It’s rumored that the new Dura-Ace 9000 Bottom Bracket is made of plutonium, to make your bike nuclear powered. “Is that true?!” I don’t know, but you probably shouldn’t believe everything you read on the internet. Made with outside positioned bearings for better weight distribution and more stability, the new 9000 Bottom Bracket has smaller bearings than the current model, giving it a lighter weight.
New improved sealing ensures 50% less drag
Available for conventional and Press-Fit applications
