Designed for female riders, the 2019 Castelli Team Sky Free Aero Race 4 W Bibshort represents a significant evolution from last year's model, Castelli's best-selling short ever.
The new design draws on feedback from Team Sky riders and Castelli's 10 years of aero bibshort evolution to deliver some dramatic, performance-enhancing changes.
New dimpling on the legs stops air attaching to the fabric so that air comes off cleanly – it also allows for better print quality too. There's a new leg gripper that features a lie-flat raw-cut edge but now has vertical silicone stripes to keep it in place without restricting stretch and leg movement.
Castelli has updated the seams to improve the fit and make the short look even cleaner. The team has re-engineered the bib straps with new lighter, more breathable material so they stay cooler, lie flatter and are more durable. They also look fantastic with a new pinstripe design. A new loop for race radio microphone was added at the request of team riders.
The Free Aero Race 4 Bibshort also features Castelli's brand new Progetto X2 Air Donna 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 the 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's doesn't fold while the finish is the softest ever on a pair of Castelli shorts for luxurious comfort next to the skin.
