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. Next, we look at aerodynamics, using a mix of Computational Fluid Dynamics (CFD) and real-world performance testing. It’s a vital area for road and especially triathlon products, and our longstanding expertise in carbon fiber and high-precision alloy milling mean Controltech’s use of shaping is second to none.
