Colnago V4RsvsLook 795 Blade RS

The Colnago V4Rs features a 71.5-degree head angle on the size 485, a surprisingly slack choice for a Tour de France winner that favors high-speed stability over low-speed twitchiness. In contrast, the Look 795 Blade RS is built with such extreme bottom-bracket rigidity that it can feel punishingly harsh on any road surface less than perfect.

Overview

Both brands are heavy hitters in the WorldTour peloton, with Colnago supporting UAE Team Emirates and Look powering Cofidis. The V4Rs is Colnago's versatile racing tool, designed to be as effective climbing the Galibier as it is sprinting for a stage win, whereas the 795 Blade RS marks a total departure from Look's previous focus on eccentric, integrated aero shapes. It is now a focused racing machine that aims for raw power transfer and a grounded feel, throwing away the complex aesthetics of past 795 iterations for a more traditional look. Colnago relies on its Real Dynamic Stiffness testing and pro feedback from Tadej Pogačar to find a balance of attributes, while Look admits it favored efficiency and handling over pure wind-tunnel metrics. Both bikes sit in the five-figure price bracket, but they offer different identities. The V4Rs feels like a refined machine where the parts work together to damp road noise, whereas the 795 Blade RS is a stiff instrument of speed that favors zero-flex efficiency at every junction.

Ride and handling

The V4Rs is a specialist on the descents. Its slacker front end makes it unerringly poised when things get fast and twisty, offering a level of confidence on mountain passes that steeper, more nervous race bikes often lack. It feels surefooted, with a ride quality that filters out road buzz well for such a stiff frame. It isn't a soft bike—it’s firm and communicative—but it doesn’t beat the rider up over a four-hour day, providing what reviewers call a "nicely pitched level of comfort." The Look 795 Blade RS is the opposite: it's whip-crack sharp. If you stand up and stomp, the response is instantaneous, likely due to that massive, overbuilt bottom bracket junction. However, that rigidity becomes a liability on broken pavement. One reviewer noted it felt "shaken quite violently" on typical rough roads. It is a bike designed for the smooth, pristine asphalt of the European racing circuit, and it demands a rider who is willing to trade physical comfort for raw power transfer. Handling on the Look is agile and light, which is brilliant for technical turns, but it can feel prone to buffeting in crosswinds. The V4Rs handles with a more neutral, "fun side of neutral" character. It corners as if on rails once the line is chosen, but it doesn't encourage mid-corner corrections as eagerly as the Look. The Look is for the crit circuit; the Colnago is for the mountain pass.

Specifications

Looking across the builds, Colnago makes several smart, durability-focused choices that Look misses. Every V4Rs uses CeramicSpeed SLT headset bearings, which feature a solid polymer lubricant to prevent the ingress of dirt—a significant win given the internal routing makes headset service a nightmare. They also use a T47 threaded bottom bracket, which offers the stiffness of an oversized shell without the creaking issues common in press-fit setups. Look’s builds are often less complete out of the box. Most Shimano-equipped 795 Blade RS models lack a power meter, a glaring omission on a bike costing well over $10,000. While they use Corima wheels, the rim profiles can feel dated. The narrow 21mm internal and 26mm external widths often result in being spec'd with 25mm tires, which limits the bike’s ability to find compliance. Colnago, by contrast, frequently ships with wider Enve or Shimano wheels and has frame clearance for 32mm tires, allowing for a modern, high-volume setup.

Geometry and fit comparison

For riders caught between sizes, the Colnago is significantly more accommodating. In the selected sizes, the V4Rs has a stack height of 539mm—nearly 14mm taller than the Look’s 525.2mm. This makes the Colnago a more viable option for riders who lack the flexibility of a professional racer but still want a world-class frame. Both bikes share an identical 74.5-degree seat tube angle, which pushes the rider forward over the cranks for power transfer. Handling geometry shows where the identities diverge. The Look aims for a nimble, agile front end with a trail figure of 59.3mm. The Colnago uses that slacker head angle to achieve a longer trail of roughly 63mm with 28mm tires. In practice, the Look feels faster and more eager to turn in at low speeds, while the Colnago is the bike you want when you're tucked in at 70km/h. It trades some low-speed flickability for high-speed stability.
