Bottom bracket tool for Shimano BB-R60 Ultegra 6800/105 5800 Hollowtech ii?
The Park BBT-59 is the main one you'll see. (If you scroll down a little on your link to it, you'll see it says it's the one for BBR60.) A less expensive one from Lifu/Icetoolz now exists and I see it can be found on ebay if you search for "icetoolz m093." It's 1/2in drive.
