With the 765 OPTIMUM RS, LOOK's engineers have created an ultra endurance and very lightweight bicycle. To accomplish this, they tested a new geometry and carbon technology. The top tube is shorter, and the cockpit is raised up as a result of the headset being positioned higher. The « CARBON + FLAX FIBER » technology combines carbon and flax linen fibers, which filter vibrations, providing a major benefit on long endurance rides.
