I have an older voodoo CX bike I turned into my gravel bike.
It started at 21.75lbs including pedals. I broke my light (cheap) seatpost, got a bottle holder, decided I wanted an arch for my rear brake, and added a chain guide for the 1X. It put the bike at approximately 22.5 depending on how much sealant I am using. I kept the 900+ gm steel fork the frame came with.
So it's not particularly light but with the light wheels and 40x42 low gear, it rides light and quick. I wouldn't want it any heavier but I don't notice the weight.
I typically take it on washboards, long climbs, and the local (shale covered) mountain bike trails. I don't race.
