This is the same Aero Race Jersey that wins races with the Garmin-Cervélo team — the fastest jersey in the peloton. Only the colors have changed. Two-thirds of aerodynamic resistance is created by the rider, so even the smallest gains here can make a big difference. In wind tunnel testing, the Aero Race saved 10 watts when riding on the hoods at 40km/h (25mph). That translates into 40 seconds saved every hour compared to a standard jersey. So either you can ride faster or with less effort—your call.
