BB386 EVO press fit cups removal
Any tools that will facilitate the removal of the BB386. EVO press fit bottom bracket. I installed Campagnolo Ultra Torque BB3866 86.5x46 press fit cups with Loctite 609 sealer and need to pop out the cups to reinstall. The Park BBT-90.3 tool is too small a diameter to punch out the cups.

You could just cant the Park tool a bit and rotate the tool around the cup while tapping. Or use a flat tip screw
driver as a driver, or better a long enough metal rod tapping around the inside perimeter of the cups to
extrude. Some punches are long enough but most are too short, with an alignment punch the best bet here.
Assumption that the cups will not be reused. If reuse is contemplated a 1/2 or 5/8" wood dowel might
work as well. A length of 1/2" copper pipe also is a possible driver.
