Hi there i run a v-brake rear mounted and shimano xtr hydrolic disc brake sutup on my mountain bike but as my confidence and skill(i hope) has increased if found that the braking of the v brake on the rear isnt enough the problem is i have no mounting points for a rear caliper for a disc convertion on my frame,i have disc compatable wheels that isnt an issue but i dont want to buy a disc setup if i cant find a way to fit it?
