Shimano BBR60 Ultegra BSA Bottom Bracket

Like all Shimano or Sram genuine components - it works, and works well.

I've been riding a lot this past year through some very wet New England weather. Although I'm pretty good about maintenance and making sure to dry off my bikes before putting them away, I started developing some annoying creaks in the drivetrain of my "do everything" steel gravel bike. After tightening and lubricating the pedals, crank, cassette, axels and chain, I was left with only one potential culprit, the BB. Fortunately, this model is inexpensive and a breeze to install. For such a cheap part, it really made a world of difference. My pedaling is now smooth and relatively silent again. Note that you will need a Hollowtech bottom bracket tool to do the install, which is unfortunately more expensive than the BB itself.

Easy to install. Came properly packaged. Very light.

I was setting up a Zwift setup for winter training and decided to pull an old bike down out of the garage rafters to give it a new life and the thorough going over. She was put to pasture once I became addicted to Di2, carbon EVERYTHING, disc brakes, and tubeless tires. On another tangent, I've forgotten how wonderful metal is as a frame material. The feeling and feedback is something that's gotten lost in the match towards "higher tech". This bike will now be the rotation again, once the weather warms and I purchase a set of tubeless wheels ...some tech advancements are just too good to ever go back. Ok, back to my BB review... The part arrived rather quickly and I hadn't finished putting on the new cable housing and cleaning/lubing the drivetrain so this was out on the back burner, since I wanted to get the Zwift sled up and running ASAP. In time I got the Zwift thing down and got the bike dialed in on the (Zwift) hub, so though now I had time to pop in the new bottom bracket. I knew the original Ultegra BB was ok and still turned smooth after 15 years and thousands and thousands of miles, but I bought this new BB on a whim when gathering up fresh parts for this project. I saw how Shimano claimed lighter weight and a 50% reduction in friction, but we know how "NEW AND IMPROVED!", sells so didn't buy too much into the hipe. I opened the box and thought I purchased the wrong part because the BB threaded shell looked WAY too small compared to the old one still in the bike 🤔 I fished around the box looking for the advertised adapter that's supposed to come with the BB so you can use your older took to install the new gen BB, but it was nowhere to be found, which is why I dinged the review on ease of install ... be warned, you'll likely not have the right tool to put it in if you're used to servicing your old BB. Once the correct tool arrived I swapped in this new one, put the bike back on the trainer and put on my kit for a ride. 🤯 I couldn't believe how much LESS energy it took to power the bike! Shimanos claims of friction reduction are not hyperbole. I could see it on in the Zwift data too, I put out fewer watts over the same courses I'd ridden several times. Data doesn't lie, this thing was a huge improvement in efficiency and you can see it in the data. To add to that, it cleans up the looks of the whole BB area and makes it look far more modern. In closing, even if you don't NEED a new BB you need this for the friction reduction and sleek looks and ... IT'S CHEAP!!! Get it, you won't regret it other than needing to buy the tool to install it if yours doesn't come with promised adapter! 👍🏽

Works great, keep in mind that you need a different BB tool to tighten if you're used to the older style Shimano and SRAM bottom brackets.

This BB is a perfect fit for a Dura Ace Hollowtech crank. No issues and with the correct tool, went on perfectly, comes with thread locker already applied and was heavily greased. Very well made as anything with Shimano always is. As a bonus, the anodized black contrasting against bare Ti is really nice.

Very smooth.

I'm always surprised how reasonably price these are, and I'm also always surprised how much I can feel the difference when I put in a new set, so if your cranks feel a little slow while you are lubing your chain, it's likely time for a new set.

Really easy to fit, just make sure you have the right tools at the start and lubrication for reassembly There are no special knacks for putting back together. The tightening direction is printed on the parts. Just take your time, work in a light and spacious area, I was in my kitchen I turned my bike upside down but a bike stand would have worked as well Good part. The previous one lasted 4000 miles. I am expecting the same or better from this

Zeer goed

Einbau hat gut funktioniert, Haltbarkeit muss sich zeigen, der Montageschlüssel beim Einbau war kleiner als der zum Ausbau des alten Holotechlagers.

As described, on time.

シールがしっかりされているので耐久性は一番良いと思います（耐水性） 回転性能は正直微妙です。 ひとつ言えば取り付け用のアダプタがなくなったのが残念
