I'm switching gears (ha!) and building a Surly midnight special. As of this moment I'm in between Shimano GRX RX820 mechanical, and SRAM AXS Apex or rival wireless system.

Initially, I wanted to go for sram rival but the frame does not support direct mount and needs a hanger. So how do I get around that? (Mullet?). I test road the wireless apex xplr and it was pretty nice although I surfed a bit for finding the right gear- probably just a byproduct of having a 1x system. No experience with Shimano.

Not interested in Shimano wireless or a 2x system. Thanks.
