StarStarStarStarStar Fantastic "bang" for the buck!

Pros

A lot of quality and technology for the price. Rotates with precision smoothness. Bearings seem awesome. In my hand, this feels as good as a Phil Wood or Chris King.

Cons

Although it looks and feels as good as a Phil Wood or Chris King (which are waaaaay more expensive), it probably isn't. However, I could replace this many times before I'd spend anywhere near as much money as they cost.

Other Thoughts

The name says "Shimano" which means it's decently good. Most likely, the production numbers of these are way higher than the uber-expensive alternatives....so I think that boils down to a quality product at a decent price that provides a lotta bang for the buck.

I've had mine for a year and put about 5000 miles on it and it's as smooth and "wiggle-free" as it was 5000 miles ago.

Loosened up a few weeks after first installation. This problem was solved with application of Loctite Blue Medium Strength Threadlocker.

Pros

Great price on a good quality bottom bracket.

Cons

It's a bit heavy but for the price and quality who cares.

Other Thoughts

I purchased this as an upgrade for a dept store 29er. I have ridden this bike a lot since I installed this bb without any problems with it.
