So it only matters on basically every classic non time trial race?

Did you ignore the part where GP was talking about the tradeoffs made, and how aero improvements are almost always worth the extra weight?

It's about optimizing the whole system, not just one part of it.

With the speeds the pro's climb these mountains, aero is still a big deal. For you and me slogging along it's almost all weight that matters. But not for the pros.

Keep in mind that arodynamic drag is not a function of ground speed, but airspeed. If you ride slowly in a relatively windy place, your airspeed can easily be twice of your ground speed.

That said, given how many of us are overweight, worrying about a couple of kilos on the bike is funny talk anyway.
