I posted some info about sensah shifters in this post:
https://www.bikeforums.net/bicycle-m...-shifters.html
and my conclusion was that the brake cable pull of Sensah shifters is longer than traditional Shimano (or SRAM or Campy) shifters and is similar to new 105/Ultegra/Durace. This means they "might" be OK to use with V-brakes as these also need a longer cable pull than road, cantilevers or mini-v brakes. Anyone upgrading an old v-bake equipped hybrid or mtb bike to drop bars might want to give them a try before concluding the brakes will need upgrading.
