Depending on speed, course, and the jersey being compared, a TT jersey can save 30-90 seconds over a 40K time trial compared to a standard club-fit jersey, and 10-30 seconds compared to an aero road jersey. Over an Ironman bike leg, the savings can be 2-5 minutes versus a standard jersey. These gains come from reduced aerodynamic drag, not from any physiological benefit.
