Ha! I've always thought it was just the opposite. The sprinters are the ones with explosive power = mashers, while the distance folks are more about economy = spinners.

Maybe there are no predictable rules about who turns out to be mashers vs. spinners.

For the OP, 90 is just thought of as an 'ideal' cadence with the best balance between energy expenditure vs. speed/power. Your ideal cadence may turn out to be a bit higher or a bit lower. Nevertheless, I do think it would be worth your while to invest in a cyclocomputer with cadence and try to spin at 90 for starters and then refine your ideal cadence from there.
