Depends if you want a clutch mech or not…..
If you do, then SRAM CX1 / Force / Rival etc is about the only off the shelf option with flappy brake levers (I think).
You can also get the Gevenalle levers to suit a Shimano 10spd mtb clutch mech. They come with two brake cable positions so will work all options for cable brakes (cantis, road discs, vees or mtb discs). My mrs runs this 38:11-36 and it is OK but a little clunky.
Cheapest option is maybe use your existing Sora STI levers (are they 10 spd?) with a 9 speed Shimano mtb mech which will then work a 10 speed 11-34 or 11-36 mtb cassette (it is 1mm different overall width to a 10spd road cassette but works ok).
Other options? An 11 spd Shimano mtb / road version of the above mash up (non-clutch mech). Travel agent roller things? Di2!
