I have good quality Parts on my gravel bike. That being said it's not built for a weight weenie. The frame and fork alone of my Soma Wolverine is over 5 pounds I think. The wheels are Shimano XT hubs so they're a little heavier than the Hope hubs that are on my mountain bike. I'm guessing my Gravel bike probably weighs about 25 to 30 pounds. I'm running 42 tires and they're not tubeless so I have inner tubes in there as well. And this thing rides like a dream. I don't think I would want a sub 20 pound bike to be riding on the gravel roads that we have here in Iowa. That is just my opinion.
