The Token Ninja press-fit, double thread bottom bracket includes premium high carbon steel ball bearings and features multiple technologies which provide a smooth, stiff, quiet and low maintenance performance. Note: CAMPY bottom brackets do not include bearings. Thread together double thread provides a faster installation plus less axial force. The two sides of the bottom bracket screw together reducing the chances of bearing misalignment which can cause premature wear. Premium Bearings are high carbon steel bearings that are made to higher standard so they run smoother and last longer for those who ride often in all conditions. Fusion technology marries aluminum and nylon to give you a squeak-free bottom bracket. Token's X-Seal technology keeps bearing protected from dirt and water, with very little friction for a free-spinning bearing.
