I would recommend that you pop them out and check measurements.
Steel 6000-2RS bearings are about £1 each and stainless steel about £2.50 each.
No point going ceramic if it is for a daily ride. And you will need Rubber Seals if it isn't an indoor track wheel as otherwise grit will go into them.
If you are at a loose end, I always have a couple of spare steel 6000-2RS in my parts box...
Also, while I'm here, had a good old clean of my wheel and the bearings had 6000lu tp1 436 stamped on them.
What do I need to search to replace them? Will any 6000 series, single seal bearing work? The ones above look ok, albeit expensive...
