Archer components have shifters that can be integrated in the right Hylex lever and it's all modular, so I'm thinking that as soon as it becomes available on this side of the pond I'll give it a go.
They also have an option that's similar to the the SRAM blip box for AXS.
Like that very much. Not sure about the gear shift box, shame they don't do little blip buttons, summat a bit more discreet.
