I have started to make a list of the different bearings and what the industry standard number for each is since most of the bearings are standard metric bearings.

I will try and add more bearings in the future. I take no responsibility for the dimensions since I have not actually measured most of them myself but instead I rely on information derived from different websites. Please notify me if you find and errors

4305 and 5305 is basically the same bearing but 4305 is metric all the way with a width of 24mm and the 5305 is a "mixed" bearing with metric inner and outer diameter but exactly 1 inch wide. Since it's a metric bike and I live in Sweden I will probably use the 4305 instead of the 5305 and adjust the measurements for the spacer accordingly. The suffix 2RS indicates it has a rubber seal.

16005 was the suggested standard part number when I searched for the dimensions 47x25x8mm but I could be wrong. The 6005 seem to be almost exactly the same but 12mm wide.

Both are regular ball bearings
