Review on FSA Threadless Headset Silver XTE1663 by Michael Onwukaife

Looks like JIS for big Chinese stores. On my calipers, the outer diameter of the cup insert was 30.08mm. It comes with a star nut. On a 2002 LeMond steel frame (Reynolds 853) I had to slightly gouge the inside of the head tube to ensure the use of a pressing tool. because it could be pulled out by hand without gouging. It worked for me, but I would prefer common standards to avoid surprises.
