9000 cassettes received a Shimano stealth "upgrade" in early June that added a second rivet point between the largest cogs and the carbon carrier.
Well, mine's been through National Champ 24, 12 and a bunch of training for them last year and is still going strong enough this year to bust out a 293mi 12hr. I've just bought another one 11-28 though for climbing. What is the extra rivet point for?
