Control Tech Falcon Stem covers the whole road market. From serious racers to weekend warriors, and everyone in between: all can ride with perfect control Control Tech products address the three biggest issues first: low weight, for the fastest responses and superior performance; high stiffness, for the most efficient power transfer and accurate handling; and engineered-in compliance, to reduce rider fatigue and increase comfort. In fact, our superlight road components are so strong and rugged they work for cyclocross use too. The unique square tubular stem body adds an aerodynamic edge to your riding, as well as giving your bike a contemporary aesthetic. That aero appeal also continues with the 6061 aluminum stem caps: its low-profile design contributes to the wind-cheating performance. 6061 aluminum strikes a good balance between stiffness and comfort. 5° stem can be flipped for further aerodynamics or sit-up comfort. 10mm stem spacer gives a smooth transition from the stem to the headset top cover. In addition, comes in six sizes – 80, 90, 100, 110, 120 and 130mm – for more comfort and better handling whatever your size and style of riding. Also Weighs just 138g.
