Had a professional mount tire on wheel. It would not hold air. Suppose to be tubeless. Called Demon's Cycle and they refused to let me return it because I had a tire mounted. I told them that was the only way to find out if the wheel is any good. No response from the person I was talking to. PRODUCT IS A TOTAL PIECE OF CRAP! THEY DO NOT STAND BEHIND THEIR PRODUCTS. STAY AWAY FROM THIS COMPANY.
