Plum KAIRN 12 Ski Bindings + 90 mm STOPPER

Plum KAIRN 12 + STOPPER 90 MM Ski Bindings: Performance on the Ascent, Control on the Descent

The Plum KAIRN 12 + STOPPER 90 MM ski bindings are designed for ski tourers seeking a precise balance between efficiency on the ascent and commitment on the descent. Weighing 355 g per foot and featuring a DIN setting of 4 to 10, they are designed to optimize your ascents while maintaining controlled release on steep slopes, during expeditions, freerando, or freeride. The construction features solid-machined 7075 aluminum and reinforced front inserts, providing a rigid and durable base designed to remain reliable over time. Capable of supporting skiers weighing 35 kg to 100 kg, these ski touring bindings are designed for technical use without unnecessary compromise, from the ascent trail to committed downhill runs.

Front toe piece: PIN TECH precision and efficient entry

The front toe piece of the Plum KAIRN 12 ski touring binding features a PIN TECH interface with reinforced front inserts for precise boot retention. This design aims to improve longitudinal and lateral stability during the ascent as well as during strong downhill pressure, particularly on steep terrain where ski control is essential. The low weight per foot (355 g with stopper) helps reduce fatigue with each step, while maintaining precise tip control when engaging in hard or rutted snow. In technical use, this toe piece serves as the binding’s central pivot, providing a stable anchor point throughout the outing.

Heel piece: power transfer and compensation for the descent

The heel piece of the Plum KAIRN 12 + STOPPER 90 MM ski bindings is designed around a 20 mm adjustment rail, allowing for precise positioning relative to the boot sole. This rail, combined with an integrated compensation system, accommodates ski flex to maintain consistent contact between the heel and inserts during heavy pressure. In practice, this results in better power transfer during heel-side turns, while limiting unwanted variations in preload that could interfere with release. This feature helps maintain a consistent skiing feel in freerando and freeride, whether on compressions or in wide turns.

Climbing wedges: three positions to adjust effort

When climbing, the Plum KAIRN 12 + STOPPER 90 MM rely on climbing wedges offering 3 positions, with two heights set at 50 mm and 65 mm. This trio of positions allows you to adapt heel support to the slope’s profile, whether you’re on a long flat section, a gradual ascent, or a steeper incline. The goal is to distribute muscle effort and reduce strain on the calves and Achilles tendons, helping you maintain muscle freshness all the way to the summit. Combined with the binding’s lightweight design (710 g per pair), these climbing cleats help make long ascents more consistent and manageable, even in expedition conditions or on steep routes.

Safety and release: DIN range from 4 to 10 for demanding use

The Plum KAIRN 12 + STOPPER 90 MM ski bindings feature front and lateral DIN settings from 4 to 10, allowing you to adjust release values based on your weight (between 35 and 100 kg), your skiing style, and the terrain you’re tackling. This range covers a wide spectrum of uses, from technical touring to more demanding freeriding, while maintaining precise control over the force required to release the boot. The integrated rear compensation system also helps stabilize release values when the ski is under heavy load, which is particularly important on steep slopes or in uneven snow. The goal is to provide a clear balance between foot support during strong pressure and release when forces exceed the selected setting.

Materials and Durability: Solid-machined 7075 aluminum

The Plum KAIRN 12 features a construction made from solid-machined 7075 aluminum, an alloy renowned for its strength-to-weight ratio and widely used in technical components. Machining from solid stock produces uniform parts with high precision in the fit of contact surfaces, contributing to the reliability of the toe and heel locks over the seasons. The reinforcement of the front inserts is designed to limit wear in the area most stressed during both ascents and descents. The binding is advertised as compatible with ski stoppers and leashes, allowing you to use the Plum KAIRN 12 + STOPPER 90 MM setup in various configurations depending on your terrain preferences and safety habits.

In summary, the Plum KAIRN 12 + STOPPER 90 MM ski bindings offer a well-rounded package for ski tourers who want a lightweight ski touring binding for ascents, with adjustable DIN settings and a design that remains precise and stable on descents. If you’re looking for a reinforced PIN TECH toe piece, a heel piece with compensation, and a setup suited for steep slopes, expeditions, freerando, and freeride, this model provides a solid foundation for your ski setup in the ski touring binding category.
