Question: I would like to try the drop handlebar on my touring bicycle that has V-Brakes, and Shimano 9x3 speeds. Are there drop handlebar levers (integrated shifters would be great), that have correct pull ratio for V-brakes? 

If there are brake levers but no shifters, where would be a good place to put my existing (deore shifters) on the drop handlebar?

Answer: 
Sounds like you want to use your current V-Brakes, but if getting new brakes, TRP makes mini V-Brakes that are STI lever compatible, sometimes called a brifter (brakes and shifting in one lever). Most V-Brakes have a different pull ratio which is not compatible with brifters.

The [TRP CX9](http://rads.stackoverflow.com/amzn/click/B004C966DK) is for Shimano STI levers

The [TRP CX8.4](http://rads.stackoverflow.com/amzn/click/B009IJAPG8) is for SRAM and Campagnolo levers
I have a Surly Long Haul Trucker which came stock with dropbars and Tektro 992 “Oryx” brakes cantilever brakes and levers. I have now switched out those cantilever brakes out for Avid Single Digit 7 v-brakes and to specifically answer your question fitted Cane Creek Drop V brake levers. These are not integrated shifter levers but, so I still have my bar-end shifters.

For me this update has significantly improved the braking on the bike.
