Brake post distances:
Front: 78mm c-c
Rear: 87mm c-c
I haven't found a definite yay/nay online but it looks like v brakes would fit.
According to Sheldon Brown, V brakes are not compatible with aero style brake levers (such as those on the Dawes tourer). Has anyone experience to the contrary?
You can measure the distance between posts and find out in advanced if Vs will work. Given it has an (early) disc mount, i'd be hopeful.
I believe the model that mount is for is shown on is top right
