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