Ah, yes. the time and effort saved by not using caps. The wattage savings and efficiency are mind boggling.
I, instead am an avid presta cap fiend. In fact, I hover popular biking routes and when I see parked bikes with no caps , I sneak over and screw caps on every naked valve. Then I distance myself and watch the show begin as riders scratch their heads in amazement on how caps spontaneously appeared.
