I rode a monocog flight the other day, and had to have one.. Well money is tight, and 100$ is cheaper than 800$ so I converted the stumpy.

Surly spacer kit, rear cog, and chainring. I have a 20 rear and 32 front till I get used to it more, and will work my way to a 16t. I love that surly stuff, I managed to get the chainline perfect?

Had the flats on to ride around tonight after I put it together.

Rides great, need to put more air in the tires, and the fork, but overall very good.
