I see where you're coming from, and carbon fiber and titanium do have their advantages in terms of performance and durability. But let's not forget that cycling is not just about racing down a mountain trail or tearing through city streets. For many of us, it's about enjoying the ride, feeling the wind in our faces, and taking in the scenery. And in those situations, a frame's weight and stiffness might not be the most critical factors.
I'm curious, have you ever tried riding a steel or aluminum bike for a long, leisurely ride? The smoothness of the ride and the classic feel of these materials can be quite appealing. And while they may not be as lightweight as carbon fiber or titanium, the difference might not be as significant as some people think.
Of course, if you're a competitive cyclist or someone who puts their bike through a lot of wear and tear, then carbon fiber or titanium might be the way to go. But for the rest of us, I think there's a lot to be said for the simplicity, durability, and classic feel of steel and aluminum frames. What do you think?
