Look 765 Optimumvs785 Huez

Picture yourself winding through a long, high-speed descent on a bumpy country road or grinding up a sustained mountain pass. The Look 765 Optimum would glide through the imperfections, providing unwavering stability and comfort, almost like a luxury sedan. In contrast, the Look 785 Huez, while still remarkably comfortable, would engage you more directly with the road, urging you to push the pace with its responsive, communicative chassis.

Overview

The Look 765 Optimum and 785 Huez, both from the venerable French marque, carve out distinct but overlapping niches in the road bike market. The 765 Optimum is a dedicated endurance machine, built from the ground up to provide maximum comfort and unflappable stability for long distances and varied road conditions. It’s designed to be a reliable, fatigue-reducing companion for riders who prioritize a smooth, secure ride over aggressive race-day dynamics. Conversely, the 785 Huez is primarily a performance-oriented climbing bike, but with a surprising breadth of capability that extends far beyond its initial categorization. While engineered for responsiveness and efficiency on ascents, reviewers consistently praise its sublime ride quality and long-distance comfort, positioning it as a highly versatile road machine. This makes the Huez a strong contender for riders who want race-bred characteristics without the harshness often associated with pure climbing bikes, capable of handling everything from spirited club rides to epic multi-day tours. Interestingly, the 765 Optimum, the designated endurance model, is priced higher than the 785 Huez at comparable Ultegra Di2 builds, suggesting a premium is attached to its advanced comfort-enhancing frame design.

Ride and handling

The Look 765 Optimum lives up to its endurance billing, making comfort its undisputed champion. Reviewers unanimously call its ride quality exceptional, with Cyclonline stating that the frame’s ability to "absorb road vibrations and bumps is truly remarkable," allowing the bike to "glide over rough surfaces." This means it minimizes fatigue, with Mapdec Cycle Works finding it "super stable in a straight line for cruising no matter how tired I was," even when hitting "little potholes and little bumps in the road." In terms of handling, the 765 Optimum is a picture of stability. Cyclonline describes it as a "stable locomotive on rails—it's fast, secure, and well-braked," and notably "minimally affected by crosswinds." This unwavering composure translates to immense confidence, particularly on descents. However, this stability comes with a trade-off in agility; it's "not the most agile bike and can feel a bit slow to turn into corners," and Mapdec noted it "definitely understeers," requiring a "slower entry speed into a corner." Despite this, for its intended purpose, this predictable behavior is a desirable compromise. The 785 Huez, while a climbing bike, delivers a ride quality that Cycling Weekly calls "sublime" and Road.cc a "masterclass in both design and manufacturing" for its ability to be both stiff and compliant. Its comfort is noteworthy, with Road.cc reporting "no fatigue in my wrists or lower back" on long rides, and Cycling Weekly completing a 1,000-mile journey across France without "one aching joint." This suggests the Huez effectively dampens road buzz, even with narrower tires. Handling on the 785 Huez is a captivating blend of nimbleness and stability. Road.cc praised its "impressively responsive" feel when pedaling hard and a "talkative" setup that provided "huge amounts of feedback" through tight corners and fast sections. This makes it engaging and confidence-inspiring on descents, with Cycling Weekly noting a "reassuringly high level of grip from the front wheel." The Huez also maintains its composure remarkably well, feeling "resolutely stable" in crosswinds even with deeper section wheels, striking an impressive balance between race-ready quickness and predictable control.

Specifications

Examining the selected Ultegra Di2 builds, the Look 765 Optimum carries a price tag of $7,500, while the 785 Huez Ultegra Di2 / R50D is offered at $6,500. This is a significant $1,000 difference, with the endurance-focused 765 being the more expensive option despite both featuring similar electronic Ultegra groupsets. This pricing strategy suggests Look invests more in the 765's frame technology for comfort, or perhaps reflects its positioning for a broader appeal, but it's a noteworthy gap that impacts perceived value. Both bikes use Shimano's reliable 12-speed Ultegra Di2 groupset, ensuring consistent, precise shifting and powerful hydraulic disc braking across their selected builds. They also share the modern T47 bottom bracket standard, a choice lauded by reviewers for its blend of stiffness and threaded system reliability. However, differences emerge in wheelsets and tires: the 765 Optimum ships with LOOK R 38 D Carbon Tubeless wheels and wider Hutchinson Fusion 5 Tubeless Ready 700x30 tires, leaning into its comfort and grip mandate. The 785 Huez, in its selected Ultegra Di2 build, comes with deeper LOOK R50D wheels and slightly narrower Hutchinson Fusion 5 Performance Tubeless 700x28 tires, hinting at a more aero-conscious, speed-focused approach that aligns with its climbing/versatile identity. Cockpit components are largely consistent, with both bikes featuring LOOK LS3 Alloy stems and handlebars, though the Huez specifies 'Aero' bars. The 765 Optimum gets a slightly more premium LOOK LS1 Carbon Super Light 27.2mm seatpost, compared to the LS2 Carbon found on other Huez builds, further reinforcing the 765's comfort-enhancing intentions. Overall, while both bikes offer solid, functional finishing kits, the 765's higher price for similar drivetrain components and a slightly lighter carbon seatpost implies its value is heavily weighted on its frame technology and the enhanced ride experience it provides, especially when considering the 785 Huez's 105 Di2 build was criticized for its value against competitors.

Geometry and fit comparison

At size Medium, the Look 765 Optimum and 785 Huez present two distinctly different approaches to rider positioning and handling dynamics. The 765 Optimum is designed for an unequivocally upright and relaxed fit, evident in its significantly higher stack of 582.0mm compared to the 785 Huez's 567.3mm, a difference of +14.7mm. This is coupled with a shorter reach (379.0mm vs. 385.6mm, a -6.6mm delta) and a much longer headtube (170.0mm vs. 140.7mm, nearly 30mm taller). This geometry suits riders prioritizing comfort, those with less flexibility, or anyone looking to spend long hours in the saddle with reduced strain on their back and neck. The handling geometry further accentuates these differences. The 765 Optimum features a notably slacker head tube angle of 70.8° and a generous trail figure of 67.0mm. This combination creates a supremely stable front end, contributing to its "stable locomotive" feel but also leading to slower, more deliberate steering. Its longer 415.0mm chainstays further enhance straight-line stability. This setup is ideal for riders who value predictability, especially on rough roads, high-speed descents, or in crosswinds, even if it means sacrificing some of the snappy responsiveness of a race bike. In contrast, the 785 Huez, even with a "comparatively elevated stack" for a climbing bike, offers a more aggressive, race-oriented position. Its steeper 73.0° head tube angle and shorter 59.3mm trail figure result in quicker, more responsive steering. Paired with shorter 410.0mm chainstays, this creates a nimble and engaging ride, allowing the bike to react swiftly to rider inputs and carve through corners with precision. The Huez's geometry is better suited for riders who prefer a more stretched-out, aerodynamic posture and demand immediate handling feedback for spirited riding, technical descents, and quick accelerations. For riders with good flexibility and a desire for an interactive ride feel, the 785 Huez provides that connection to the road. Ultimately, these geometry choices perfectly align with each bike's intended purpose: the 765 Optimum for unwavering comfort and stability on endurance rides, and the 785 Huez for responsive, dynamic performance that still manages to be comfortable over long distances. The 765 is a great fit for riders who want to be more 'on' the bike in a relaxed posture, while the 785 allows riders to be more 'in' the bike, ready for action.

Who each one is for

Look 765 Optimum

The Look 765 Optimum is purpose-built for the rider who prioritizes enduring comfort and unshakeable stability on their road excursions. If your weekends involve long, steady centuries on variable road surfaces, or you're planning a multi-day tour where fatigue management is paramount, this bike is a strong contender. It's for the cyclist who values feeling "super stable in a straight line for cruising" even when tired, and who approaches descents with an appreciation for predictable, confidence-inspiring handling rather than aggressive, sharp turns. This rider might be less concerned with outright climbing speed or lightning-fast accelerations, instead valuing a bike that efficiently carries them up sustained gradients in a comfortable, seated position, allowing them to cover "no limits to the miles you can cover" with ease.

Look 785 Huez

The Look 785 Huez targets the rider seeking a performance-driven road bike that doesn't compromise on comfort, even on the longest days. This is for the cyclist who loves to tackle challenging climbs with a responsive, eager machine, yet still expects a "sublime ride feel" that isolates road buzz on rough patches. If you enjoy spirited club rides, revel in fast, technical descents where a "talkative" frame provides ample feedback, and appreciate a nimble feel without nervousness, the Huez delivers. It’s ideal for the rider who wants a versatile partner for varied terrain—from flat stretches where it "surges forwards eagerly" to mountain passes—and desires an engaging, connected riding experience that can still swallow 1,000 miles in comfort.
