Personalized tubulars? Everyone had them in the 70s. And we didn’t need a Sharpie.After the tire was mounted, you’d get out the Bic ballpoint and write your name on the sidewall near the valve. Kept them from getting mixed up with team mate’s wheels when traveling to races and gave you a better chance of getting your wheels back if you were lucky enough to go to a race that had a wheel van. And in the US anybody who was selected to go to an international event always wrote USA after their name. Even after the event, those letters were a long lasting bit of subtle intimidation on the starting line.
