Every little bit counts.

Shimano's 6800-series Bottom Bracket drops 14 grams off its predecessor thanks to its new slimmed down cups. Redesigned seals dramatically reduce drag, eliminating friction by up to 50%, while keeping out water and debris.

The SM-BBR60 is available with English or Italian threads. It's compatible with all HollowTech II cranks and weighs 77 grams.

Note: The SM-BBR60 features a slightly smaller spline diameter than a typical Shimano bottom bracket cup. An adapter is included for use with standard Hollowtech II-compatible bottom bracket tools. It can also be installed and removed using the Park Tool BBT-29 Bottom Bracket tool.

Bought this to replace my 5 year old bottom bracket on my Bianchi. This bracket is very reasonably priced, it's light and easy to install.

Works Well, easy to install

I am a fan of this style BB and wish all of my bikes had a threaded shell. Simple, straightforward installation, and quite economical. This is a noticeable upgrade to the previous 6700 BB that had a lot of bearing tension on the spindle, this unit spins much easier. I would give 4 stars but that durability was an issue previously and unknown with this new unit. However, with the reduced bearing tension I do expect that it will last much longer.

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

It works great and looks great

This shimano bottom bracket simply works, and looks great. Even comes pre-greased at the bearing interface, ready for you to install your crankset.

I had similar issues with the tool adapter, specifically using it with the park tool BB total. it was a tight fit tool-to-tool, but it works. In contrast to other review, I was able to get it plenty tight by being careful.

Proper Tool

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