Road Morph in any of it's forms- is one of the best around. Just don't go for the Mini Morph unless you are stuck for space. It still works but with only half the volume of the Road morph- it takes twice as long to pump a tyre up.

On top of that get a wedge. Small bag to fit under the saddle. In it I carry one spare tube- 2x Tyre levers- repair kit and a multitool. No need to carry much as you won't need it with your luck.
