My Schlumpf Has Arrived!

Today my Schlumpf KH hub was delivered!
Once I build it into a wheel, it will allow me to have a geared uni (aka guni).
There's a shaft that runs through it. Push it in on one side and it's the usual 1:1 drive like a normal unicycle. Push it in the other side and it's a 1:1.5 ratio.
So for every one rotation of my cranks, the wheel will actually go around 1.5 times.
It should be fun, but it will take some time to build it into a wheel. I still have to buy spokes, and then have a bike shop put it together.
