Lay out the facts on paper then.
and anyone’s 7.5lb framed bike too.
OK, this is 30.1 lbs. Cotic Hemlock (somewhere between 6.5 and 7lbs with the latest rear end), coil u-turn Lyriks, easton carbon dh bars, pro FRS stem, XTR cranks, double chainrings with a E13 bashring and Blackspire Stinger, X9 shifters and rear mech (medium), SLX double front shifter, SLX cassette, cheap chain, Formula Oro brakes (203mm front, 160mm rear) Roval Traversee wheels, Kenda Nevegal 2.35 front tyre, Nobby Nic 2.25 Evo rear, Charge Knife saddle, and the clincher- gravity dropper seatpost.
So fit a standard seatpost or a 150mm Revelation or even a Float 36 and you’re sub 30lbs with weight to spare. No unobtanium, plenty of places you could lose weight in there. Strong like ox. The wheels are as light as you’re likely to put on a Mega but a couple of hundred more grams gets you Crossmax SX or similiar.
