Token Premium Steel Bearing Bottom Bracket - Shimano

DETAILSWe 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.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.FusionFusion technology marries aluminum and nylon to give you a high-performance and squeak-free 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.X-SealTOKEN’s X-Seal technology keeps bearings protected from dirt and water, with very little friction for a free-spinning bearing.BEARING TYPE: Premium Bearing
