The Little Things
- I've put it through the wringer
- True to size
- 6` 0"
- 195.00 lbs
Sometimes the little things can make a big difference. In our sport millimeters matter. I changed out my bottom bracket, not due to any specific need, but just the itch to do right by my trusty steed. With that, I upgraded from a Shimano Ultegra BB to the Dura-Ace. The project in and of itself was very straight forward. Components came out and went in smooth as butter... Winter weather is upon us in MD and the bike has been committed to the Hammer trainer until further notice. (Crap roads+wintry mix weather+poor roads=NO THANK YOU!) Been really enjoying some serious SufferFest workouts, and this bottom bracket is getting a serious breaking in period. It's fantastic! It feels as smooth as can be and those NM workouts are having me put some serious watts through those cranks. Nothing of note to report aside from utter satisfaction. A nice upgrade for an insignificant cost. I enjoy doing my own wrenching, so this was fantastic buy!

Installed properly, smooth
- I've used it several times
Got this to replace an old Ultegra bottom bracket for an Ultegra crank because of crinkly creaking during hard pedaling. Would have be fine with another Ultregra bottom bracket, but out of stock. Threaded into my Pinarello F8 bottom bracket properly, tightened up and torqued in as expected. Cranks installed as expected and spin smoothly. Creaking during hard pedaling went away. Have had it on for about 300 miles so far. Pretty cheap solution, and now I've got some Dura Ace on the bike!

Is this compatible with all Hollowtech cranksets? - particularly Ultegra 6800?

Does the 9100 bottom bracket work with a 9000 series crank?

Does it come with the Dura Ace tool insert?

Will this bb work with a DA 7800 crank replacing a BC1 37x24?
August 24, 2019
It should. As long as the spindle is 24mm which I believe it is.

I have the Park Tool BBT-9, BBT-59, & BBT-69.2. Will any of these work, or if I need another special tool or adapter, which one?

Hey Chris! You'll want the BBT-9 for this particular BB. Be sure to let me know if you have any more questions! Thanks!

Great improvement for a few bucks, pedaling feeling is smoother than tiagra/105 model, just check compatibility with your frame and crankset, since this is laser cut, it could not fit your frame, the guys at my local bike shop had to use teflon but they pulled it off

I'm confused. How does this differ from the BB9000?

Will this BB fit a dogma f8 with dura ace 9100 crankset. Thanks.
