Excerpt:
"Joe Myers rides a unicycle with a 36” wheel, which used to be the gold standard for long-distance riding. However in recent years it has become possible to buy geared unicycles. Building gears for a unicycle is tricky because you need to be able to pedal forwards and backwards, and there can be very little looseness in the drive-train when you switch from forwards to backwards. However these challenges have been overcome and it is possible to buy a hub with internal gearing that can switch from 1:1 to 1.5:1 mode with a click of the rider’s heel. This means that long-distance riders can choose between a 36” wheel with no gearing, a 29” wheel with a geared hub (in high gear this is equivalent to a 43.5” wheel), or a 36” wheel with a geared hub (in high gear this is equivalent to a 54” wheel). Some riders use ungeared 29” wheels, but it is very difficult to maintain a competitive speed because even a cadence (pedal revolutions per minute) of over 100 will only propel you at 14 km/h."

The chick with the green boa is a man, man.

There's a dude in a blue prom gown and neon green beehive riding a unicycle with a 36" wheel and you spot the dude with the boa?

It was a drag race. I'm the one with the flag pole and pigtails.

As for geared unicycles: a few years ago Schlumpf adapted their two speed internally geared bottom bracket into a unicycle hub. It sells for around $900.

Shaves legs == FG cyclist? (see: "The hardest part of riding FG" - thread)

Well yea, I was thinking; "Jesus that chick has a head the size of a truck".
And then I figured it out.
