I have a giant tcr originally from around 2012 which I acquired a few years back.
does anyone know what these two little holes in the non driveside chainstay are?
they seem to have a thread. are they for mounting something? am I missing my kickstand? Is this where the engine goes?

It’s for mounting the old Di2 battery
Yes old di2 batteries were external
Cadence sensor for cranks.
TCR used to have the giant specific sensor mounted here as in the image.
Di2 battery was mounted on inside of front triangle of original ultegra and then it went into seatpost.
JATO pod attachment point.
