I smirk when I see the Trek ad for the emonda. They sell it as a climbing machine. My Rival version is 19 pounds. Although it is a little portly, I still enjoy riding it. On the cooler days, the shifters are supreme when wearing gloves. It is a nice machine for longer rides. The older madones with rim brakes would be better if seconds mattered.
My madone is 17 pounds. Di2 is nice; I set mine up so you really only need to use the right shifter. It changes the front ring as needed. I guarantee the frame is as rough as my aluminum cannondale.
Marketing, marketing marketing. How else can they sell new bikes. We might as well face one thing; might as well have a durable good in the garage since the value of our money is evaporating on a daily basis.
Sorry I'm partial to Trek. My local dealer is about as trustworthy as you will find.
