2019 Castelli Womens Free Aero Race 4 W Bibshort : Team : Black/Aruba Information

Season : Spring Summer 19

Brand : Castelli

Code : CS19077BLKArubaBLU

12 years in the making with millions of kilometres of pro peloton development, the Free Aero Race 4 is Castelli's fastest, most comfortable racing bibshort to date.

The new Free Aero Race 4 is the latest evolution of Castelli’s original Aero Race bibshort, which gave Castelli riders an aerodynamic edge in the peloton when it launched in 2007. The pros ride over 30,000km a year, so they're the ideal testers for Castelli and just as preoccupied with comfort and performance as enthusiast riders. 

More than a decade on from the original innovation of the Aero Race bibshort, Castelli’s close relationship with Team Sky athletes has once again yielded a performance advantage on the WorldTour scene – minimalism meets speed and comfort.

The result is the Free Aero Race 4, a pro-level short to be used by Team Sky in 2019 that's now available to all riders.

When it came to improving on Castelli's best-selling bibshort of all time, the Italian brand's R&D team worked closely with Team Sky riders, visiting the squad in Belgium, Nice, Manchester and all around Italy to get training and racing feedback.

The consensus was that the existing Free Aero Race was already a really, really good pair of shorts – but there were still gains to be made. As 'good enough' isn't part of the Castelli lexicon, the design team listened to every bit of feedback from Team Sky.

Armed with this, along with Castelli's own constant testing and drive to improve on the short, the 2019 Free Aero Race 4 bibshort features some dramatic, performance-enhancing changes.

The Free Aero Race 4 has been completely re-engineered to improve the short's performance without losing the spirit and clean lines that have made this peloton stalwart so popular.

New Vortex dimpled fabric discourages air attachment so that it flows cleanly off the back of your legs while riding. This new design also allows for a better print quality too. 

To ensure compression is only applied where needed, Castelli has overhauled the short's leg grippers. The new Giro4 design features a lie-flat raw-cut edge with vertical silicone stripes. This better distributes grip over a larger area to keep the hem in place without restricting stretch and leg movement.

The inner legs feature Forza fabric for a smooth, snug, unrestrictive fit thanks to 38% Lycra content. Castelli has also completely redesigned the short's panelling with the new Doppio V construction improving fit and support while also making the short look even cleaner than previous versions. 

The Castelli team has re-engineered the Free Aero Race 4 bib straps with new lighter, more breathable material. The result is that they have better moisture transfer to keep you cooler and drier while also lying flatter for even more of a forget-it's-there feel. They're also more durable than ever before and look fantastic with a new pinstripe design. A new loop for a race radio microphone was added at the request of team riders.

The Free Aero Race 4 Bibshort incorporates Castelli's brand new Progetto X2 Air Seamless seat pad, which features a two-piece design.

Thanks to Castelli's advanced use of fabric technologies, the supportive foam core is slightly narrower and smaller than before. This is because the design's flexibility and elasticity mean it sits exactly where it needs to be – meaning it doesn't have to be wider than your saddle.

The upper layer is dimpled to reduce full skin contact, encouraging air to drive moisture away from the body. It's also more elastic so it doesn't fold while the finish is the softest ever on a pair of Castelli shorts for luxurious comfort next to the skin no matter the length of your ride.

To better cater for the needs of female cyclists, Castelli has created two versions of its most advanced racing short. Developed alongside the men’s versions of the short, the Castelli Free Aero Race 4 W is a pro-level women’s-specific short available in two styles – with and without bib straps.

The Free Aero Race 4 W bibshort design is available in standard, Team Sky or Team options, the latter featuring an extra flash of colour on the legs. For both of these options, Castelli has implemented its redesigned straps – tried and tested by Team Sky and Castelli’s team of female testers.

For the short versions, Castelli has opted for a comfortable high-rise waistband that holds the shorts in place without restriction and gives the same coverage as the bibs to ensure there are no gaps between jersey and shorts. There's also the added benefit of making nature breaks that much more convenient.
