I'm working on my A7 project frame...
(Purists will cringe, but prepping it for a rigid hardtail conversion)
I have a small tang that sticks out just above the mounting hole for the rear brake lever.
Is this for return spring? or brake light switch? or none of the above?
I've never had an A7 together, so I'm not sure if it can be eliminated.
Thanks in advance!
