I saw something the other day that made my mind go WTF.
I stopped at the grocery store, I noticed this bike locked to the bike rack. I was admiring it and then I noticed that the front tire had a Presta valve, and that the rear tire had a Schrader valve.
I have never seen that before, I can't fathom why anyone would do that. As an aside there wasn't an airpump on the bike either.
Any thoughts?
