Have the 2021 Merida e160 8000 and underneath the shaped headset spacer that the cables route through at the front of the headset there is an external plastic seal/washer that looks like its there to protect the bearings. Mine has split and looking for the part to replace it. Looking at the manual the headset is MERIDA/VP-8152 (MH-P16/ MH-P16) but searching for that all I get is the bearings. Can't find it on the merida website either. Anyone know what the part is (see pic) so I can order a replacement? Hopefully just a generic part?
