Performance Perfected
After 12 years of evolution and millions of miles of on the road testing, Castelli have once again pushed the boundaries of cycling comfort and performance. It all starts with the seat pad - the Progetto X2 Air inside the Free Aero Race 4 Bib Shorts is softer and more flexible than ever.
Progetto X2 Air Seamless Seat Pad
The first contact point against the skin is the super-soft upper skin-care material. It's now seamless and even softer than previous generation pads. The next layer, Castelli’s infinitely variable thickness padding, imparts just the right level of support where you need it - thicker under the sit bones and thinner on the sides and under the perineum. The results are outstanding comfort with reduced bulk.
Lastly, to really push home superior comfort levels, perforated viscous padding is added under the highly sensitive ischial and perineum pressure areas, offering luxurious support when you're on the saddle for hours on end.
GIRO4 leg grippers
Next, GIRO4 leg grippers get enhanced stretch and yet are grippier than previous versions so the pressure is spread wider but without any loss of traction on the thighs. A lie-flat raw edge provides a smooth transition between skin and shorts and the vertical silicone grippers hold firm without exerting excess pressure.
Improved Bib Straps
Lastly, the Stripe Mesh straps are reduced in weight and yet offer enhanced support, in all honesty, you'll barely notice they're there, but that's the whole point. Castelli have also used a more breathable material meaning even greater comfort when the pace picks up, wicking away sweat before it can pool and cause discomfort. Pro riders wanted a radio pocket too, now it's lie-flat and unobtrusive, a real pro-ready design.
Pro Performance
With many Pro riders clocking up 30,000kms a year in their Castelli shorts they're very exacting with regards to their kit. Castelli listens, learns, tweak and improves their kit with Pro-rider feedback. As soon as you pull the Free Aero Shorts on you'll soon feel the comfort such input delivers.
