Castelli 2014 Free Aero Race Bib Shorts - The Castelli Free Aero Race Bib Shorts benefits from years of constant refinement, including 4 years of Pro racing testing - Three fabrics provide technical attributes unmatched by others: 1) Action Micro Fabric in the saddle contact area provides durability and helps maximise the life span of the bib shorts, 2) Energia Micro Fabric on sides and back for outstanding stretch and excellent return, 3) Breathe Micro Fabric in front provides enhanced breathability. - Progetto X2 Air Seat Pad for famous X2 comfort and improved air flow. Constructed in two components, each dedicated to a specific purpose. The thickness of the pad is engineered to place the padding where you need it most for maximum comfort. - The updated Giro3 integrated leg grippers have been intelligently fashioned so that the grip material has been knitted directly into the short. Instead of stitching silicone elastic to the short, Castelli knit the grip material directly into the short in a 5cm-wide band that gently compresses while securely holding the short in place. It lies completely flat for improved aerodynamics. - Famous free bib keeps your chest free to avoid overheating. The shape of the bib straps allow for a very wide opening on the front torso that dips down to the waist. You won't feel hindered by the straps and you'll really appreciate the open-air feeling - 2 rear reflective inserts Bike Radar rated 4/5 "Expensive, but fit and seamlessly integrated gel padding makes these ProTour proven bibs worth it" "With the proliferation of carbon fibre, most major bike manufacturers who support ProTour teams have found a way of providing everyday riders with the same designs used in top-level racing, if not the exact layups and materials. When it comes to clothing, however, most top teams still have their kits custom made to the dimensions of each rider."
