Shimano Ultegra BB-6700 Bottom Bracket $0.00
These are the bearings and cups that thread into your frame for use with the Shimano Ultegra 6700 crankset. The bearings themselves will actually be outside of your frame, one reason why the 10-speed drivetrain rides with such sublime stiffness. This unit is compatible with both Double and Triple Ultegra cranksets. Available for either English (68) or Italian (70) threading.

Will this bb come with spacers to fit a 73mm shell?
Mine did not. The Ultegra BB is intended for 68mm or 70mm (depending upon which size you purchase). No sign of a 73mm Ultegra BB.

Where can I find the spec's on the BB of my BRIDGESTONE 400, so I can upgrade to the newer outside bearing BB?
Generally speaking, basically you need the size of the bb shell on the frame-68mm or 70mm. That will give you the thread size-68mm for english and 70mm italian. There are several ways to determine bb: 1)Remove the BB currently on the bike and it may have specs on it. 2)Measure the shell size (width) on your frame with a caliper (68 or 70mm). 3)99% of the time english bb are threaded opposite each other (one side-the non-drive side-tightens/loosens normally and the other side-drive side-tightens/loosens opposite) while italian bb are threaded normal (right-tight/left loose) on both sides. 4)Try a spare bb in english thread, if it works it's english, if the threads fall through, it's italian. 5)Italian is much rarer than english, but that is more nowadays. If going to external bb you may need a new crankset as well though-your old crank may not have a long enough spindle. Check here: http://sheldonbrown.com/gloss_bo-z.html#bottom.

Is this compatible with the 2009 Shimano Ultegra SL FC-6601/6650-G Crankset?
Yes, that will definitely work. Shimano has moved to all outboard bearing bottom brackets. This is standard.
