The Goal: Ultimate Speed.
The goal was clear: Forget limitations, ignore conventional wisdom, and create a race-winning aero road bike without compromises. To achieve what was previously unachievable.
Superior aerodynamics is a critical part of the equation, but our team of engineers, aerodynamics experts and pro racers wanted more. So we began the process of building an aero road machine that also delivers measurable gains in control and efficiency. It would have disc brakes integrated into the overall design. It would be light and stiff, and would offer previously unattainable aerodynamic performance. It's easy to improve aerodynamic performance by sacrificing stiffness or weight. But we committed to key design elements including a larger headtube, downtube and bottom bracket area that we feel are critical to the bike's efficiency and handling. These decisions help give the Propel Disc an even better stiffness-to-weight ratio and put it well ahead of competitors.
It took three years, radical experimentation with tube shapes, and hundreds of iterations in CFD and wind-tunnel testing, but the final results speak for themselves. The new Propel Disc range delivers ultimate speed with three key benefits: integrated aerodynamics, total control and unrivaled efficiency.
