There is no 11 speed etap available and upgrading to 12 speed AXS etap is a bit more complicated and expensive. XDR wheelset or conversion, SRAM flat top chain, 12 speed cassette, new crankset or aftermarket rings, FD, RD, shifters, and of course batteries and charger. I am looking at this right now for a bike. There might be some short cuts but it isn't clear right now
