Worked great!
I’m turning my road bike into a gravel bike and wanted to update to a hollowtech and with a new single speed crankset. This fits my road bike! It comes with spacers to fit the extra room. Snug and well made

Great value
Works great. Threaded into my bsa bottom bracket perfectly and my 24mm hollow crank spins freely. I don't notice any creaking/grinding and the bearings are holding up well after a few months.

Shimano quality and reliablity
You simply can not go wrong with any Shimano branded bike parts. This BB is easy to install and the bearings are of very high quality. I have nearly 10K miles on my current BB and it is not even beginning to show signs of wear. Very durable and smooth spinning.

Still good, but Shimano quality has declined in recent years
Why did you pick this product vs others?: I've gotten good mileage out of a few of these. (10000 miles or so). Despite having smaller bearings than lower tiers, they have more of them, and I think that trade off in surface area increases longevity. They are not, however, as good as they used to be. I had DA bottom brackets from earlier generations that lasted forever under pretty harsh riding. These are good, but clearly Shimano has sacrificed longevity for other demands like weight or price. I also caution against buying these from sellers you don't recognize. There are a lot of Shimano knock-offs out there.

I use this product in my bike, before it make an annoying noise, now it become silent when pedalling and too smooth. I recommend to buy it.

Sealed bearing was a plus for me. Came in pre greased. Fits my wifes old mtb. Before buying would suggest to insure the size & specs match.
