Lezyne Pump - Large
If you use bigger saddlebags, this is the "mini" pump to get. It's got a fat barrel for bigger tires, a nice handle that fits well in your palm and a fold out foot pad so you can keep it steady. The hose is double sided - one for presta and one for shrader - and prevents damaging the valve core while pumping.
Lezyne calls this the Micro Floor Drive HV
