Thanks JohnnyD.
Do these enduro bearings have a number or code ?
Yes, the link in my previous post will take you directly to the product page from the website.
I personally use the type 2 bearings on my bikes(they fit more than just my Super V as they also fit both of my Jekylls) but they aren't required. They were on sale when I got them so I bought the "upgraded" version. They number 1 priority is the dimensions (Inner x Outer x Width):17 mm x 30 mm x 7 mm which is an exact fit to what I had removed from the bike. The number I removed is a 6903 RS. (The RS stands for Rubber Seal) The LLB means the same thing.

For reference this is one of the original bearings I removed last year and are 31 years old. They are both just plain ABEC 3 steel bearings and held up fine for decades of use. In fact I just cleaned them up and applied fresh grease to keep them as emergency backups.
These are the what the enduro bearings look like
Standard ABEC 3 steel bearing (the full stainless looks the same but is made of stainless vs chromoly steel)
