A fabulous listen & one that I personally can relate to. I am 163 cm tall with long legs (let's just say that most MTB cycling pants feel more like knickers on me). I have always wanted more room in the front of any bike so the long front centre suites me.
Related to the issue of road cycles and their geometry. I remember reading an article after the first season of the 7-Eleven team competing in the Tour de France. When Ben Serotta was building their frames for the excursion he recommended more relaxed angles for their bikes. Most of the riders went with the suggestions. A major hold-out was Davis Phinney. As a team leader & one of the major talents he wanted to stay with what he knew. So his frames remained tight & (relatively) steep.
By the end of the Tour, Phinney had the mechanics filing down his seat-post clamps so that he could move his seat further back for a slacker STA. I think that when we talk about the professional peloton riding the grand tours that the bikes need to be comfortable as well as efficient. Six to eight hours at an average speed of 40kmh for one month require a different steed than one built for two or three hours per day.
Horses for courses.
