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.

  • Compatibility: V-1, 8 spline spindle for Shimano road cranks only

Comments about Shimano 105 BB-5500 Bottom Bracket:

Because v1 Octalink has been discontinued, Shimano is only making this one 5500 (105 level) v1 Octalink bottom bracket to support all the v1 Octalink cranksets out there in the market still being used. So the 6600 (Ultegra) bottom bracket and 7700 (Dura Ace) bottom bracket are both discontinued.

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).
