I had one day where I had 5 "flats" and it was a relative breeze because I had a Road Morph. There are other similar pumps. It is basically a very small pump that one can use like a floor pump, so one can pump with twice the force as both hands on are on the plunger and the backforce is coming from the earth. Mine has a built in gage that seems accurate enough. Road morph; properly matched rims and tires; quick stick, and self adhesive patches, pretty much make repairing flat a pleasure.
