Your current Factory bottom brackets are expensive and use 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 always have on hand!   Repair tool available seperately or as part of kit.  Full bike retro-fit kit is avaliable at a deep discount as well!
