That's a really good weight. I would be a weener and ask if you are gonna go sub21 in the future, but I'm probably not going to bother setting the bike up at sub20..... sooo
but the blue is special edition! and i have them, and the bars, and the seatpost. all in the special edition blue. you can get a ti axle kit for the neutrons and that'll drop you a few hundred grams
Sorry man, but I'm not about to believe that an amp with average spec is 21.3lbs without proof. The fact that on one of your ads you said it was 23.5 doesn't help. For your build 23.5 would be a fairly reasonable claim.
