The Airborne looks like it will be about a half lb less weight than the Trek Emonda in the same size. One might suppose that the Trek might be more Aero but like the Airborne, it has large diameter tubes that had no attempt at being aero in design. Also one would have to question whether small diameter round steel tubes are less aero than the much larger diameter of, say, the Pinarello frameset. I can't say that I ever noticed any difference between the late Basso Loto I had and the Trek Madone which was supposedly quite aero.

Of course I'm not a pro rider and I very seldom even approach the speeds that the pros commonly get in the peloton.

But isn't that the entire point of Aero? To give you that very small gain when you ride at those sorts of speeds all day long? You sure as hell aren't going to put out these sorts of power and my entire reason for posting this is to tell you that you sure as hell aren't going to gain enough to even consider spending large amounts of money on a fantasy bike to make it worth your while.

Another point - Components are now more expensive than good frames. But China is invading that space as well. You can get a Sensah 11 speed group complete for $200. They have been working their way up from not very reliable and seem to have now hit a high enough reliability standard that I will give them a test. The failure points seem to be the levers on the previous versions but that supposedly has been reengineered to be reliable. And if it weren't so you could always buy SRAM levers which have the same pull ratio and we know that those levers are reliable. And you would still save a pile of money. I'll see after I get rid of all of my extraneous bikes.
