So I’ve currently got the previous gen Red AXS 12 speed group on my road bike and I’m considering switching bikes to something with gravel capability. I’m thinking I can just buy a Red XPLR rear mech and cassette and run my current red shifters and crank (I’d need a 1X chainring). This should work right since it’s all 12 speed AXS stuff? Wheels are XDR which should take the 13 speed cassette.
Current shifters and crank are ok, even the chain if it enough long.
but you need udh frame
It should work. Make sure that your new frame comes with UDH. Check the chain length on SRAM site, you likely need a new one.
