I hate paying for "chrome" valve caps - I just want nice, simple caps that keep my expensive bikes looking good. Black plastic hubcaps seem cheap to me on expensive cars. Of course, who even notices? Regardless, at around $0.22 per cap for a $50 purchase, these caps are cheaper than some typical metal 4-piece cap sets. More importantly, if they get lost at the tire shop or replaced with cheap plastic caps, or if they're ever stolen, it's as easy as applying without wasting a second! Heck I gotta start selling them at Car's & Coffee for $1 each I bet they're selling like hotcakes! Simple, beautiful replacement with rubber seal. I saw a comment about valve stem welding and can't see why this is a special case - it's regular plain clean German caps!
