I had one of these, but it was a bugger to get a 38mm rake carbon fork to replace the aluminium original. With the angles being 74/74 it would rather twitchy with an incorrect fork.
I sold mine on here for £125.
I have no idea to be honest. All i know is that when i build it in order to test it felt very steady. My only problem was the size of the frame.
But you are right, from what i have read in forums people prefer to use aluminum forks with this frame.
