Token BB3724 31.7 - 37.2mm Zenith Ninja Trek BB90 or PF95 for Shimano Hollowtech II 24mm Axle In Trek Oversize Installations! The Ultimate Solution for Your High End Trek's Creaking BB (With/without SRAM GXP Conversion Spacers too) 


Trek had an issue with their interesting BB90/BB95 system, usually caused by the bearings seizing and then spinning around in the frame - it was so common, Token, came up with a solution. 

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. In our workshop we think this is the ULTIMATE SOLUTION - providing ULTIMATE SMOOTHNESS! 

So we have a three pronged attack to the PPP, or perennial press fit problem! 

1) 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. 

2) 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. 

3) 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.
