What is so good about Token Ceramic Bottom Bracket

Traditional press-fit bottom brackets are notorious for creaking when the plastic cups shift inside the frame. Token’s Fusion Technology marries an alloy shell with a fiber-and-plastic composite. This allows the cups to fit incredibly snugly into the frame while providing a stable, vibration-dampening platform for the bearings.

Instead of pressing the bearings in independently and hoping they align, Token’s units feature an alloy sleeve where both sides screw directly into each other. This ensures perfect bearing alignment, removing stress on the bearings and preventing premature wear. It also effectively locks the left and right sides of your frame together to increase stiffness in the bottom bracket area.

To protect the bearings from grit, mud, and water, Token utilizes patented X-Seals. These seals create a tight barrier against environmental elements while producing minimal friction, allowing the cranks to spin freely.

Token offers these bottom brackets with either high-quality standard bearings or their proprietary TBT (Tiramic) bearings. TBT bearings utilize ceramic balls housed in extremely hard races, which significantly reduces rolling resistance and increases longevity.

Because they thread together, they can be installed and removed using standard bottom bracket tools (like those for Shimano) without needing expensive, specialized bearing presses. This makes them very accessible for home mechanics.

For riders with Trek bikes experiencing standard PF/BB90 issues, users on Facebook express a general consensus that Token BB90s are a highly recommended, low-maintenance upgrade.
