Yeah, the comment did reveal the guy has some serious issues. Most of the who come on and talk about "heavy" frames are kids or new riders who think ultra-light weight is the most important thing about a frame, as if saving a pound on the frame is going to make them a racer. The newest sub-1 kg CF frames certainly are amazing from a technical standpoint and fun to ride, but in the real world mean very little for performance.
People need to keep things in perspective. On big rides here, I normally carry two 24 oz water bottles (3 lbs of fluids) which weigh slightly more than my frame. I've experienced a "negative weight" frame just by leaving those at home.....and it's a bit sad to see how little difference this makes climbing speed up my home hill.
And all this is before counting the 20 extra lbs of bodyweight I've got this season.....that's like carrying 6 extra "heavy" ti frames
