Castelli has introduced its latest jersey and bibshort called the Aero 6 and Free Aero Race 4, which the Italian brand is calling its “fastest and most comfortable” jersey and bibshort to date.
The Aero 6 is the latest iteration in a long series of race-tested jerseys that dates all the way back to 2009, when Castelli first partnered with teams like Cervelo.
According to Castelli, the Aero 6 draws upon everything they learned over the years, seizing every marginal gain possibly to make the jersey the slipperiest ever, which the company claims results in a 15 watt drag reduction at 30mph (50kph) and 3 watts at 25mph (40kph).
Castelli attributes this in large part to analyzing the placement of every seam via extensive Computational Fluid Dynamics and wind tunnel testing before deciding on their final design.
In addition to improved aerodynamics, as previously mentioned, the Aero 6 focuses on comfort as well, taking into consider the shape and placement of each panel and seam in order to achieve optimal body positioning. Moreover, improvements in material has also made the new jersey more effective at managing moisture and providing better ventilation, including extended, raw-edge sleeves that now sit below the elbow and a minimalist collar design.
The Free Aero Race 4 bibshorts feature Castelli’s latest Progetto X2 Air Seamless chamois, which gains a softer, more flexible pad, along with a new seamless top layer.
Additionally, the Free Aero Race 4 also possesses a new leg opening design that employs stretchier, laser-cut material with vertical silicone stripes on the inside for improved fit and comfort.
Other features that punctuate the Free Aero Race 4 bibshorts are narrower, more breathable straps made from lightweight, mesh fabric, a slimmer back panel and dimpled fabric for added aerodynamics, as well as a small pocket for stowing a race radio – a nod to meeting the needs of the modern-day pro rider.
Pricing for the European market puts the Aero 6 jersey and Free Aero Race 4 bibshorts at £110 and £150 respectively.
