Your cart is empty. 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 fix for press fit, stiffer

I’m a professional bike mechanic (i.e. I get paid to work on other people’s bikes). I bought this bottom bracket for my personal 2019 Trek Domane Road Bike in April of 2024. Around March of 2025, less than a year, the left side bearing began to fail. A creaking noise developed. When I tore everything down I noticed a gritty feeling and sound with the bearing that side. Needless to say if you want a quality replacement for the press fit BB90 in your Trek, do yourself a favor and go with something else.

Finally a solution to the dreaded (and utterly ridiculous) bb90! Love this self-threaded bb. The only advice I would give to potential buyers is to make sure the special tool is FULLY seated (it's a very shallow recess) when torquing because you don't want to strip the grooves.
