Hi. I have my hybrid Marin Muirwoods set up with drop bars. Currently I have the original linear pull brake levers and thumb shifters, pic below. I want to put brifters on it, either sti or ergopower levers. Is it possible to use them with v brakes? Also I know that the ergo's are more customizeable and easier to use with 3 chainrings...and 8 speeds...but can I use them with shimano derailluers? I hope so because I really want to clean the bars up and have more hand positions, including the drops.
