Nothing to say but everything is as described and pictured. The bearings are 1/4" and 9 in each ring. 10 rings will be assembled as shown in the picture. I expect 8 of them to go to waste but I'll stick with them who knows. I use regular automotive high temp high speed bearing grease to fill them up. For the small number of rides I do this is the last set of bearings I need. I left the old ones beached for a couple of years with occasional salt water treatment and no maintenance. Rides very smooth now , nothing squeaks or squeaks can't speak about durability they are new and may never need much handling but then again I still have 8th sprockets and drive axle I have traveled a lot and my sprockets were very worn It's enough that the chain jumps when it rests heavily on them.
