# revs per mile

I’ve been following the revs per minute thread, however, this got me to thinking in revs per mile, and when I was perusing the Unicycle across Minnesota website, I did a little math.

The distance travelled by the participants was 479 miles. A Coker with nominal tire diameter of 36 inches @ 80 rpm would take 55.91 hours of riding time, and 268,348 crank revolutions, to go the distance.

A “road” uni with nominal tire diameter of 28 inches would have to spin 100 rpm to complete the trip in about the same time, 55.52 hours. The shocker was it would require 345,019 crank revs, 76,671 more than the Coker.

It makes me tired just to think about it.

My legs start aching again. I was one of the 28" riders.

With my geared up 26" i would need 234618 crank revolutions.

33730 less than a coker.

So, Frank, how is YOUR geared uni doing? Have you been riding it? Any noticeable increase in backlash? Have you swapped it into a 700c rim yet?
