When I got my bike from BikesDirect.com (Fuji road bike SL 3.2), it came with these two little pieces (about 1/4" x 3/16"). I have no idea what they are for, but the bike seems to do fine without them. They have a small adhesive patch on one edge. The pieces are made of steel. Does anyone know what they are for, and if I need to keep them? Thanks! -- Craig
