Understanding the splitboard

A splitboard is essentially a snowboard that can be split in two to form a set of touring skis. Once at the top, the snowboard is reconstituted to enable a traditional snowboarding descent. This system also requires special bindings and skins for ascent.

Choosing size and shape

The size of the splitboard is crucial and must correspond to your height, weight and riding style. In general, a rider will choose a splitboard that's a little longer than his park or piste snowboard, as this offers better flotation in the powder. Longer boards are also more stable at high speeds and on varied terrain, while shorter ones are maneuverable and practical for tight turns.

The shape of the board also influences how it performs in snow. Designs can vary from directional, optimized for downhill riding, to more symmetrical shapes, ideal for those who want a freestyle-like experience even in the backcountry. The presence of a rocker (curvature of the board) increases maneuverability and aids flotation in deep snow, while a camber (arc under the board) offers better grip on ice and a crisper response.

Materials and construction

A splitboard's materials determine both its weight and responsiveness. Lightweight wood cores such as paulownia are often preferred for their compromise between weight and performance. The addition of composite materials such as carbon or basalt can increase rigidity and durability while reducing overall weight.

The quality of construction directly influences the durability and performance of a splitboard. Techniques such as sandwich construction and composite topsheets are indicators of the quality and care taken in the manufacture of the board.

Accessories and Complementary Equipment

Splitboard Bindings

Splitboard bindings are specially designed to switch from ski to snowboard mode. They need to be both lightweight to facilitate climbing and robust to support descents. Some models offer adjustable binding angles and improved locking mechanisms for quick and safe conversion.

Seal skins

Splitboard sealskins are essential for snow climbing. They must be correctly sized for the width and length of each ski when the board is split. The adhesive must be reliable in all temperatures, and the pile must offer a good balance between grip and glide.

Hiking Boots and Poles

Opt for snowboard boots specially designed for touring, offering greater flexibility and support for long climbs. Adjustable trekking poles are also essential to aid ascent and stabilization when traversing steep slopes.

Selecting a Splitboard: Criteria and Recommendations

1. Type of terrain and expected conditions: Choose a board suited to the conditions typical of your region or the areas where you plan to ride most often.
2. Experience and riding style: Be honest about your skill level and what you want to do with your splitboard. This will influence the type of board and technical features you choose.
3. Budget and durability: Investing in a high-quality splitboard may represent a higher initial cost, but will often translate into a better experience and greater durability.

In conclusion, choosing a splitboard is an important decision that requires a thorough understanding of several technical parameters. Size, shape, materials, and complementary equipment all play a crucial role in the winter mountain experience. Take the time to consider your specific needs before making your purchase to ensure many seasons of backcountry fun.
