TOKEN NINJA FUSION PF BB8689.592 FOR SHIMAN BOTTOM BRACKET

DESCRIPTION

We don’t want to start a fight but we think it’s fair to claim that there are some problems with press-fit bottom brackets. They creak, don’t last all that long, and are installed and removed with tools that cavemen would recognize. TOKEN’s NINJA bottom bracket solves the creaking issues, improves bearing life, and adds stiffness to the bottom bracket.

We start with our Fusion technology; it is a combination of plastic and fiber that covers an alloy bottom bracket shell. The composite material allows it to be precisely machined and fit snugly in the frame so it doesn’t move in the frame and sound like grandma’s clicking and creaking arthritic knees. But plastic and fiber don’t do a good job of supporting bearings; poorly supported bearings can wear prematurely.

We house the bearings in an alloy shell and wrap them with plastic and fiber. 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 we 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.

FEATURES

• The NINJA bottom bracket is can be purchased individually or in a package that includes adapters to fit several different frame and crankset combinations.

• The NINJA bottom bracket doesn’t just solve the problem of noisy bottom brackets - it actually improves the life of the bottom bracket and makes your bike stiffer.
