I've bought two of these BBs. First one worked great, but had a plastic sleeve that came with it. The second one had a metal sleeve and one of the cups was out of round and compressed the bearing so it wouldn't spin well.I can't recomend this product.I would recomend buying a higher quality option if you want a hassle free install. But this is a budget option for the home mechanic that likes working on bikes.

Not the smoothest or stiffest BB, but it does it's job. No complaints. Fairly lightweight.
