SRAM will be 12s, GRX 11s? SRAM seems to be the pioneer for 1x stuff, and the wireless would be super nice. 1x for gravel/road I'd want as many gears as I could afford.
Personally I'd go with 12s Shimano if I could get it (just Ultegra and dura ace for now?) or Campy Eckar.
I ride 11s 105 so probably should ignore me
That $1,000 saved would go a long long way towards nice shoes/tires/bags!
