Origin
Look unveiled the original 765 in 2015 as the French marque's entry into the sportive/endurance segment, notable for Carboflax — a layer of natural flax fibre sandwiched between carbon at the chainstays and fork to damp road vibration, a technique borrowed from aeronautics and motorsport. The model was relaunched in December 2022 as an all-new 765 Optimum: a comfort-first endurance platform built around '3D Wave' flattened carbon stays, 34 mm tyre clearance, recessed mudguard mounts and a threaded T47 bottom bracket. Look markets it under the tagline 'the alchemy of endurance'.

Specifications
- Frame
- Full carbon endurance frame (HM/HR carbon) with '3D Wave' flattened seatstays for +15% vertical compliance; threaded T47 bottom bracket; clearance up to 34 mm tyres (700×42 on road wheels per Look). Earlier 765 (2015) generation used Carboflax — a flax-fibre layer sandwiched in carbon at chainstays/fork for vibration damping.
- Weight
- kg
- Drivetrain

The verdict
+Strengths
- Outstanding ride comfort and compliance over long distances (3D Wave stays + wide tyres) — praised for long-training-ride smoothness
- Stable, confidence-inspiring handling — 'a locomotive on rails', secure even at speed and on wet/damaged roads
- Genuinely practical endurance design: 34 mm tyre clearance, mudguard mounts, threaded T47 BB
- Lightweight for the category (frameset ~1,400 g; full bikes ~8.5-8.8 kg)
−Weaknesses
- Relatively high weight and slack head-tube angle make it feel less efficient on climbs
- Several stock components feel like they could be upgraded to unlock the frame's potential
- Expensive for the spec level, especially the Optimum+ builds, versus established rivals
- Mudguard mounts only accept Look's own proprietary mudguards — limited compatibility
