this might be heading off topic a bit, if so sorry i don't want to hijack the thread.
i just had a wheel built with a 36h phil wood hub and deep v rims. I kept reading how they were both strong but heavy. From what i could tell it was lighter than the stock wheel it replaced on my khs flight100. Not dramatically, like half the weight, but enough that holding both i could tell the difference. I never had a super light bike so i might not know the difference.
I thought i would mention it if someone is searching on here for research and was worried about weight.
