I stumbled across a kickstand jack a wile back that looked great. Went to buy it and they were not making it due to manufacturing problems. Now I can't find it anyware. So I made my own, and it worked great. I have heard horror stories of trying to change tubes and tires, or laying the bike on its side to work on it. I have been debating on making some for sell. Because it has saved me on a trip, in 30min or under me and my father pulled the tire off, swaped out the tube, pumped up by hand, put it back together and back on the road. My only interest in selling them is to play for parts and my time.
