2018 Look 765 Optimum RS - Ultegra Di2

The Look 765 Optimum RS Shimano Ultegra Di2 is built for long and fast rides thanks to its unique vibration damping chainstays and fork that smooth rough roads. By combining layers of flax linen and carbon fibers, Look created a lightweight ultra endurance bike that features a shorter top tube and taller head tube for more comfortable body positioning. The 765 Optimum RS includes Shimano Ultegra brakes for utmost control in all kinds of weather and over all types of roads, while an incredibly intuitive Shimano Ultegra R8050 Di2 11-speed drivetrain offers tremendous value and dependability no matter how you ride, and Mavic Ksyrium wheels paired to grippy Continental Ultra Sport tires give you the confidence to push your limits on every ride.
