I'm 55 yo and I just started biking last year with the goal of completing a 3-day century charity event which I did with no problems. Not knowing much about road bikes, I did my research and trying different bikes and ended up buying a Giant Defy 2 from one of our LBS for this event. I'm now hooked on biking as a form of exercise and recreation and even dropped ~15lbs in the process. I have plans for both a century and metric century later this summer. My 26 yo son has now moved back home and wants to join me on my morning training and weekend long rides. Of course he has no bike which is my good fortune as I would give him my Giant since we are both about the same size.
Given my good fortune and my wife's OK to get a better bike, I've been trying various carbon frame bikes with better components. So far I've demoed the following bikes:
Diamondback Podium 6
Giant Composite 1
Trek Domane 5.2
Trek Domane 4.3
Specialized Roubaix SL4 Comp
After riding and testing these bikes, I'm sold on the Trek Domane. The rode was so much smoother, the Isospeed really works and the bike fit and felt great. Now my dilemma is which Trek model as I am trying to choose between the 4.3, 4.7 and 5.2.
I'm looking for feedback about these Trek Domane models. The specs highlights the differences between each of the models but I'm not sure if I could really feel or tell a performance difference between them. Further, the cost of the Domane 5.2 would really stretch the budget compared to the other models but I'm in it for the long term. Looking forward to learning from everybody's experience about these models as I make my decision.
