Questions & Answers

The Ultegra or the generic shimano bsa bb is cheaper, but does it perform better than any of the lower end shimano bsa bb?

These two bottom brackets are pretty much similar in terms of performance for the vast majority of riders. However, you may have even more to worry about if you are gearing up for the Tour de France.

What settings would I need to make this compatible with my current bb 'shimano dura-ace' The ACE 9000 bottom bracket is available as a small or medium size How about 'bb9000'?

That should be the case. It was a straightforward process to upgrade from 9000 to 9100.

The product is compatible with the Shimano 105 FC Is the R7000 crankset the right one?

The HOLLOWTECH II cranksets are all compatible with it

Selected User Reviews For SHIMANO Dura-Ace BB-R9100 Bottom Bracket

I found the installation process to be very simple

5/5

Installing Windows can be a piece of cake if you have the right tools. It still looked okay though I replaced Ultagra BB that had 12k on it, but Dura-core is a much better choice My guess is that Ace should be batter. YouTube videos will show you how to install it and save you some money on mechanics.

The fit is good

4/5

Bottom brackets using Shimano parts are notorious for having poor bearings in Trek bikes There were no problems installing this and since it is new, there was no noise when pedaling. It is also nice not to hear the clicking and crunching sounds. When I have driven a few miles, I will report back.

As of now, everything appears to be going smoothly

5/5

It eliminated the noise from the bottom bracket and made me 5 watts faster on the pedals, almost like a little hamster inside me.

I would give it a higher ranking

5/5

It is a great product at a great price, and it has less drag than a Chris King, and you not only discard it, but also don't bother to service it. It has 6k miles, and we haven't had any problems with the bearings. The outer cups are the same size as my BB shell, and it looks great.

Commute by loaded vehicle for up to 2500 miles each way

5/5

I have previously used this bottom bracket on two other projects. On average, I seem to get about 2500 to 3000 miles out of a set of tires. As long as it is installed correctly, it doesn't make any noise. I expect it to work.

I was satisfied with the outcome

4/5

I was pleased with how quickly the product arrived and how it worked. My bike has some Dura-Ace parts, so I appreciate that the converter allows the older tool to be used with the newer, smaller bracket size. It weighs 66g, and I am happy to report that I own some Dura-Ace parts. You're the best!.
