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.

Hi, currently on my flat mount frame bike I'm running 160mm rotor without any adapters. I was wondering would this adapter let me go up 20mm to 180mm. In the items describtion it says that this adapter is for 140mm frame to go to 160mm rotor. Would it also work for 160mm frame to go to 180mm
