Basil, like all Bromptons, came with nifty metal tire valves and these thrilling clear stem caps:
Alas, when Basil’s rear tire and tube were replaced, the more pedestrian valve was installed.
Well, maybe “pedestrian” isn’t exactly the right word, under the circumstances.
I had anticipated the potential loss of the lovely transparent cap, so I saved it, removing it before Basil went into the shop. However, it snapped in two a few days later as I was removing it preparatory to checking the air pressure. I was shocked when I realized how brittle the plastic is.
I stole the black cap from Mr. Diarist’s mountain bike. Don’t tell anyone.
