Improvement over old version

I replaced my old Ultegra bottom bracket with this new 6800 version. There was substantial engineering effort put into this to decrease the drag from the seals. It's noticeably smoother and easier to pedal.

Do note that Shimano now has three different sizes of bottom brackets so you'll need the right tool for each. DA 9000 is the smallest in diameter, then Ultegra then 105 and none of them are the same size as the old outer diameter. Shimano includes a plastic adaptor with each bottom bracket to fit the old size Shimano tools (from Park or others). However, when you try and torque it down to the required 35nm or so, it's very easy to strip the plastic adaptor. Plan on getting the right tool ASAP. For this bottom bracket the right tool from Park Tool is the BBT-59.

Anyhow, this is a great deal in a BB in terms of cost and performance.

You are correct, these require the proper size tool adapter, which Shimano includes with their bottom bracket cups. We strongly suggest using great care and a high quality torque wrench to ensure proper care for the bottom bracket cups and the included tool adapter. Thanks for your feedback. -Thomas

Proper Tool

BBT-59 is the installation tool to use. Shimano's included tool strips out before the BB is torqued properly.
