The Alchemy of Endurance

The LOOK 765 Optimum Ultegra Di2 is a light and fast endurance-oriented bike. Incredibly versatile, it offers a perfect balance of performance and comfort. A distinctive, multi-talented road bike, designed for ultra-distance racing as well as for your everyday rides.

The 765 Optimum is the ideal bike for your daily spins as much as your next cycling challenge. Designed in France by LOOK's team of passionate engineers, it offers a compromise between stiffness and flexibility that will allow you to fully enjoy the ride as the miles build up.

Why Choose Between Comfort And Performance?

The 765 Optimum was created to offer a perfect balance of comfort and performance, which comes in the form of a unique, hyper-versatile frame developed in the LOOK laboratories. Its design combines various endurance-specific carbon fibers, a studied geometry and dedicated technologies that allow you to combine effort with enjoyment on every single ride.

Designed to glide over rough surfaces and face all challenges, the 765 Optimum blends several different carbon fibers, various weaves and specifically-chosen materials to increase comfort.

The seatstay design features their 3D WAVE technology, which provides the bike with optimized lateral efficiency and unparalleled comfort thanks to its specific shape and choice of carbon fibers.

Assertive Design Ready For Any Challenge

As ultra-distance enthusiasts will without a doubt agree, an endurance bike must be efficient to go further, for longer. The 765 Optimum relies on a responsive, lightweight frame (1400g/49oz for the frame + fork) and clever solutions borrowed from top-of-the-range models in the LOOK Cycle range.

The LOOK LS3 stem was developed for optimal cable and brake hose routing from the handlebars to the frame. The gearing cables and brake hoses are conveniently and efficiently routed and secured under the stem.


  • Perfectly-balanced carbon frame: lightweight and responsive for everyday rides, it also offers a geometry and comfort geared toward long-distance riding.
  • Unique design: by combining different carbon and glass fibers with innovative materials, LOOK have achieved an optimal balance of stiffness and flexibility.
  • 3Dwave technology: absorb the shocks and vibrations of the road like you're riding a real flying carpet.

  • Incredible versatility : designed to accommodate tires up to 34mm, the bike can also be fitted with mudguards for your winter rides or daily commutes.
