The Castelli Free Aero Race 4 Team Bib Shorts draw on 12 years of aero bib short evolution to deliver ride perfection. The Free Aero Race 4 Bib Shorts feature some dramatic, performance-enhancing changes.
Dimpling on the legs stops air from attaching to the fabric so that air comes off cleanly and allows for better print quality too. The leg gripper features a lie-flat raw-cut edge with vertical silicone stripes to keep it in place without restricting stretch and leg movement.
The bib shorts' panelling has improved fit for support while making the shorts look even cleaner. Castelli has re-engineered the bib straps with a lighter, more breathable material so they stay cooler, lie flatter and are more durable. A new loop for race radio microphone was added at the request of team riders.
The Bib Shorts use Castelli's Progetto X2 Air Seamless seat pad. The pro-level seat pad consists of two separate layers: a soft stretchy layer that sits next to your skin and prevents any rubbing, and a perforated cushioning layer with two separate density foams along with breathable perforated gel inserts.
