Description
The Token Ninja Bottom Bracket BB86/89.5/92 for Shimano 24mm is a great performance upgrade to your bike, offering incredible stiffness, increased bearing longevity and the elimination of any creaking that can be an annoyance of many bottom brackets. Fusion technology is key to the construction. This plastic and fibre covering is precisely machined to ensure a snug fit in the frame and no movement. The bearings themselves are housed in an alloy shell that's wrapped with plastic and fibre. This solid platform results in improved longevity. The alloy shell has also been extended to lock the left and right sides together, significantly improving stiffness for exceptional power transfer.
