Yes. This is what I meant when I spoke about them being finished in a miniature nuclear reactor. I spoke to people in Japan back in March 2008 when they were first released, and to be honest the process explained was way above my head: Bombardment with carbon atoms in a pressurised vacuum chamber with gradual introduction of argon gas and such crazy stuff!! When I first fished it, my mates were joking that I should take it easy not to end up in a huge mushroom shaped cloud
Serious technological muscle flexing by Shimano there.
