I was feeling ambitious today and started wrenching on the gf's mini.

I put a Maxxis tire on the 10" front rim I got for it, and that went pretty well without incident.

I had to use a punch to drive the rear axle out, seems that the previous owner never greased the axle. No big deal, I got it out and gave it a good cleaning with a scotch brite pad.

When I went to pull the stock knobby off, the tube just kept coming out. I could hardly believe it. Some cannibal used a 20" bicycle tube
