The Viking Stem is one of the first fully machined stems available at this price point. Continuous 3D CNC design iterations have created a final product that saves both machine time and materials. The Viking takes many proven features from The Rockville Stem and delivers them at a mid-level price point. It's available in both a 31.8mm and 35mm handlebar clamp diameter in a 40mm length.   We are on a mission to make phenomenal products that support the sport of mountain biking. For every Viking Stem sold, we will donate $1 to LB-Cycle in Lac Beauport, Quebec, Canada. We exist to support the trails we love, the people that take care of them and to make your riding experience exceptional.
