>>1212545Gevenalle makes these but they are expensive as fuck and it's really just a down tube shifter attached to a single speed hydro brake lever so doesn't work like proper STI ones do..
With old Campagnolo front indexing you could use the same levers with double and triple cranksets, but no idea if the current H11 hydro levers still work the same. That's a grossly overpriced option as well.
Probably the best idea to just go with either a Shimano 2x11 or SRAM 1x11 hydro setup and run the front shifter with a bar end and the rear shifter with the STI paddles.
