Hi everyone,  I am a newbie in that very huge world of components from China. I didn't build my gravel bike, but little by little, I want to make some upgrades. I love my bike,  very comfortable and I have ridden all over the world with it. The upgrade I am looking into now are carbon wheels, 40 pr 50 section. I have a Tiagra 10 speed groupset which have served me well for the past 2 years. I appreciate your suggestions.
