This. When I used to ride (80s and 90s), a lot of people would try to shave weight and you saw some crazy stuff to get the bike down to 13-15 pounds. Bikes would be dangerously fragile because people would drill stuff and make wheels with fewer and fewer spokes. 17-19 lbs was really where the balance was between safe and light... and having equipment fail cost you a race really sucked... and people were getting hurt.
