wondered what the cork dangling from the seat was for...
timers used wine corks to hold the ends of their bar tape in place.
in racing if you start to crack, it could be said that you were beginning
to unravel... therefore, it became a tradition to carry an extra cork
as shown on this bike, so metaphorically, you always had 'something
extra' to keep yourself from unravelling on a ride.
think this was started by ted ernst of the southbay wheelmen, but i
could be wrong.
