Hit the gas and the Kestrel RT1000 SL will respond with agility, sweeping though the corners with confidence and roaring up the road with aerodynamic efficiency. Yet, power and efficiency means little if you're not comfortable. Kestrel knows carbon, as the first manufacturer of an all-carbon frame, and they've put decades of experience into making the RT1000 one of the smoothest riding bikes on the market. The RT1000 was built with an endurance geometry that employs a longer head tube compared to some full-race machines, keeping you in a comfortable position you can maintain as the miles add up. Shimano Ultegra Di2 takes care of the electric drivetrain for lightning quick shifts, while a compact crank lets you continue to spin when the tarmac turns vertical. A set of aerodynamic Oval Concepts wheels, wrapped in Vittoria tires, completes this bike, making it fit to fly. Available in 47, 50, 53, 56, 59 and 62cm.
