Gap between lower headset cup and fork. Is this likely to be a problem?
There is a part missing, commonly the gap is filled with a simple plastic ring which works ok as a seal. Either this wasn’t supplied with the headset, or was lost by someone before it could be installed. If I had a headset without this seal, I wouldn’t be surprised if it wore prematurely as extra dirt got in.
Seen in the bottom left of a photo of the current model is the missing ring which would seal the gap.
