I currently own a Giant OCR-2 road bike that I purchased new (4) years ago. I am now at the point where I am considering the purchase of another bike. This time, I am in the market for a “Duel Sport” type of a bike. This way, I’ll be able to ride on both the paved roads and some unpaved (single or two track) surfaces. I have pretty much narrowed it down to either the Trek DS 8.3 or the Giant Roam 1 (both have mechanical disc brakes). My real question is: which of these (2) bikes have the better (more reliable) components (derailleurs, crank, cassette, brakes, wheels…….)? I do realize that I will be test riding these (2) bikes, but with all things being equal, if it comes down to components, I would like to purchase the bike with the "better" components.
