Hopefully a simple question. I have lost one of my plastic bearing covers (pushes in and has a v small hole in the middle that the grease squirts out of when you grease the bearing). It is a Hallmark Coaster 3 trailer and the diameter of the lip that pushes in is a tad under 5cm.
Any ideas where I can get a new one or should I fit bearing savers.
Advice welcomed - thanks.
