Shimano Ultegra 6800 SM-BBR60 Bottom Bracket $29.95
Spin without the drag.
Shimano's new Ultegra 6800 SM-BBR60 Bottom Bracket was made with the same high level of precision that you've come to expect from the engineers at Shimano. The silky-smooth steel bearings, advanced sealing, and high manufacturing tolerances make the SM-BBR60 the perfect bottom bracket choice for either your English- or Italian-threaded frame.
The 6800 bottom bracket weighs in just around 76 grams, making it close to 15 grams lighter than its predecessor. In addition to the making the bottom bracket smaller and lighter, Shimano says that the design of the BBR60 reduces rotational friction by 50%. This is said to be due to advancements in Shimano's sealing technologies.
The Shimano Ultegra 6800 SM-BBR60 Bottom Bracket is available in one size and for either English (68mm) or Italian (70mm) threading.

- Familiarity: I've put it through the wringer
I bought one of these for routine replacement of my bottom bracket. Shimano alleges that the drag from the seals was 50% less etc.... I was surprised to find out when it was installed that it was noticeably easier to spin the cranks and even more so that it was noticeable during riding.
What is not clear is that all of the new Shimano bottom brackets are different sizes and require different tools to install. This is not spelled out clearly by Shimano although they do include a plastic insert that will fit the old size bottom bracket tool. This is not a great solution since the plastic wants to strip when you tighten the bottom bracket to the 35-40nm torque spec. So do be careful when tightening. An even better strategy would be to get the right tool. That also is not clear, but it is the BBT-59 from Park Tool - which I discovered after calling them directly.
Bottom line - I really like this bottom bracket and would recommend it.

I have a Tiagra Hollowtech II triple crankset currently using BB4600 (Tiagra) bottom bracket. When I service/replace the BB, can I use this one (BBR60) as an upgrade?

I have a 2013 Specialized Allez Compact that came with a Shimano bb un-26 68mm. Does the SM BBR60 have the same threading and will it fit my bike?
You would need a new crankset to use this BB. This BBR60 is for Shimano's Hollowtech-type crankset. From your description you have a square shafted crankset.

bought ultegra 6800 components, crank 175 53-39
witch botton braket do i need?
I believe the 2011 P3's utilize a standard 68mm English threaded bottom bracket. Since you are running the 6800 crankset, this SM-BBR60 in the "English" variant would be the way to go. The Italian version is a similar bottom bracket, but uses a different threading than what is used on your Cervelo.

Does the new Ultegra BBR60 come with the plastic "tool adaptor" so I can use my old external BB tool?
