I know it's been done to death, but a lot has changed (maybe?) since the last one.
My gf has been riding the iro group buy as an every day beater since it first shipped a couple of years ago.
Her nice track bike has a bladed profile design fork and carbon bars (all threadless, of course); she knows the difference is huge, and has decided to go carbon on her iro.
Unfortunately, it's built up nicely as a threadless bike: ultegra headset, cinelli XE stem, etc.
I ride a pretty nice mizuno myself, but they're impossible to find lately.
Can anyone recommend a carbon threaded fork?
