Since I bought a 2021 Domane AL 5 disc this past summer I can only speak to that. I just turned 70 and ride 2-3 times a week usually for 2+ hours or so. Never been uncomfortable on this bike. My LBS did a great job fitting me for the bike, close to an hour of adjusting the bike for my size and posture. Many hear have extolled the virtues of the importance of a proper fitting bike and I would agree 100%. Whatever you chose, where you buy maybe just as important as what you buy, especially if they can understand your goals and what you expect out of the bike. I love my Trek, it’s probably more bike than I need but it’s certainly keeping me motivated to keep riding. Good luck and let us know how it ends up.
