The der. pull ratio is compatible with 11 speed derailleurs (and, hence, shifters). However, 11 speed shifters would require an 11 speed cassette in order to shift properly. So front shifting would work fine, but for the rear to work, you either need 11 speed cassette and 11 speed shifters, or compatible 10 speed shifters of other make. So far, the only ones I know are the 4700 shifters.
