Y'all seem to know a lot about bikes. Here's the context. I currently ride an unmodified giant roam 1 from 2016 https://99spokes.com/bikes/giant/2016/roam-1. Mostly road, some mild gravel.
I'm looking to increase my biking overall, definitely add more dirt and light gravel, so I'm curious about bike upgrades.
In the same overloaded "do it all space" what does a significant upgrade look like, and what would the real gain be of an upgrade? Is it even worth it, or would I be better off doing something like changing parts on my current bike.
Related question, looking at a bike like mine, what's the performance "bottleneck" (other than of course, me)? Weight? The gearing etc? Frame shape? Wheels?
I'm definitely bike and gear curious, but looking to be an informed shopper.
