save your money and stick with your v - brakes if you not having a problem with them. i've got v's on my one bike and disks on my other and you aren't going to notice the difference unless you riding in the rain or snow. (if you can lock-out your v's then they don't have a problem with stopping power.) if you doing serious down-hills or long races such as the epic you going to be looking at a new bike that comes with hydrolic disks anyway. disks aren't always the answer. lots of people finished the 2nd day of the epic complaining that their disk pads had worn downand they had no brakes, but they actually were clogged with the that lekker klein karoo dust, while those few with v-brakes had no ploblems.
