Advice please re removal of drive side cup from Vitus frame
A couple of weeks ago, I picked up an old Vitus in order to harvest the 7400 DA parts. The drive side cup, however, is seriously stuck. Both the mech at the LBS and I exerted some very serious effort trying to break it free.
How do you suggest I proceed. I assume ammonia is out since the frame and BB are Alu.
Thanks
