Crush endurance mileage without the punishing road buzz that drains your legs and numbs your hands. Traditional race geometries force an aggressive tuck that compromises lower-back comfort on century rides, while overly compliant endurance frames feel sluggish out of the saddle. The LOOK 765 Optimum 105 Di2 blends multi-modulus carbon layers with Look's signature 3D Wave stays to filter high-frequency tarmac harshness, delivering a refined "flying carpet" ride quality without sacrificing lateral bottom-bracket stiffness.
Engineered for gran fondos, all-day alpine adventures, and fast weekend group rides, this build pairs the seamless precision of Shimano 105 Di2 12-speed wireless shifting with a versatile 34mm tire clearance. Integrated cockpit routing keeps aerodynamic lines clean, while the Look R50D wheelset slices through rolling terrain, letting you push harder, ride farther, and conquer high-elevation passes with absolute composure.
