@klunkrider Cues does look like it will help, but not yet, as i understand it, it runs an 11 speed chain, which suggests 11 speed spacing regarless of 9, 10 or 11 speed being used, there are many price point options on the chainsets along with many 1x and 2x options, currently the gear shifters are specific to flat/riser bars and i am lead to believe it has it's own cable pull ratio, although i have heard that a deore m5100 11speed shifter works with the 11 speed option, currently there are no drop bar shifters that are compatible with it but apparently that is the plan. the whole idea is to make the cable ratio the same reagrdless of how many gears you have so all the rear mechs for example should work on 9,10 or 11 speed set ups and the chains and cassettes should also be compatible.
i looked at using some on a build in the last few days, i'm trying to work out if a sora/tiagra or 105 lever may work, as i'm in the process of building a road/touring style bike, will ask Madison tomorrow but i have been told they may not know themselves!
i wish they'd keep as simple as this, all 8 speed works together, regardless of road/mtb/hybrid, same with 9, 10, 11 and 12, imagine how nice it would be to decide how many gears you want then just pick the mix of mtb/road parts that work for you and know because you have bought all 10 speed it'll work, so a tiagra shifter with an xt long cage mech to get a wide ratio etc, seems pretty straight forward to me.
