Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by Great price and FAST delivery! This item was dispatched from the UK on Monday and I received it in California on Friday. A beautiful crankset at a steal of a price. Count me as a regular customer. Very happy!! 17 December 2011
Rated 5 out of 5 by Bargain! Ridiculously low price for a quality item. With the extra discount offered, this works out at less than half price .... so I've ordered another one for winter bike as well. 01 December 2011
Rated 5 out of 5 by Lovely piece of kit as you'd expect from Ultegra. Very pleased with it. Not mentioned in the description but this includes the bottom bracket. 13 October 2011

Answer: 
The bottom bracket is not included with this chainset. You can fit it to a standard BSA 68/73mm shell, or a Shimano Press Fit shell as long as you use the correct bracket.
