Save BIG with our bottom bracket retro-fit Kit!  Comes with custom made housing, bearing insert, and replacement tool.  Your current Factory bottom brackets are expensive and uses a press fit permanent design that does not allow you to replace the bearings inside yourself, nor will it fit any production bearings available in the US.  So we created a new housing with a screw in bearing design that allows you to easily and affordably make this repair yourself on the fly!   Once you have our housing you will be able to replace the much more affordable and Locally sourced bearing on your own!  Simply unscrew the bearing housing with our removal tool and replace with a new one!  Super easy and at about a 75% cost savings of replacing with a factory set up each time!  Great set to allways have on hand!     (reminder: Bearings, and tool are available seperately as well.  Our bearing inserts will not fit the factory housing, only ECS version)
