'Good' bottom brackets
I was looking to perhaps change my bottom bracket which is currently a 4500 Tiagra to something better. Any ideas?
What makes a good bottom bracket besides weight, smoothness and stiffness(?)

Save your cash. Don't replace it till it's broken.

With few exceptions, current bottom brackets are maintenance items like chains. You ride it until it wears out, then you toss it and put in a new relatively cheap one. About the only exceptions are (1) bottom brackets with ceramic bearings which are too expensive to trash; and (2) Chris King units which are designed to be cleaned, regreased and reused. I got a Chris King model to replace my worn out Shimano BB. It has the usual impeccable Chris King quality and is just smooth as butter without much resistance. On the other hand, it cost 4x or more what a Dura Ace disposable BB would cost, so it really does fall into the Bike Bling category.

I wonder though, how much the smoothness really does for the ride. Oh well, we'll see when i have to change it.
