Shimano 105 BB-5500 Bottom Bracket
As a direct descendent of Dura-Ace, no other road component group provides the same cost-performance value as Shimano 105.
The Octalink V1 8-spline interface between the BB and crank arm forms a strong highly rigid connection that reduces weight and increases strength.

The unfortunate thing about these bottom brackets is they do not last. I have to buy a new one basically every year because they develop play in them, and there is no adjustability - which is unfortunate, because even the really cheap Shimano LP-20 BB's are even adjustable/rebuildable. I used to be able to get this exact same 5500 bottom bracket for just $29 here on Jenson (just went and looked at my Jenson order history), but I guess because they are becoming rare and people need them, they can charge more.
Having to spend $50 every year on a new bottom bracket is a bit unrealistic. At that price you may be better off buying a new crankset with outboard BB's (cheap options are Shimano Sora which supports 9spd - since anyone needing this has 9spd, or even FSA Gossamir cranks).
I have not decided what I am going to do yet, because the idea of buying another one at this price is disheartening).
PROS: Smooth, Comfortable, Attractive Design
CONS: Not Serviceable, Flimsy Construction, Wears Quickly
BEST USES: Commuting, Road Biking
