" The Ninja cups still thread together, but Token has added a novel Pressure Relief Design shape to the frame interface that is designed to help the carbon-reinforced plastic cups slightly deform as necessary when installed in bottom bracket shells that aren’t quite perfectly round. In this way, Token claims the Ninja is therefore able to fit more tightly in those problematic frames without affecting the bearing bore (and, thus, bearing longevity). The design won’t be of any help on frames where the bottom bracket shell isn’t properly faced, but the idea is intriguing nonetheless for other cases where owners have had issues keeping their frames quiet.
