AERO SLEEVES FOR AERODYNAMIC GAINS. If you have a keen eye, you'll have noticed the lines running down the arms of our pro riders when they race TTs. These aero ribs are our Bolero sleeves — here in a short-sleeve version. The ribs create aerodynamic trip strips, making our Aero Jerseys and San Remo Speedsuits even faster.
