I had a user ask what does this switch do so I am answering here.
Some users have power meters, specifically power meter pedals that may only submit 1/2 the power from each side. We don’t support the ability to connect to two pedals at the same time so doubling the power will solve some users issues. If you have Assioma pedals you can use their app to double the power but you may prefer to leave them as single sided for Garmin recording outside and then just double it our app. If you don’t have a power meter pedals this switch will not do anything.
