Headbadge Rivets (set of 2)
These are the fasteners that hold your headbadge to the frame. They're not actually rivets in the traditional sense. In rare cases, they're a bit long, so you need to break off the rest that's inside with a slotted screwdriver (or it'll rub on the steertube). They install easily with a hammer - just tap ‘em in. The frame holes should be very slightly smaller than the fastener diameter.
