Cervelo S3 Ultegra (2015)

The world championship-winning S3 is back… and even better than before. A completely redesigned chassis combines new, more robust airfoil sections with a rear triangle borrowed from our revolutionary RCA road frame. Future-Proof cables allow for easy set up of internal electronic, mechanical, or hydraulic shifting and braking lines. Increased clearance allows you to choose up to a 700x25mm tires. Stiffer, better-riding, aero as ever. And all with zero weight penalty.
