Cannondale Headset
 

Hello,
I just received a new headset for a CAAD10 project.
Two washers were included that I wasn't expecting.
I circled them in red.
I checked my other CAAD10 and it doesn't have the washers.
Just curious if anyone knows what they are used for.
Thanks,
Jan

They are thin spacers. You might need them (or not) to achieve proper preload on the headset bearings

Got it.
Thanks

If they're angled to match the conical frame sides of the bearings, then they're likely shims to raise the bearings, so the top cap has the right clearance with the frame. If the bearing settles in too deep, or the cone presses in more because the steerer is a bit small, the top cap will be lower, and may rub. OTOH, too high and you have a gap for dirt and rain to blow through.
