My Wilier has a stuck right cup BB. At the moment the cranks spin
fine. It has an FSA Mega Exp crankset that is the one that is not
pinch bolts but uses self extracting allen key to put on drive side
crank arm. Has the wavy washer in the set up. I think that is why
the bearings went bad because it allows moisture to get in not
sealed like a regular shimano crank and external BB.

The BB is of course and external BB from FSA. The let side cup
bearings went bad so I used a Shimano BB60
Do NOT cut any bottom bracket! The left and right hand threads unscrew
FORWARD which means counterclockwise for the left hand and clockwise for
the right side.
If you cannor loosen the BB and have stripped the grooves for the holder,
get a pair of lock jaw pliers and lock them tightly to the BB that cannot
be squashed with the bearing in place. Then get an 18 inch pile that will
bit over the handle. That will free ANY aluminum on aluminum joint. Before
sawing anything off you might as well throw the frame away. Andrew could
probably save it but most shops wouldn't have the proper tools.
