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 recognise. 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 fibre that cover 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 fibre 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 it 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 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.


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. 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.

Great BB!

Best option on the market to replace the press fit BB.

Unfortunately I ordered the wrong part... sigh. The RMA process was pretty good.

So far so good

The part installed relatively easily, but I would prefer not having it recessed and having to use a highly specialized tool (that has no other purpose). Maybe consider having it fit against the outer shell AND allow the use of a 16 tooth T47 tool? See photo below (Wheels Manufacturing T47).

Wasn’t happy about the extra tool. If they had bundled it, I wouldn’t have noticed.

Goodbye to the creaks and other annoying noises. It’s a winner for sure. Worth every penny.

Saved my bike

This bearing saved my bike. Had an issue with loose BB90 bearings on my Trek Émonda SL6 due to frame expansion. Token recommended to buy the oversized version and the replacement was very simple and easy with the tool. My bike is finally usable again and I don’t think I have to worry about loose bearings mid ride anymore.
