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.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are some benefits of electronic shifting that you don't want to miss.
Electronic shifting systems use powerful servo motors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with surgical precision and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you'll never have to replace a derailleur cable ever again.
