I have this FSA BB that is stuck on the drive side cup. That would be a reverse threaded external BB.

I have tried the usual BB tool but it will not budge and I chewed the outside of the notches trying. So now my thought is get a hose clamp and put it around the BB cup. Then get it really tight. Then take a large pipe wrench and set it up to grab the clamp threading as a point of pressure and give it the big turn.

What do you thing of this idea. I don't try getting some penetrating oil in around too much work. I just want to give this one big swipe with the pipe wrench. If the frame goes south doesn't matter.

Good point.
The Habaneros are all BSC.  The early Italian built LeMond maybe not but Lemonds that I've worked on were BSC.

No a modern BSA threaded BB and FSA BB bracket with external bearings. It is reverse threaded. I tried my 8 inch pipe wrench but it would not grip real good and slipping. I think I need and bigger pipe wrench. I could cut it out but how is the is the next thought? Pull the crank and put a hacksaw in the BB. I would need to take blade and run it through the BB and attach and then saw?
