Review on Shimano Tools Bottom Bracket TL FC33 by Rosalio Zavala

I recommend this instead of Park Tool BBT-19.2. The Park Tool teeth are shaped differently than the Shimano TL-FC33, and the round plastic adapter that comes with the new Shimano BB-R60 Ultegra 6800 (and Dura-Ace) bottom bracket will not fit the Park Tool. even if you try to score with a rubber mallet. So it's better to buy an original Shimano version instead, so you have a tool that can accept Shimano plastic adapters for the new type of bottom bracket. Note that this Shimano has a 1/2 inch drivetrain.
