The Castelli Free Aero Race Bib Shorts have also been tested to bib short perfection by Cervélo’s Test Team. Energia fabric on the sides and back of the bib shorts stretches horizontally, giving compression to muscles without constricting movement. The Breathe Micro front panel allows for ventilation, and Action Micro fabric resists abrasion in the saddle area so they last through the ProTour season.

• Wide bib straps keep chest cool and nipple chafing to a minimum
• No inner leg seam
