After getting to grips in recent years with all the types of headset standards I have now come a cropper. My new focus bike has some metal cups pressed in the headtube,then sit loose ball bearings then a metal seal. Followed by a oval spring clip.what is this type of headset called.the bearings are knacked and worse still the metal cups that bearings sit in are heavily pitted after 2 months.whatever it is this is the worst design I have ever seen.
