yeah totally, but there is a trick
those shifter will work fine with your set up, as long as you have the correct number of index positions (I.e. 8 spd shifter for an 8 spd der). The trick for the brakes is a little hidden. If you squeeze the lever without any cable in the hanger you will see a red tab with the letters c and v on it, attached by a small phillips screw. Switch the tab so that the c (for caliper) is located next to the hanger. The v is for v-brakes and is the wrong actuation, resulting in sloppy performance. If you have the paper work for the shifters it has a good diagram on how to do it. Hope this helps. post some pics when your done.
