Metolius Ultralight Three Cam Unit Review

Grit & Gear: Testing the Metolius Ultralight Three Cam Unit

As an equipment specialist with over a decade of hands-on experience across diverse environments – from dusty workshops and sterile labs to rugged outdoor expeditions and demanding field applications – I approach gear with a critical, yet appreciative eye. My journey led me to the Metolius Ultralight Three Cam Unit, a piece of climbing hardware that has consistently earned its reputation in the vertical world. This particular unit, a staple for many climbers, promised a blend of lightness and functionality, a combination crucial when every ounce matters.

My need for these specific units arose from a recurring challenge: finding reliable, lightweight protection for delicate, shallow placements on a recent alpine project. My existing rack, while robust, felt cumbersome and sometimes inadequate in the nuanced placements that define challenging routes. I was looking for something that offered confidence without adding significant bulk to my pack.

Initial impressions of the Metolius Ultralight Three Cam Unit were positive. The CNC-machined aluminum felt solid, and the overall construction exuded a meticulous build quality. The narrow head width was immediately apparent, suggesting excellent potential for fitting into tight cracks. My previous gear relied on older designs, so this modern interpretation felt like a significant upgrade in design philosophy.

I had briefly considered other micro-cam options, but their perceived weight or less refined cam lobe geometry steered me away. The promise of Metolius’s Direct Axle Technology (DAT) was the real draw, suggesting a leap in efficiency and weight savings. My immediate reaction was one of informed curiosity, a sense that this gear might indeed solve the specific problems I was encountering.


Real-World Testing: Putting Metolius Ultralight Three Cam Unit to the Test

My testing ground for these units was the granite climbing areas of Yosemite and the unforgiving limestone of the Gunks. I specifically sought out routes with pockets, shallow fissures, and outward-flaring cracks – placements that often make or break a climb. The units were subjected to repeated placements and potential loadings, not just for critical falls but for the dynamic art of lead climbing.

Performance in various conditions was surprisingly consistent. Even in dusty, chalked-up cracks, the cam lobes maintained their grip without excessive dirt accumulation on the DAT mechanism. The color-coding system proved invaluable for quick identification, even in low light or when my mind was racing through the next sequence of moves.

Ease of use was a standout feature from the very first placement. The Range Finder system, a subtle but ingenious addition, provided an immediate visual cue, ensuring I was choosing the appropriate cam size for the placement. This eliminated much of the guesswork, particularly in the smaller sizes where subtle differences in diameter can mean the difference between a bomber placement and a risky one.

There were no significant issues or surprises after initial use; rather, it was a series of pleasant confirmations. The U-shaped body design offered a surprisingly solid feel when pulling on the cam, and retraction was smooth. It quickly became evident that these weren’t just lighter versions of existing cams, but a thoughtfully re-engineered tool.

First Use Experience

The initial placements felt familiar yet refined. The narrow head width was a revelation, allowing me to access cracks that had previously required intricate nut placements or felt too precarious for micro-cams. I tested these units on a challenging 5.11 crack route where precise, small protection was paramount.

Conditions ranged from warm, sunny rock faces to cooler, shaded overhangs. The Metolius Ultralight TCUs performed admirably across this spectrum. Their weight savings were noticeable on longer approaches and even more so when reaching for them on the second or third rack.

I found the Range Finder system to be incredibly intuitive. It’s a simple visual aid, but it significantly speeds up the placement process. This was particularly helpful when transitioning quickly between different crack sizes.

The only minor quirk was getting used to the slightly different feel of the sling material. While the 13 mm Monster Sling offers excellent durability, it has a bit more stiffness than pure Dyneema slings. This is a trade-off for its blended construction and is more a point of note than a genuine detractor.

Extended Use & Reliability

After several months of consistent use on everything from sport climbs to multi-pitch trad adventures, the Metolius Ultralight Three Cam Unit has held up exceptionally well. I’ve subjected them to numerous moderate falls and countless practice placements.

Durability has been impressive. Despite being dropped on rock and concrete on occasion, there are no significant scuffs, cracks, or signs of weakness. The cam lobes remain sharp and grippy, and the DAT mechanism continues to operate smoothly.

Maintenance is straightforward. A quick rinse in fresh water after a day at the crag, followed by air drying, is usually all that’s needed. I occasionally use a small brush to clean out any residual grit from the cam faces.

Compared to my older rack of similar-sized cams, these Ultralights are clearly lighter and feel more purpose-built for modern climbing. While some premium, high-end units might offer slightly more exotic alloys or wider ranges, the balance of weight, performance, and price offered by these Metolius units is exceptional.

Breaking Down the Features of Metolius Ultralight Three Cam Unit

Specifications

The Metolius Ultralight Three Cam Unit is a testament to efficient engineering. Its core construction utilizes CNC machined 7075-T6 aluminum, a high-strength alloy known for its durability and relatively low weight. The standout feature is the Direct Axle Technology (DAT), which allows the lobes to pivot directly on the axle, significantly reducing the internal components and thus the overall weight.

This DAT design contributes to the 1.4 oz weight for the unit, making it one of the lightest in its class. The narrow head width, a critical design choice, allows for placement in tighter cracks than many competing models. The cam lobes themselves are designed with an optimized cam angle for more outward force and feature wider cam faces for more grip, maximizing holding power.

The integrated 13 mm Monster Sling is a blend of Dyneema and nylon, offering a good balance of strength, abrasion resistance, and a slight stretch to absorb impact. The Range Finder system uses color-coded indicators on the sling and the cam lobes themselves, providing a visual guide to ensure the cam is optimally placed within its range.

Performance & Functionality

The primary job of the Metolius Ultralight Three Cam Unit is to provide secure, reliable protection in a variety of rock crack sizes. In this regard, they excel. The optimized cam angle and wider lobe faces translate directly into superior holding power.

The strengths of these cams lie in their lightness and their ability to fit into smaller or more awkward placements. The DAT design genuinely minimizes the unit’s footprint in the crack. However, their diminutive size also means they are best suited for smaller cracks, and using them in very wide or flaring placements would be outside their intended design parameters.

These units meet and often exceed expectations, especially for climbers prioritizing weight savings without compromising essential security. The Range Finder system is a particularly well-executed feature that boosts confidence during placement.

Design & Ergonomics

The build quality of the Metolius Ultralight Three Cam Unit is immediately apparent. The CNC machining results in precise tolerances and a clean finish. The U-shaped body design provides a solid point of contact for your hand during placement and retraction, offering excellent control.

Ergonomically, these cams are a pleasure to use. The trigger mechanism is smooth and responsive, and the color-coded sewn slings and tubing make them easy to identify quickly on your harness. The narrow head width, while excellent for placement, can sometimes make them a little fiddly to grab for retraction if you have larger fingers, but this is a minor point.

The machined cam stops are a subtle but important detail, preventing over-rotation and contributing to the unit’s overall durability. Every aspect of the design seems to have been considered for practical application on the rock.

Durability & Maintenance

The Metolius Ultralight Three Cam Unit is built for repeated use and abuse. As a piece of climbing hardware, its intended lifespan is long, assuming proper care and avoiding truly catastrophic loadings. The robust aluminum alloy and the well-engineered DAT system suggest longevity.

Maintenance is minimal. As mentioned, a simple rinse and dry after use is generally sufficient. Inspecting the sling for any fraying and ensuring the lobes move freely are standard practices.

Potential failure points, like any mechanical device, would likely stem from extreme impact or improper use. However, the CE/UIAA certification and Metolius’s reputation for quality control provide a high degree of confidence. The hand-built inspection and individual testing to one-third of rated strength at their Bend, Oregon facility is a significant reassurance.

Accessories and Customization Options

The Metolius Ultralight Three Cam Unit comes as a self-contained unit. There are no additional accessories that are typically bundled with these cams themselves, as they are designed to be integrated into a climber’s existing rack. However, Metolius does offer a range of other climbing hardware and accessories that complement their cam designs.

While there are no inherent “customization” options for the cam unit itself (beyond choosing the size and color), the 13 mm Monster Sling is a significant feature. This blended Dyneema/nylon sling offers a robust alternative to pure Dyneema, providing slightly better durability and a touch more friction for racking on carabiners. The color-coded sewn slings are a form of immediate visual customization for quick identification.
