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.

Improperly Packaged, Dirty, Used

My bottom bracket was poorly packaged and not properly secured, so when it arrived it was no longer in its box. It was also dirty and greasy, and looked like it was previously installed. Not happy at all.

Great replacement

Easy replacement for BB90. Threaded together really nicely, feels way better than the bb90 that came with my bike. As some people mentioned, it takes the larger 1/2” ratchet, so make sure you have a 1/4” to 1/2” adaptor. Also, I went nice and easy on the threading to not cross thread. They are machined well, but are fine threads. Looking forward to worry free riding.

Stunning addition to my tired rusty bottom bracket

My bottom bracket was leaking a thick rusty gunge... how awful!
The Trek BB is absolute crap and just spins in the frame allowing the non drive side to rust up and just fall apart.
The Token BB is amazing.. easy install (make sure you buy the install tool) and then you have a new bike... well feels like it anyway :-)

Awesome option to traditional bb90 bearings

My 2016 Trek Domane 6.2 developed the infamous bottom bracket creak. I chose to use the Ninja bb 90 replacement, BB3724, and couldn't be happier so far. Install was straight forward and the BB feels very smooth. Kudos to Token in that on my initial order the tool was ordered with the bottom bracket and it had obviously had been pilfered from the package while enroute. The company was immediately notified by email and quickly got another tool shipped. Thanks for prompt respones!
