i emailed Cobb about a 2 yrs ago and he said still the fastest fork out there was the QR carbonaero----at that time the ouzo pro aero was around, now to my eyes, the profile ACD looks almost identical to the QR carbonaero----although i havent compared rakes, and dimensions of the blades. Isnt the Cervelo fork the Profile ACD?
I have the BDC fork on my 2000 Cervelo. I think it is a great fork, but it is very heavy. I am going to replace it before IM Lake Placid this year. Not sure if I will go with Reynolds Aero or Cervelo’s new fork when it is available.
