Shaped tubing

i remember reading Litespeed catalogs as they described why their various shaped tubing produced a superior racing frame. Several models only offered for 1 or 2 years. They experimented a lot in the 90’s.

Didn’t Armstrong ride a rebadged Litespeed time trial bike. The aero shaped downtube was massive, not unlike some CF designs later.

The reborn company did the same with some models.
