To maintain your indexing, you'll need a shifter that pulls 2.35mm of cable per gear change. That should be basically any Shimano 2x10 road shifters except for the current-gen Tiagra 4700. There are some Shimano-compatible shifters out there that should also work, like the Microshift 2x10 Thumb Tap shifters.
