Every Profile Design product is perfectly optimized to minimize aerodynamic drag. So, it's no surprise that Profile's Aeria Stem has hidden bolts and a low profile faceplate to smooth oncoming air. The sculpted shape is constructed from strong, lightweight forged aluminum, and the 17-degree drop ensures an aerodynamic fit on your time trial or triathlon bike.
