From Split Second to Aero Pro In the past, performance cycling jerseys were all about moisture management with little to no attention given to aerodynamics – that was a consideration for time trialling only. Baggy cycling jerseys were the norm until the very first Castelli aero focused jersey appeared- named the Split Second. However, with every new version of the jersey, the aerodynamic advantages have proved to be worth far more than just split seconds. Using CFD (Computational Flow Dynamics) to analyse wake-flow, the Women’s Aero Pro Jersey will fit you even better when you’re in an aggressive riding position while seam placement has been optimised to minimise drag. At speeds of between 30 and 55 km/h, the aerodynamic efficiency is optimised giving more speed without an increase of power output compared to a standard jersey – you could almost call it free speed. Cool and Fuelled Of course, riding fast, whether in training or racing, is going to generate heat. That, in turn, leads to sweat. However, the Women’s Aero Pro isn’t just efficient through the air it’s also efficient in dealing with moisture too. Quick wicking and with a 3D mesh back you’ll be cooler and drier as you push hard on the pedals. To keep you fully fuelled for your ride the pockets are easily accessible when stuffed with gels and thanks to the drop tail design the jersey remains sleek even when they’re loaded up. The Women’s Aero Pro Jersey is Castelli’s most aerodynamically advanced design to date and yet it’s also their best fitting too – Just ask their WorldTour professional riders. A remarkably comfortable high-performance cycling jersey whether it’s your longest days in the saddle or a short and intense criterium race.
