One reason the folding kick-stand interested me is because I've been using a car jack to lift up my back wheel to grease/clean the chain. The car jack works ok but puts a little more weight on the kick stand than normal (because it raises the rear end at an angle while the bike is on its stand). I didn't think this was an issue, but could this possibly cause damage to the kickstand, maybe even causing it to "fold"??
I dont' think the car jack distributes all that much weight to the kick stand, but it is lifting at an angle, which must be putting a little extra weight on it, I would think.
