After several tries including using a 4ft steel pipe cheater bar I gave up removing drive side bottom bracket lockring. I got the non drive side after much sweating. This is a new mini I just got. Wanted to grease BB as they have a reputation of being very tight. Also this is a 2007 or 2008 new so has sat in warehouse a while. I was using the clockwise remove as the drive side lockring is usually left hand threads.I have the proper tool. Any advice or something else to try? I really want to remove and grease before this bike gets gooped up.
If 4 foot torque dont work , sounds like time to try and destroy the bottom bracket and create stress relief from the inside, you have allowed thread penetrator or ammonia to sit in BB shell from left side for some time? Clearly need to tap BB shell again after you do get it out. Frozen seat posts can have a similar issue as jur mentions , but this sounds like it may be time for those assemblers need to get away from the 1/2 drive air tools.
