Stems are a component easily overlooked on a bicycle. Often times, they only get swapped to change length for fit. Why else would you change one? Wren seems to think you should because they have designed a stem that is 3D forged of light AL7050 alloy. Wren forges the stems as opposed to CNC machining as it allows for better grain structure and strengthens the material. What's this mean to you? How about a stem that is significantly lighter and stronger than the one that came on your bike and than most aftermarket stems. Too good to be true? Wren sweetens the deal by making it one of the best values on the market!
