60 is probably too low... unless you're on a single-speed - but even then! There is actually an optimal spin rate for a cyclist, at which point there are no more gains in "horse power." I could find it if anybody cared about the exact number(higher than 100rpm)

Don't forget how to work out of the saddle either, too many roadies get fixated on "sit and spin." That is my opinion anyways, I always hear sit and spin as panacea for increased performance.
