I have a quick question, I am putting together my sons bike for christmas. I purchased the fork and frame months ago, but I just realized on the brake bosses.. mounts whatever they are callled for v-brakes. They screw into the fork since then you can remove them if you want to use disc brakes. I am using v-brakes since had a spare set that I never used. THere is this metal post that screws into the fork, also from looking at the manual there is a piece that goes on the bottom of the post that the v-brake spring connects to that is missing. Anyone know the name of this piece, I know it is to late to get it for christmas which really sucks, but need to get that piece can my LBS order it for me and anyone know the name of that piece.
