|Integrated Headset Installation||hudsonite|

|I am building up a new Look 381i (Carbon fork and steerer). Everything is going well, but I have an open issue with the install of the integrated headset.
The package for the FSA headset includes everything that I would expect:
Upper and lower bearings
Upper compression ring
Cap and plug
Collection of Carbon spacers
The problem I have is that there are 4 aluminum rings that are exactly the same size as the carbon spacers, but very thin (.3mm). I have no idea what these are used for. The instruction manual does not mention them and I cannot see the use of them. The rings are stamped with the name of the manufacturer of the bearings.
Any idea what these are used for?
Thanks for your help

|If the FSA headset is anything like the Cane Creek, these spacers are likely to be used between the upper compression ring and the cover. On some headtubes, the cover will rub on the top of the headtube unless a small spacer is used above the upper compression ring.
If you assemble it all and the bearing cover does not rub on the headtube then I think you will be fine.

|this thread has been dead for a while, but I found the answer yesterday. I am posting this because someone will have this question in the future. Hope this saves someone some grief.
The Carbon cap that goes over the top bearings needs to have a .5mm clearance to the head tube. These thin washers are used to increase the space between the cap and the headtube.
Without the washer/spacer, my clearance is .45mm. I am going to leave it for now.
