a steep hill.

So, just now, I did something silly: I actually looked at my gears. Turns out my rear cassette is a 12-23, not a 12-25. This works out well for me, because I can buy a 12-27 cassette for way less than the cost of a compact crankset.
