The fastest jersey in the Pro Tour!Two Thirds of aerodynamic resistance is created by the rider and only 13 from the bike. So even small gains here can make a big difference. In fact, testing from the San Diego windtunnel shows that the Cervlo Aero Race Team Jersey saves 10 watts when riding with your hands on the hoods at 40 kmh. That translates into about 36 seconds saved every hour. But since drag is exponential, that means you get double the savings at 57 kmh, and 4 times at maximum sprint speed of 80 kmh. Aero technology saves 10 watt s at 40kmh compared to a normal race fit jersey.
