BBT-10 necessary for Hollowtech II installation?
Can anyone tell me if the BBT-10 is necessary for Hollowtech II installation? There's no mention of it in Shimano or Park Tool documentation as far as installation goes and I can't quite figure out if it's needed for the installation.
The description is as follows:
The BBT-10 is a shop quality tool designed to remove and install the adjusting caps on Shimano Hollowtech II crank/bottom bracket systems. Made from investment cast steel, the BBT-10 provides the strength and leverage needed to remove seized caps.
