Long story short, son moved out and the place where he is renting has storage in the garage but will not allow him to make holes in the wall for such as a bike hanger. His bike is ~2012 Specialized A1 with the Sora group. Traditionally, I would not put a kick stand on a road bike of that nature but would be better than having it tenuously leaned against a wall falling over and most importantly into the VERY nice car that homeowner has parked in close proximity.

So, the jungle site has quite a few options in the roughly $10 range:
There is the "square block and bolt" type that mount right behind the bottom bracket. I don't think this one will fit on his bike due to how narrow the tubes are there as well as the routing of the cables.
There is one that is semi oval and uses a clamp with 4 screws which mounts to the chain stay. This one seems like it would work well but am concerned about the shape of it in relation to the tubes on this bike. I have never personally used this type.
There is the one that mounts at the rear axle. My own experience with this type is that the bike is unstable and falls over anyway.

For those of you using the one that mounts to the chain stay, how do you select, or does it even matter in relation to the shape of the stay? Do those type come with a variety of spacers/rubber/etc. to allow for a variety of applications?
