This product was purchased because it is the reccommended bottom bracket for the the Alivio crankset that I reviewed earlier. I've read in some of the customer reviews that this product fails under heavy use. That really wasn't a concern of mine as my bike isn't ever subjected to heavy use. I use it mostly for short trips within my neighborhood. This BB is very smooth and it's easy to install if you have the proper tool. It's a perfect fit for what I use it for. It's also priced right.

3.0 out of 5 stars ok bottom bracket but not for off road, April 4, 2011

this BB is fine for onroad and light off road but it may be worth the extra 8 bucks for the UN54 which runs much smoother and is by far stonger.

I bought this bottom bracket as a replacement for original equipment on a Diamondback mountain bike. I noticed that despite my effort to match the dimensions, the bottom bracket wouldn't thread fully into the bike but I don't fault the product for that and in any case functionally it works just fine.

The action of the bottom bracket is very smooth. The plastic cup included with the product got a bit beat up as I tried to install it, so I ended up keeping the original metal cup from the original equipment bottom bracket. I would have preferred a metal cup.

Overall, based on the Shimano brand and reasonable price, I would purchase the item again and so far it is performing well.
