Alte Zipp-tubular werden natürlich schlechter sein als neue Zipp-clincher. Hat aber nix mit den Reifen zu tun sondern mit alt vs. neu.

Nein.

Zipp compared clincher and tubular versions of the same tires on identically shaped clincher and tubular wheels and found the clinchers to be more aerodynamic. Tubular casings are round when inflated (although tread isn’t always), but clincher tires pinch inward at the bead, creating a tire that is taller than wide. This shape influences wind drag, and makes the Super-9 Carbon Clincher even more aerodynamic than the tubular alternative.
