Chris King External Bottom Bracket Cup Tool

The Chris King Bottom Bracket is designed to offer season after season of smooth turning service. To ensure maximum performance we strongly recommend proper reaming and facing to be done to the bottom bracket shell by a qualified bicycle mechanic prior to component installation. *If you buy a frame and bb here, we'll do this during installation.*

For installation of the bottom bracket King offers the Chris King BB External Cup Tool. Their cup tool is anodized aluminum and features a 3/8" socket drive and recommend use with a high-quality torque wrench. The spline interface is precision made to match King bottom bracket cups ensuring a secure fit during installation while preventing finish damage.
