I was riding on the Dismal Swamp Canal Trail a few days ago and came across a cyclist walking his MTB. He flatted and didn't have anything for repairs. I always carry a patch kit, tube, Frame Pump & CO2.
Long story short--- we patched the tube but I had to use one of my CO2 cartidges to inflate his tire. I couldn't figure out how to use my Topeak Road Morph pump on a Schrader valve.
How do I convert between Presta and Schrader valves??
Thanks in advance.
