Heavy.
Mine was expensive when I bought it. Can be had on the cheap now due to new versions

Review
This is a good bottom bracket, but I would pass it up for the x-type external bearings. The bearings are bigger therefore stronger. The x-type cranks also do not require a tool to pull them off.
Pros
The solidity of it, and the smoothness.
Cons
None really, its just somewaht different from other BB's in the same class as itself.
Review
Great for anyone who needs a real heavy-duty BB.
