Yup, second stem. KC8QVO described it pretty well.
I am assuming you would use a stem sized for 26mm handlebars, not 31.8mm. If you go to a hardware store and ask for a short piece of PVC pipe, it is not 1 inch. Nominal 3/4 inch pipe size is 1.050 inches outside diameter (or 26.67mm), so you would be buying 3/4 inch pipe. I used PVC pipe on one bike, cut down some handlebars that I was not using on a couple other bikes.
If in doubt bring the stem to the store with you to check sizing.
I like the second stem as it lowers the bar bag. More photos of my bikes and second stem setups at this post
