Chris King Bottom Bracket
The Chris King bottom bracket is specifically designed for Shimano-compatible external type crank/bottom bracket systems and delivers every benefit you've come to expect from King and in the wide array of colours only King can do. An available grease injection tool allows the bearings to be purged of existing grease and debris and new grease run through. What better way to maximize the life of your bearings than to do routine maintenance? Especially when it's this easy.
