True to size, smooth rolling
These bearings measured true to size with a digital micrometer. I used them to replace the balls in a Dura-Ace 7400 rear hub and bottom bracket. Are they truly smoother than equivalent steel? Maybe, maybe not, but the psychological advantage is there and it's a cheap upgrade when repacking. Tigerdog sez: let's roll!

Works great as a substitute for SIC pearls.
I use them in a banger, and it works great, no need to use the same amount of money on 1 sic pearl when I can get 25 of these.
