You forget it is on your foot.

At first light, on a long uphill run, you’ll barely feel the ski under your feet from the very first few meters. Its narrow 89-mm waist and carbon-reinforced paulownia core ensure true lightness on the ascent while maintaining crisp edge grip on the descent. This model is designed to tackle elevation gain and cover mile after mile without wearing you out.

How do you measure your ski boots?

The shape

Light up, honest down.

The Ubac 89 combines a paulownia core with a carbon weave to provide stiffness without adding weight to the structure. Every turn becomes easier on steep slopes, and you conserve energy throughout the ascent. On the descent, the ski maintains sharp handling and excellent grip on hard snow or spring-like powder. It offers solid alpine performance far beyond what its weight would suggest.

The ski

For the days measured in vertical.

This is the ski of choice when the main focus is on ascents and long runs. It excels on long spring runs that demand a steady pace, as well as on icy morning trails where every gram saved helps conserve your energy. Its efficiency on the ascent is paired with stable, reassuring handling on transformed or hard-packed snow. For efficiently covering elevation gain, it’s the perfect choice.

Shaper's Note

Every gram earns its place.

We developed the Ubac 89 for skiers who prioritize vertical elevation gain as the focus of their outings. Our goal was to eliminate excess material from the core while maintaining the necessary stiffness at the edges and tip. Tested during long morning ascents in the Mont Blanc massif, we fine-tuned the weight reduction without ever compromising the ski’s performance on hard snow.

FRANCOIS K

Perfectly versatile

It does exactly what you ask of it—effective on any terrain, in any snow conditions. The ski delivers without being demanding. A great all-around option Touring !

LIONEL A

Great experience

Touring : A day of off-piste skiing with excellent, almost powder-like snow. A highly responsive ski with solid stability on descents and good float in powder. They’re lightweight to carry in a pack and easy to hike with. For finishing on the piste at the end of the day, they offer good grip on hard snow. A top choice for versatile skis.

SANDRINE G

Touring , have a great time skiing!

Lightweight skis (1.2 kg) that handle well in packed snow. Despite some vibration at the tip at higher speeds, the skis don't knock against the snow! They hold up relatively well on icy snow.

LORE C

Lightweight but easy to handle!

I'm not a very good skier, and I'm looking for a pair of Touring skis that aren't too heavy but aren't too light either, to help me on the descent. I've only skied on the groomed runs, but even there, the skis gave me quite a bit of stability!

Construction

Lightweight Construction:
One goal: to provide skiers with a lightweight, comfortable ski for all snow conditions. This is achieved through a combination of fiberglass and carbon fibers, making the skis in the Freerando line twice as torsionally stiff. The paulownia wood core saves a few extra grams without compromising the ski’s feel on the snow or its long-term durability, as a foam core might. The ABS sidewalls and high-strength steel edges ensure this ski can withstand the bumps and impacts it may encounter throughout the winter. A construction that allows freerando skiers to ski in complete safety!

Semi-Cap:
Our SEMI-CAP sandwich construction ensures optimal power transfer throughout the ski and provides the skier with all the grip needed on the hardest snow. The skis’ durability is also extended thanks to the ABS sidewalls (increased resistance to cold and impacts).

Rockers & Camber

Tip Rocker “25%”
Tail Rocker “15%”

Moderate camber

Shape

Multi-radius shape:
A ski design method that allows the radii to vary across several independent zones (front, middle, rear). This enables a very short radius underfoot (for increased maneuverability) while maintaining forgiving tips in difficult snow conditions.

Flex

Stiffness:
4/5

Torsional stiffness:
Its good torsional stiffness optimizes its grip on hard snow.

Who is the UBAC 89 designed for?


For the regular hiker, the experienced alpine skier transitioning to the “ Touring,” and the enthusiast of long-distance ski tours and backcountry skiing. This is the explorer of the lineup: the lightest, most responsive, and most precise in turns.

Which size of UBAC 89 should you choose?

The UBAC 89 is available in 155 and 162 cm for women, 169 cm for unisex, and 176 and 183 cm for men. For a classic Touring , choose your usual size or 5 cm smaller: this makes it easier to step out of your boots on the trail and provides better maneuverability on steep terrain.

What are the dimensions and radius of the UBAC 89?

The UBAC 89 has a base width of 89 mm. Dimensions range from 121 × 89 × 107 mm for the 155 cm model to 126 × 89 × 111 mm for the 183 cm model, with a turning radius ranging from 16 to 20 m. Detailed specifications by size are listed in the table on the product page.

How much does the UBAC 89 weigh?

The UBAC 89 weighs between 1,150 g for the 155 cm length and 1,400 g for the 183 cm length, per ski.

What is the profile of UBAC 89?

Medium camber, slight double rocker, stiff flex, medium turn radius.

Which " Bindings " should be installed on the UBAC 89?

The UBAC 89 is mounted using an insert- Binding : the FORGE[Tour] (DIN 4-10, 91, 97, or 102 mm brakes, 295 g) or the FORGE[Pro] (DIN 3-11), for example.

Is the installation of the Bindings s included with the UBAC 89?

Yes, assembly is included if you purchase Bindings at the same time as your skis and provide us with the necessary assembly information (boot shell length in mm / skier's weight / skier's skill level / skier's age).

Is the UBAC 89 stable on the descent despite its light weight?

Its stiff flex and medium camber grip hard snow without bending. It’s light enough for steep descents and sturdy enough to ensure the run down isn’t just a trip back to the parking lot.

Which skin for the UBAC 89?

An 89 mm ZAG base, available in Pro or Classic. Three lengths: S for size 155, M for sizes 162 and 169, L for sizes 176 and 183.

What is the difference between UBAC 89 and UBAC 95?

Six millimeters at the tip, for the same profile: medium camber, slight double rocker, stiff flex. Those 6 mm make all the difference in soft snow. The 89 excels at vertical and grip, while the 95 really shines in powder.
