There aren’t many times a replacement part actually improves your bike but put one on your bike and you’ll wonder why you didn’t install a NINJA sooner. The bearings are housed in an alloy shell and wrapped with plastic and fibre. This fusion of the three materials provides the bearings a solid platform to sit on and extends their lives. A lot of people would be satisfied with this, but they went even further by extending the alloy shell so the right and left sides lock together. This locks the frame, cranks and bottom bracket together and provides unparalleled stiffness.
Precision engineered Dura-Ace 7710 Bottom bracket for Track Octalink splined system.
These custom, Swiss made bearings are double sealed, fully serviceable and removable which give a much greater life span than stock units. The bearings are made (as all Hope bearings are) by INA and have been designed to run directly on the crankset axle without using shims or spacers -again increasing life and reliability. Hope use a non-contact, free running labyrinth seal to protect the bearing externally, and the machined aluminium centre tube is sealed internally with o-rings. Standard 6 colours are available on cups - red, blue, silver, black, gold and gunmetal, with the centre tubes being black on the stainless and gunsmoke on the ceramic. Please Note: The 68/73mm width option is the universal type for both MTB and Road bikes, it is not the Hope Road Specific Series model. For the Road Specific model, choose the "Stainless Steel Road" option. Tech Tip: the 68/73mm width option is the most commonly used size for threaded road and mountain bike bottom bracket shells. The wider 83mm width is mainly seen on "downhill" (ie. long travel) mountain bikes. Please confirm the width of your bike frame's bottom bracket shell before ordering.

The smooth running fully sealed also ensure your drivetrain will keep running smoothly and in all riding conditions. Manufacturer's Part Number: BBPF4130SS
