Review on Park Tool Bottom Bracket 32Mm by Jonathan Olson

I am repairing 3 mountain bikes in my family. I needed this to remove the Shimano bottom bracket cartridge. It's good to use this to take it out from time to time and clean any rust or dirt in the bottom bracket. Note that some manufacturers fit a red Loctite cartridge, so sometimes you need a large wrench. Also, I used a foot pedal bolt with a washer to hold it in place so it wouldn't slip out if I had to put VERY hard pressure on it to loosen the Loctite. When reinstalling, use the blue one so that when you service again after 6-12 months, when you try to remove the crank cartridge again, the vein will not rupture.
