These don't come out of the mould smooth, they're ribbed and need some significant sanding before they slot into the hubs. I'd call it a manufacturing defect, but I bought two packs and all of the rings are like that. You have to bang or press them into the hubs with some force - so forget ever taking them out again without destroying them or the hubs. I wouldn't buy them again.
Great race suit, second purchase as first suit fitted my grandson, so need another one for myself, Raised as bit of a family laugh when I mentioned my 75year old body was the same as my 17 year old grandson thou.
