i appreciate everything you all have to say. I have been using ultralight wheels on my bikes for many, many years, although not this light. It is possible this wheel could fail in some way. I don't want to crash ever again, I have had many, many crashes in over 40 years of riding, but never due to some part failing. This is not an every day wheel, and hitting a bigger pot hole at speed would not be good. But overall this wheel is strong enough for my 140 lbs. With all of my 16 and 18 spoke wheels I always carry an extra spoke with me because when a spoke does fail, even after adjusting the wheel, a 16 spoke wheel is still somewhat out of true and round. This M5 hub is not the most durable but I have used it for years, though not a lot of miles on it, I don't for see any problems with it causing a crash. The carbon rim, even at 186 grams, I really don't forsee a problem that would cause a crash. The Pillar Ti spokes are not the strongest but I have even spoke tension and even with only 16 spokes I don't need high tension. This is weight weenies, I'm a weight weenie, and even when my wife says I'm crazy, I just have a real "feel" for what I can do. Again, this is not an everyday wheel.
Mine failed at the seam. I was 130-135 at the time.. but the rim wasn't carbon so you have that going for you. It started out with a funny sound.. thinking the tire was going flat I gently hopped the back then the front to feel if there as a pressure loss. It failed when I checked the front.
Just keep checking em and good luck! Will look forward to seeing the total bike weight.
