Product Details:Rock-solid stem and faceplate made from 3D forged 6061 aluminium, a combination proven to increase strength and reduce weight,The ‘forged’ method of manufacturing is significantly stronger than ‘cast’ but requires less material, resulting in a stiffer and lighter stem,Because correct stem length is vital for a comfortable bike position and good handling, the CLS stem comes in various sizes,Easily flips to give a 5° rise or drop depending on your aerodynamic ambitions,SCM-435 steel bolts adds further strength while providing a secure fit,Fits 28.6mm steerers and 31.8mm bar clamps,Weighs 110g (100mm),.Key Features:Made for road racing, sportive riding and cyclocross,Material: 6061 forged aluminium,Bolts: SCM-435,Rise: +/- 5º,Clamp Diameter: 31.8mm,Steerer Clamp: 28.6mm,Stack Height: 40mm,Weight: 110g (100mm option Reliability: Controltech USA knows the combination of sound engineering and high-quality materials practically guarantees the lifelong performance you expect. They never compromise our designs at the expense of low-quality materials. They use only premium grade raw material of aerospace quality.Ingenuity: Controltech is, and always has been, a global leader in component design. The state-of-the-art manufacturing technology would be nothing without the cutting-edge innovation of our Global Research & Development Team.Quality: A precise, unflinching view of manufacturing tolerances and meticulous craftsmanship are the hallmarks of Controltech components. Craftsman-level alloy welding and carbon layup are hallmarks of our designs. Plus of course, the use only premium-grade raw materials in the first place.Value: Though the greatest innovation takes place on the cutting edge of material science, manufacturing processes and product design, there’s such a thing as ’trickle down.’ Today’s no-expense-spared prototype is tomorrow’s easily-obtained standard. ControlTech work hard to create a range that covers every riding style, every rider and every budget – without ever sacrificing class-leading performance..
