isn't the reason road bikes don't have disk brakes because disk brakes are heavier? do you ever find yourself
needing disk brakes on a road bike?
(or wishing you did have them?)
It's a rarity for me to want disk brakes on my road bike, but it would save on the wear and tear on rims. I guess the braking maybe a bit better in wet weather too (though probably not that much).
I think that as a general rule disk brakes are heavier, but you can get some incredibly lightweight systems these days, certainly ones to rival V-brakes, so I don't see why they shouldn't rival dual pivots too. Of course this is taking into account the weight savings that can be gained by using disk-specific rims too.
edited to add - I don't think they are
needed on a roadbike, but sometimes it would be nice!
