Great bottom bracket, a nice improvement from my worn out Ultegra bottom bracket.
Get this and not the 6800!! It "feels" better and last longer. I have bought two so far and both run them over 8000km
This may sound like an overstatement, but this BB has changed me in some way. I've never had a really nice BB before, never thought I needed it. But I decided to spend the extra 10 or 15 and try the dura ace. I can't believe how much more smoothly the cranks turn
Great price for a terrific product, second DA 9000 BB and it is a great product.
Smooth, creak-less
Comes with a bottom bracket tool converter for last generation bottom bracket tools. Easy to fit, light and inexpensive. Arrived very quickly - Merlin are the guys I go to when I want things quickly!
I was surprised how light it was, only time will tell if its long wearing and robust. But it Shimano and Dura ace so it should be!
I changed the stock bottom bracket on my Specialized Allez Sport, this runs much more smooth and fits like a glove. Perfect product so far. The included plastic adators made it easy to mount with old tools.
Replaced a 105 BB with this DA. Bit of a frivolous upgrade for me and I'm not sure if it's in my head but it does feel smoother (admittedly only smoother than my 105 with 4000+ miles on it). Fitting was a small issue as the smaller cups mean using the included adapter. My IceTools HT2 BB tool must have slightly off tolerances because the adapter didn't fit. Serves me right for using cheap tools, I suppose. Had to replace the tool and after that it fit wonderfully and was a doddle to fit.
A lot better than I expected. I was expecting the BB to be the same as the previous version's but finished in black. To my surprise it is a lot lighter, smaller and so far appears to do the job better.
This bottom bracket is incredibly light. Who would have thought that a bottom bracket could be improved so much, but this one is a significant improvement over Dura Ace 7900. Merlin service is great as well.
This is a really nice BB. So light and compact, and looks really neat fitted. The adapter tool works with the standard diameter bottom bracket tool and fits really snuggly, making it a joy to fit.
