Why don't road bikes use v-brakes? In my experience, linear pull brakes (v-brakes) have more stopping power than other types of cantilever brakes (let the flames start ;). Modern road bikes always come fitted with dual pivot brakes. There isn't a massive difference in weight (Similarly priced XTR v-brakes @ 400g (F&amp;R) VS Dura-Ace dual pivots @ 314g (F&amp;R)) so I'm wondering if there is another reason why road bikes don't use linear pull brakes?


Is it to do with 'feel'? 
Are my road
brakes rubbish, and most sets are
actually as powerful as v-brakes?
Obviously, current road levers
wouldn't work (well) with v-brakes..
Is it a pure legacy reason that
v-brakes aren't used?
It may be tradition, and it may be aerodynamics.   Note that some roadsters do... Touring bikes have gradually been switching from the traditional cantilevers to V-Brakes.  It's for tire clearance mostly.
"Good" caliper roadster brakes are very powerful; A set of high-end Shimano jobs (105 or above) will lock your wheel and they are routinely used by pro road racers.
They have a minimal aero profile and contribute little drag.  They also look good on a sleek roadster.
Also, you don't have to weld or incorporate lugs onto your snazzy carbon-fiber fork legs and seat-stays, which results in a "cleaner" appearance and less weight as well; high-end roadsters are all about weight, as you likely know.
