While I agree that personal preferences and riding styles significantly impact the choice between durability and lightness, I'd like to point out that the perception of a "lighter" bike may not always translate to better performance. A skilled cyclist might maneuver a lighter bike with ease, but that same bike might become a handful on technical terrains or in adverse weather conditions.
Moreover, the notion that carbon frames are inherently lighter than aluminum frames is not always accurate. As you mentioned, optimized aluminum tubing can provide a competitive advantage in weight reduction. Manufacturers can manipulate the design and construction of both materials to achieve different goals, prioritizing factors such as stiffness, durability, or weight.
When it comes to touring cyclists, the added weight of accessories like fenders or racks might make a sturdier bike, like the Salsa Warbird Carbon, more appealing. However, it's essential to recognize that these accessories can also be added to lighter bikes, like the Canyon Grail AL 6.0, to accommodate the needs of various cyclists.
Ultimately, being well-informed about the implications of bike weight, durability, and design choices is crucial. But, so is understanding how these factors interact with personal preferences and riding styles. How do you balance these considerations when selecting a bike for mixed-surface riding?
