Required is a 1" threaded steerer that is at least 8" long with threads extending to within 6.5" of the lower Race. And of course the associated headset and crazy nice handlebars depicted above. Got just the bars-Cool! Just the Fork-Fine
I have a Dia-Compe Bull Dog for the front brake or I also have the Shimano Deore BR MC 70 brakes if the Fork is set up for that style of brake...
