Electronic shifting for 1X systems
If you are considering going to electronic shifting on the rear then you might want to consider NXS Wireless. https://www.nxswireless.com/
I just installed it on our 1X10 system on our Calfee Etandem. The nice thing about this system is that it can be setup for any rear gear combination. 6-12 speed. It is also reasonable. Under $300 for the rear shifting.
it does require the use of an android phone for the initial set up.
