Near Columbus Circle I spotted a bike with corks as bar end plugs . . .
. . . as well as a seat tube plug. I am inclined to think this is an anti-theft/weather hack. My assumption is the owner takes the seat when parking and plugs the bar end so water does not enter the frame when it rains.
Not sure of the vintage of the liquids digested to complete this hack, but I will just call it a vintage wine hack. The seat tube plug does appear to be of the bubbly variety. If you have found a creative use for cork feel free to contact us.
My customary beverage of choice is beer and thus I am interested to know if anyone has found a bike related use for bottle caps. We have seen beer cans used as fenders and mud flaps, but I do not think I have seen a beer cap hack of any kind. If you have found a use or have witnessed something, give us a shout out.
