With the 765 OPTIMUM RS, LOOK 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 FIBRE » technology combines carbon and flax linen fibres, which filter vibrations, providing a major benefit on long endurance rides.
The 765 is the benchmark for high-end endurance bicycles. Its High Modulus carbon fibre makes it, in addition its comfort properties, an ultralight weight bicycle.
CARBON + FLAX FIBRE TECHNOLOGY
This technology is the result of the combination of 2 types of fibres from different materials: carbon (High Modulus) and flax linen fibres. The carbon is joined with the flax to filter the vibrations transmitted by more or less quality roads, therefore increasing the comfort level of the bicycle. LOOK strategically applied this technology to the fork and chainstays as it is these 2 places that react immediately to road impacts. Combining the linen adds the wonderful and natural property of vibration dampening.
Sandwiched between two carbon sheets, it increases the overall performance of the bicycle: the cyclist who battles fewer road vibrations will conserve all his or her energy for pedalling and bike handling; a real benefit for long endurance rides.
