It's actually a Bridgestone X0-1 so it's a 1" threaded fork. I installed a Chris King headset and scuffed it up a bit in the process so I'm weary of using a headset mounted cable stop...the stem with built in stop is actually a good choice but I already splurged on a nice new technomic stem that fits excellent so that's out. What I meant before about the fork being threaded...the bolt hole in the fork crown used for road calipers is actually threaded...weird. Don't really know what Grant was thinking on that one. Maybe it does have a practical use...but I certainly have no effing idea what that might be! Anybody out there have any thoughts on that?
