There's a new leg gripper that still features a lie-flat raw-cut edge but now has vertical silicone stripes to keep it in place without restricting stretch. The new fabric allows for better print quality for your custom team production, the same as Team Ineos will use in 2019. We've updated the seams to improve the fit and make the short look even better on the body. We've re-engineered the bib straps with new fabrics and construction so they stay cooler, lie flatter and are more durable. The revised Free 3 Aero Race Bibshort also receives the updated Progetto X2 Air seamless seat pad featuring the softest surface fabric you've ever felt in a seat pad. You'll be glad we ignore the old saying, If it ain't broke, don't fix it. - Vortex dimpled fabric on legs for aero performance - Forza fabric on inner legs with 38% Lycra content for perfect fit - Stripe mesh engineered minimalist bib construction keeps you cool - Giro4 leg gripper elastic for better grip distributed over larger area - Doppio V construction in front for increased support and comfort - Flat-lock stitching - Progetto X2 Air Seamless seat pad

Castelli Premio 2 Bibshort
$279.99
This short is the result of decades spent working to make long hours in the saddle ever more comfortable. The fabric is our high-stretch Forza fabric. The 38% Lycra content means that it’s gently compressive while never binding. And it maintains an insanely soft hand. The nearly seamless construction is derived from our Body Paint shorts, which debuted a decade ago and started the trend of reduced seams while maintaining remarkable fit. Nothing to rub or break. The renowned Progetto X2 Air Seamless seat pad gets an update in this season with a new skin care layer that features a remarkably soft new surface fabric and more stretch, which allows us to eliminate the front triangle. We also obsessed over every other little detail, like the new bib construction and even new silicone logos that stretch with the base fabric and recall the logo location of the first Castelli Aero Short from the late ’70s, the short that started it all. - Forza fabric with 38% Lycra content for a perfect fit - Dual-layer lumbar support band keeps shorts locked in place around waist - Reduced seaming for more comfort - Raw-edge leg ending with vertical silicone grippers - Mesh back with bonded 2-layer bib straps - Silicone Castelli logos - Progetto X2 Air Seamless seat pad
