Control Tech CLS A/Head 6061 Road Stem 31.8mm All Sizes 

It’s easy to make a simple product look simple – but it takes genius to make a complex one elegant. That’s where Controltech excels. Components such as handlebars, seatposts and even wheels may look simple, but if you want high performance, you inevitably introduce a great deal of complexity under the skin and behind the scenes.

At Controltech, we break that down to four key elements. First, there’s the ideas stage, but even our Research & Development is inextricably linked with a hard understanding of materials and manufacturing. Our innovation and engineering overlaps real-world riding with pure science and good engineering – it’s the only way to work out not just what’s possible, but what’s desirable.

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.

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
