Be Careful. There are two different bearings used to identify the 6205-2RS. This one has a bore diameter of 24.9mm and is listed as 25mm. If you're looking for the 6205-2RS with a 1" bore, this isn't it. Look for a list that specifically says 1" when you want one with a 1". Revane thinks they have them all are the same. I don't know why Revain is showing this item in the results as it is not listed as a 1" hole. It would be great if the seller could make that clear in the listing to avoid other potential problems and time wasters avoid.This is just a warning to other users about the size difference and does not reflect the quality of the stock or the seller.I will be happy to update this review once the description is clear enough that others don't make the same mistake.
