Pure and versatile: two words that perfectly define the 765 OPTIMUM+. Two brands come together to compose almost all of this versatile carbon fiber road bike: Shimano takes care of the groupset and Ultegra disc brakes, while LOOK handles everything else, from the carbon frame to the carbon wheels.

Road cycling? Definitely—but not only. The strength of the 765 OPTIMUM+ lies in a rock-solid versatility that will take you anywhere. Its components, endurance-oriented geometry, and meticulous blend of carbon fiber are designed to take on the straightest of roads and the hilliest of trails.

Originally equipped with road wheels and tires, this is a bike that easily transforms into an off-road warrior thanks to wide tire clearances, both front and rear. The full-carbon fork and 3D Wave seatstays can accommodate tire widths up to 700x42. Do you need more? No problem: the 765 OPTIMUM+ is also compatible with 27.5-inch MTB wheels and 650x2.1 tires.

Head for new horizons in comfort and with confidence.
