I know this will not be a popular choice here but I prefer to buy American when ever I can and don't mind paying the extra $$ to do so. So I went with the Cyclepump from Best Rest Products.

A few years ago I bought one of those cheap cigarette lighter tire pumps at Harbor Freight for less than 10 bucks. I kept it in the back of my Durango for that just in case moment. I am going to Sturgis in a week so it is now in my saddlebag next to a small cheap plastic tool box stuffed with emergency tools and a tire plugging kit. Hopefully I won't need any of it. But it sure is nice to have.

I also have my bottle of Lemon Pledge and microfiber towels in there also.
