I've a mid 70's Zeus bike here and it has a tubing decal on the downtube that reads:
'A' QUALITY -BUTTED-
REYNOLDS (on a diagonal from bottom left up to top right)
FRAME TUBES FORKS AND STAYS.
All of the text is a bright yellow on a black field with a yellow border.
Anyone know what this tubing is (besides steel!)? Any info out there about this stuff?
Thanks
