Help understanding effect of Crankarm length on gear ratios Trying to learn more about bike fit and gearing, and having trouble understanding the effect of crankarm length on gearing. In an article on bicycling.com it states

"The relative jumps between gears stay the same, but the overall range will feel slightly easier to pedal, or smaller, with shorter cranks and harder with longer ones."

It makes sense to me that crankarm length would have an effect on how hard it feels to spin a certain ratio, but instinctively I would assume the opposite effect described here -- that a longer arm would give more leverage and make the overall range feel lower.

I think the article you reference is in error. Obviously a longer crank arm gives more leverage, requiring less pedaling force to move the bike but requiring a faster pedaling cadence the pedal to moved faster around a larger circle (same angle/unit time, more distance/unit time). The rider's leg must therefore extend further and more quickly.
