I could, but then I'd have to take the silly useless cap off, and put it back on every time I want to bring my tires back up to the proper pressure, and if I get a flat out on the road I have TWO silly useless caps and TWO silly useless lockrings to deal with, generally while working in the cold and wet (because flats happen more often then) with cold-numbed, clumsy fingers.
