Grrl's bike is mongrel combo of new Ultegra 11s shifters, old DA 11s FD, older style 11s RD and god-knows internal battery. Doing the double-press on the junction box changes modes but the thing doesn't do Syncro shift. Is there one component in that mix that's likely impacting this option? Would be nice to have it stop her cross-chaining by default.
