Description

Dura Ace BB86 Bottom Bracket

Among bottom bracket standards in the bike industry is BB86. It offers frame designers a little more room for new designs in seat/down tubes and chainstays. Where a typical road bike has a 68 or 70mm bottom bracket shell width, a BB86 equipped bike has a shell that measures 86.5mm wide. A BB86 shell lacks internal threads and has a 41mm inside diameter.

This Shimano Dura Ace BB86 Bottom Bracket Assembly is made to press right into your bike. It will mate your Shimano HollowTech crankset to any frame equipped with a BB86 bottom bracket shell. Frames that use BB86 bottom brackets include bikes from Scott, Giant, and plenty of others. This bottom bracket comes with two steel cartridge bearings pressed into composite cups. The cups increase the outside diameter of the assembly to 41mm to match the i.d. of the frame's bottom bracket shell. There is a 1.75mm thick outer lip that provides a positive stop for the cups when you press them into place. Shimano includes their standard plastic o-ringed inner sleeve to protect against water damage should it find a way inside your frame. It uses black plastic dust shields that snap into the inner race of each bearing.

  • Press Fit bottom bracket pairs with your Shimano HollowTech cranksets
  • Composite cups and steel cartridge bearings add high quality to the design
  • Inner plastic o-rings and dust shields prevent premature wearing

I use this with Ultegra cranks on my Ridley Fenix SL. The best thing about a bottom bracket is never noticing you bottom bracket. Mission accomplished. It is smooth and reliable.

I have a Fuji nor Kam Tri bike It have a seal bearing Bottom Bearings or on each side I want to put my shimano Durga ace R9100 Crank set on it Which bottom bracket do I need

>Rating:

I currently have this BB in my bike with an Ultegra 11 speed crankset on a Merckx emx-7. I was thinking of getting a FSA Slk-k light 386evo crankset. Can you tell me if this would work or would I need another BB or some adapters? Thanks!

You will need a different bottom bracket (BB386EVO cranksets have a 30mm spindle, though the spindle length is the same).

There isn't much to say about a well functioning bottom bracket, and there shouldn't be. This works as designed with no complaints.

Smooth and maintenance free, isn't that what we want out of a BB? it is for my and after a summer of commuting, training, racing, I don't even have to think about it, it's always dependable.
