Identifying your Stages Power meter
Stages Power meters utilize a variety of battery cover designs which represent an evolution to the power meter's design and improvements to durability.
For Stages left-side power meters, use the image below to identify your power meter generation. For right-side and SB20 power meters, scroll down to the right-side section.
Stages Power Gen 1
Gen 1 power meters use a cover with 3 small tabs on the back. Your gen 1 power meter may have come with a black, red, or green o-ring. The green o-ring is our most recent o-ring and is ideal for your gen 1 meter. If your o-ring appears damaged or missing or your battery door does not seem to close properly, we highly recommend obtaining replacements in order to ensure the best performance from your power meter.
Please note that these Gen 1 o-rings and battery doors are not compatible with the gen 2 meters, which have a larger diameter battery opening.
Stages Power Gen 2 / Gen 3
The Gen 2/3 power meters include a revised battery door design from Gen 1, which fully contains the outside edge of the battery. These power meters come stock with either a blue or yellow o-ring. Both o-rings are functionally identical, with the color only changed to improve the visibility of the o-ring. If you have lost or need a replacement o-ring, a blue or yellow o-ring is required to prevent water intrusion in your power meter. We do not recommend in any instance substituting a Gen 1 o-ring or a generic o-ring of a similar size purchased elsewhere.
Stages SB20 and right-side power meters
Right-side road power meters and SB20 power meters use battery covers that attach with two screws. With the change in design from 11-speed to 12-speed Shimano cranks, the power meter design also changed and utilizes a slightly different design. Use the visual or the table below to determine which type of right-side battery cover your power meter uses.
