Whoa, that weighs more than when I had my alloy gravel frameset!
I think it's a bit more of balancing act trying to weight weenie a gravel bike since durability and ride conditions are important factors to keep in mind. I might even consider getting an older Crux frameset at this point if I want to drop more weight.
It's not super light by any means but most stock name brand gravel bikes are over this. What alloy bike did you have that was lighter ? I had a Trek Checkpoint that was 21 lbs. I think without any of the junk (bags, tools, spare tube, food, bottles, f & r lights, garmin, gopro etc) on there it's 18 lbs. I have a Colnago Master that is 18 lbs LOL
You mention the Crux but where I live that bike is $10k - $15k. I have about $3500 into this with the SRAM wireless. I doubt the Crux would give me 4x as much fun.
