I was going to put a King on my new bianchi when I was informed that I had a integrated unit.
What is my best aftermarket option for the cane creek unit?
there is a king integrated headset. i forget what it is called but you can see it in the king www site
FSA has two Cane Creek compatible integrated units...the Orbit IS and the Orbit IS Carbon.
Some Bianchi frames require the Cane Creek ZS (Zero Stack) headset. The bearings in the IS are directly in the (machined to accept them) head tube. ZS design uses cups which fit inside the head tube to accept the bearings.
