I have been looking at both and have ridden both. Exactly same components. Carbon vs. aluminum. This is my first real road bike and I need guidance. I like both and cant really tell that much difference. Only about $400 difference. Any help would be appreciated.
You must be getting the 2.3 for a good price, if there is $400 between them. You really cannot go wrong with either.
But, the 4.5 sure is sexy, isn't it? Plus the fork on the 4.5 is much better than the 2.3.
TREK's TCT carbon continuously gets snubbed because it isn't "OCLV" BUT it is still probably better than many other offerings.
Plus, despite the new tech on the 5.x and 6.x Madones, I really like the fact that the 4.x Madones keep the traditional fittings. I wouldn't hesitate to race either bike. It really comes down to what do you want: all carbon or an Aluminum/Carbon mix? Hell it may even come down to color choice!
Good luck, you can't go wrong with either
