Travel Agents worked for me with Ultegra levers. I got them mail order from Harris Cyclery. Or alternatively Dia-compe make drop
handlebar brake levers that have the correct mechanical advantage to work with v-brakes.

It's very bad.  My Voodoo Wazoo cyclocross bike came stock that way and I
have tolerated it for over a year.  It's in the shop now getting old-style
LX cantis.  Yes there was a roller-thing in here to increase the brake force
but it just isn't enough unless you constantly adjust and replace the pads.
I've seen a couple of other cyclists around my city with the same bike and
they had switched to cantis.  One fellow told me that he now measures the
pad wear in months instead of days.  Can't wait to get mine back from the
shop to test this theory.

http://www.phred.org/~alex/bikes has an article that I've written on this
(complete with pictures of three different devices that allow V-brakes to
work with drop-bar levers).

My preference is to use Diacompe 287-V brake levers.

  Why do you want to use V-brakes specifially?  The reason that the V-brakes
are so popular with the MTB set is the lower lever pressure they give.  With
the 105 levers the same low pressure is available with the simpler, cheaper and
LIGHTER canti brakes.  I am running 105 aero levers on my touring commuter with
LX cantis and Koolstop pads and I get lovely one finger casual stops in dry and
wet and I can easily lock up the wheels with two fingers from the hoods.  This
is a GREAT combo and I recomend it highly.

Hi Bruce,

I bought a touring bike with V-brakes and a MTB steering bar and bar-ends
but I don't like it so I want to chance to a dropbar with race brake-levers.
Because I already have the v-brakes and like their braking-performance I try
to combine and have the best of both. That's the reason.

Bye, Ronald.

I just switched from V-brakes with 105 levers on a drop bar using the QBP
Travel Agents to cantis.  I haven't had a chance to use the cantis yet
(haven't actually installed them) but IMHO they will be far superior to
the V-brakes.  Even with the Travel Agents (which are supposed to decrease
the mechanical advantage that non-V levers have) and the pads set up
anywhere from 1-5mm from the rim, the brakes were squishy and offered very
little modulation.

YMMV of course but I would consider getting a drop bar and using
cantilevers instead.

Good luck,

Eric

I can appreciate that you want to use what you already have.  V-brakes have a
great reputation for good stopping power but you have to consider that it is not
just one part but rather the whole system of levers and calipers that work
together to give the modulation feel to the brakes.  You have to make your own
choices about what you like but as a suggestion why not find someone with an MTB
with LX or XT cantis and offer to trade  your V's for his cantis and a little
extra cash from him/her.  The extra goes into the 105 lever fund and all are
happy.  The references I read in this thread to the extra parts needed to adapt
the V's to the levers sounds clunky and breakable to me.  Simpler is almost
always better and in this case I think you would be pleased with how they feel.
  By the way my Miyata tourer/commuter is now equiped with STX-RC shifter pods
on the drop bars near the stem.  I got them to fit by lightly machining out the
mounting brackets to fit the drop bars.  A metal lathe helps but a careful job
with a half round file of about the same curve as the bars will do almost as
nice a job.  It's not as tidy as Ergos or STI but much less expensive and works
very nice. (MTB stuff on the back of course)
   Anyway you go it is nice to give life back to a good old frame.

I did something similar when putting a Nexus hub on a road bike, but I
mounted the shifter pod at the bar ends.  Mounting near the top doesn't seem
like it would have very good ergonomics.
http://www.phred.org/~alex/bikes/trek400 has a picture of the shifter
mounted this way.

There isn't any reason to use MTB stuff in the back... Shimano road shifters
have no problem with Shimano MTB derailleurs and visa-versa.  Most of my
bikes are using hybrids of these groups for their drivetrain.

please confirm the function when you're using brake lever for road bike with
V-brake, leverage for road bike might not be enough for V-brake.
be careful....
