I'm thinking of getting the Wolftooth roadlink and want to try and keep Shimano cassette and my short cage di2 RD. I have DT Swiss rear hub that didn't fit 11spd MTB cassette for some reason. I think the MTB cassette in 11spd is skinnier or wider?
There is an 11-34 11 speed Mtb cassette that will work with 10spd hubs, and the new medium cage ultegra rear mech can work with it too.
Double chainrings are only supported with GS (medium cage) rear derailleurs. (?)
