While the snapjack says it isn't for the front tire, folks still use it for that - you just put it up under the front of the frame. Not sure about the low clearance of our bikes, though, so that may not work. Theoretically, if all one wanted to do was achieve the tripod effect for the front or the back, then one of those small hydraulic bottle jacks would work, depending on your luggage setup. Heavy, but small enough to fit in a saddlebag.You would have to figure out how to make sure it didn't slip as the bike came up, but it is an option.
Gray is faster. Itís science.
