Cervelo, the brand arguably responsible for popularizing the modern aero road bike, has pulled back the curtain on a their latest iteration. The S5 will be the weapon of choice for Garmin-Cervelo team riders at the upcoming Tour de France. It’s a faster, stiffer and lighter frame than the S3, says Cervelo. The S3, however, is no slouch as the winner of our Editors' Choice Race Bike award and the platform upon which Thor Hushovd won the 2010 World Championships. The S5 may not win any awards for beauty, but Cervelo thinks it's the world’s fastest frame approved for professional racing.
