Review on 🔧 Efficiently Service Your Bottom Bracket with the Park Tool BBT-9 Tool by Brian Vasquez

Great tool, although I've found over the years that it's too big to fit certain frames and requires rotating at an angle , making it likely to tear off bb grooves . This is because they use cheaper metal (making this tool relatively cheap, so not a bad idea actually) and are therefore oversized. For example RWC GXP BB + SantaCruz Tall Tower => You'll need to remove the frame's rear triangle to fit the non-drive side, or crank it up to 50Nm (which is pretty much a guarantee of cleaning up some of the bottom bracket grooves)
