WTD: straight steerer carbon disc fork for EC34 headset

These seem to be rare as hen's teeth. Looking for:

• clearance for at least 32c
  
• post-mount
  
• decently light (sub 700g or so)
  
• black
  
• quick release
  
• crown race suitable for EC34, so ideally ~30mm but could get away with up to 42mm
  
• at least 240mm steerer
  
  

Thanks!
