Review on Park Tool BBT 18 Bottom Bracket by Brian Page

It would be great if you could fit a socket or torque wrench directly into this tool, but don't bother with an unusually large head either a 36mm or XL adjustable wrench. I first tried a tubular wrench (because I had one) and it was so awkward applying any torque to keep it from slipping off that I figured an Allen wrench was the only way out. That and the impact wrench did the trick. Remember: On the right side of the bike, the threads are reversed (turn clockwise to loosen).
