>>1480598my old blue frame with bullhorns (currently not rideable) is Blue Bull.
back in the 90s when I drank malt liquor, and before Red Bull energy drink was sold in the west, there was a malt liquor called Red Bull. the better-known and older Schlitz Malt Liquor's mascot was a bull, the tv ads used to have live bulls bursting out of store's beer coolers, but the bull logo on the label was blue. so we used to differentiate by saying either Red Bull or Blue Bull.
so, I removed the Trek head badge (just stuck on with double-sided foam tape, pretty low class) and epoxied a bottlecap on there.
