Shimano 105 BB-5500 Bottom Bracket

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.

Shimano 105 BB-5500 Bottom Bracket Specifications

  • Material: Hollow chromoly splined spindle with alloy non-drive side cup
  • Weight: 250g
  • Compatibility: V-1, 8 spline spindle for Shimano road cranks only
  • Two Sizes: 109.5 Spindle for double cranks; 118 for triple cranks

Note: crank arm fixing bolts not included.

Road 105 grade Octalink BB
Recently Octalink isn't for the race, but 105 grade BB is still produced. Not so expensive as Dura Ace, not so fragile as BB-ES300 with plastic left cup, this is a good choice. Made in Indonesia, Shimano quality.

PROS: Durable

works for me
Stock bottom bracket on my 2002 Trek 520 touring bike which I bought used. I've put about five or six thousand miles on the bb now without any signs of bearing failure. I have no idea how many miles the original owner put on the bb. While it doesn't have the advantage of a Hollowtech2 system (replaceable bearings) it does have better seals than an outboard style bearing would. The downside to Octalink is that while the spindle is larger than square taper (for increased stiffness) this also requires that the bearings be smaller due to space constraints which theoretically results in shorter bearing life. Not sure what is inside the cartridge (I've read that it's needle bearings) but I've been perfectly happy with the longevity of the product. For the other poster, the reported early failure must be due to riding style or possibly some other issue.

PROS: Innovated Design, Good Crank Arm Engagement, Spindle Size Stiffness, Durable, Attractive Design, Innovative Design

CONS: Limited Stock, Relatively Small Bearings, Obsolete, Non Serviceable Bearings

V-1 Spline works with my Ultegra crank
Needed to replace my Ultegra BB and finding those are like looking for unicorns. The 105 is just a tiny bit heavier ( about 1/2 glass of beer at most ). It seems to be a little rougher than the Ultegra, but maybe it just needs some miles to wear in.

PROS: Worked With My Ultegra

CONS: Slightly Rough

BEST USES: Replacement Bb, Road Biking

CONS: Its Shows Made In Japan, Part Made In Indonesia

Does not last, huge price increase
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).

PROS: Smooth, Comfortable, Attractive Design

CONS: Not Serviceable, Flimsy Construction, Wears Quickly

BEST USES: Commuting, Road Biking

Poor bearing quality
The BB 7700 bottom bracket is worth the extra money if you can find it. It can be rebuilt too.
