The Stages Replacement Battery Door is a direct replacement for the original one that came on your Stages power meter. We stock replacement doors for both the left and right crank arms.
Notes on left battery doors:
These are intended for use with the Stages Generation 2 and 3 power meters only. Please note the Stages Generation 1 uses a slightly different size battery door and O-ring, which we don’t stock. If you are not sure which version you have, please refer to the comparison image on this page.
The left battery doors also come with a new factory O-ring. We recommend replacing the O-ring along with your new battery door.
