Thanks for all the input! Since its a custom fork I can choose whether the steerer tube is threaded or theadless, and how tall it is. At this point I decided to go threadless, to get the max compatablity with my other bike. That bike takes a 1 1/8 headtube and this bike a 1", but I noticed chris king sells a devolution headset I could install on the other bike to allow it to accept a 1" threadless steerer tube if I needed to install the new fork on that bike for any reason (rake is identical). I only worry about stuff like this cuz these are 24" forks which are hard to come by so having max flexiblity is good. My experience also tells me that packing of the threadless system will be easier since I can get a pop top threadless stem but not threaded that is the right size. I am not sure threadless will be lighter in my case since I will need a longer steerer tube with the threadless system, but it might be which is always good. I shipped my frame to the builder on monday, and we will discuss the final details once he sees it, but at this point I think threadless is the way to go unless he sees a problem with this when he sees the bike.
