Shimano Dura-Ace 9000 Bottom Bracket

Shimano’s updated their outboard and press fit bottom brackets, too. The bearings inside are smaller and the actual size of the external cup is smaller and lighter. The biggest improvement is in the sealing. They’re able to maintain the same sealing but with 50% of the resistance.

“For us, we believe that steel is the optimal material for the spindle and BB30 is really optimized for an alloy spindle and carbon crankarm,” said Lawrence. “We’re pretty committed to steel and aluminum arms and the 24mm spindle in steel is the best solution for us.”

Features:

  • Bottom bracket has smaller, bearings than current model for lightweight. New improved sealing ensures 50% less drag.
  • Available for conventional and Press-Fit applications
  • Outside positioned bearings for better weight distribution and more stability.

Buy Shimano Dura-Ace 9000 Bottom Bracket from Chain Reaction Cycles, the world's largest online bicycle store.

  • Size: 68mm

Rated 5 out of 5 by Good upgrade from stock BB of Tern Verge P18 Able to feel the improvement immediately after the upgrade. The new BB is so much smoother than the stock BB from Tern Verge P18. 09 March 2014
Rated 5 out of 5 by great piece of kit I was a bit surprised when this BB arrived ,but what a difference from my Hope ceramic bottom bracket. My Bianchi 928l now runs like it should,quick smooth and very fast. Would recommend this as an upgrade for anybody wanting to improve the smooth running of your drive train. 10 November 2013
Rated 5 out of 5 by Excellent and looks great being smaller I replaced my 7800 BB with this new one as i also changed to a carbon fibre crankset and this BB spins nice and also looks the part with the smaller bearing cups. I hope they bring out an Ultegra version now so i can change my winter trainer to the smaller cups as the larger cups look a bit cumbersone in comparison. 10 April 2013

Answers

Answer: 
Yes this is correct, FSA Uses Mega-Exo while Shimano use Hollowtech.

Both these spindles are 24mm but, the seals on the Mega-Exo Bottom Bracket are larger than what are found on the Hollowtech Bottom Brackets so you are recommeded to stick Brand to Brand.

Answer: 
Unfortunately you cannot use Shimano Hollowtech II style of BB’s with SRAM chainsets that have a GXP Spindle. You need to use a SRAM GXP BB or a Bottom Bracket converted to suit GXP spindles.

Answers

Answer: 
Yes, this should be ok to use with the CX70 chainset. The bottom bracket suggested for the CX70 is the BB-6700 (linked below), and this BB9000 runs a smaller external diameter of bearing and cup, but internal diameter and width is the same so they should fit fine.
