Worked great, much better than the short lived noisy ES21 I replaced.

Be sure to remove your old bottom bracket and match up the correct size. If the diameter is off it won't fit at all, if the length is off ou may find your pedals no longer in the right place (including the crank gearing locations as well).

Seems to be a solid part. I bought it to replace the cheaper model (didn't know I had it 'till I pulled it). The cheaper model lasted easily 5-10,000 miles, including salty winter riding, so I expect this one will do well also.

I replace a cup and cone bottom bracket on my Diamondback Overdrive V (which according to specs was supposed to be a sealed cartridge like the BB-ES51)

What a difference! The ride is buttery smooth now. I love how easy it was to install with the Shimano Bottom Bracket Tool I also bought here on Amazon.

I'm using it with a Shimano Alivio Octalink crankset and love it. The ride is really nice.

I'm disappointed that the non-drive side cup is plastic. I can't imagine that that flimsy cup isn't going to disintegrate when you torque it down to the required torque specification. I found a metal cup from another Shimano bottom bracket (also on Amazon) that fit perfectly and used that instead.

I replaced the original bottom bracket on my 2011 Specialized Sirrus Comp with this one, since it is wider and allowed me to install a chain guard and still clear all gear shifting.
It was an unexpected surprise. Pedaling feels so good with it!

No issues way solid for me. Went from square taper to these . Torque your crank bolts a couple times to make sure they are set. I haven't had any back off issues.

There just isn't much to say about this bottom Bracket except it works good and lasts along time. Give it a try, the pricing is good and shipping is fast.
