A large Nimble 9 frame for the 2020 model is 5.8lbs naked and 6,27lbs with axle, dropout and hardware. I will weight mine (XL) when I receive it (should be in may). We have a RSD Middlechild and it's heavierFriend of mine had a Nimble 9 a few years ago. The frame alone is 8lbs. Don't know if that's good or bad for steel.
