Doesnt really look like a crack to me but it does look strange. I wouldnt worry about it. It's on the bottom of the mount and there is plenty of meat there. You'll be fine
It depends on which wheelset I have on, and what tires. DH casings are my preference. I will do a comparison and get back to you.
Thanks!
Sorry it took so long to get back to you on this question, I weighted it today with the Hope wheels and the Michelins ( I do have a tube with some sealant in the front right now ), it came in at 15.7 kg thats 34,6 pounds. With full DH casings from Schwalbe it goes to 36 lbs.
I'm guessing he meant for people that are under NDA on the new bike. I am not under embargo but according to the message I got on instagram "I'm not making any friends" lol
