Dura ace Bottom Bracket – BB86

Shimano Press Fit Bottom Bracket with Inner Cover 86.5mm

TheShimano Press Fit Bottom Bracket with Inner Cover 86.5mm is the perfect bottom bracket assembly for Shimano HollowTech II road cranks.

This is the complete press-fit bottom bracket kit so includes both the right and left hand cups, inner O-rings and inner cover.The cups are constructed in a polymer material that has been reinforced with fibre to protect your frame from damage, and your ears from noise.

As with all Shimano products, the design here is well thought through.Sealing the cups means they are protected from water and dirt, making this bottom bracket almost maintenance free.

Press fit installation is both easy and phenomenally stiff to give you the best of everything.
