Backcountry Skiing Bindings
Virtual Museum (museum index)
|Through years of testing and product development, backcountry skiing bindings have progressed from simple cable bindings to engineered machines that represent state-of-art materials science and mechanicals. This collection of backcountry skiing bindings covers the full historical range of modern bindings.|
1993 Dynafit Tourlite
In 1990 The first production models of the Dynafit Tourlite Tech (TLT) began limited circulation in Europe. The binding became widely available around 1992/93 and was first brought to North America during that period.The unconventional and fragile looking Dynafit backcountry skiing binding was slow to catch on. While it did save an immense amount of weight over other brands, changing the vertical release setting required taking the heel unit apart and swapping a spring, and the vertical release tended to behave as if it was higher than the numbers printed on the springs indicated. Nonetheless, devoted ski alpinists quickly realized that the Dynafit saved so much weight it could markedly enhance their performance. More, the diminutive grabber was far from fragile. Vastly improved over the next decade but remaining true to the original design shown here, Dynafit is now the most popular alpine ski touring binding in the world.
History of the Dynafit (Low Tech) Binding
In the mid 1980s, rumors circulated of people who were experimenting with building binding parts into ski boots. The goal was to eliminate redundant parts, especially the plate that connected most randonnee binding's toe and heel units. Rumor held that people were building the spring bars from a Ramer backcountry skiing binding into a boot, so all you needed on the ski was a heel unit and the toe pivots from the Ramer (Ramer binding museum displays.)
As it were, a Tyrolean father son team (of Austrian nationality), both mechanical engineers, were inventing the TLT binding in their garage (the binding was then known as the "Low Tech".) Manfred Barthel, the father, supported his son Fritz who went through years of intense research and development to come up with a workable and durable unit they could sell to the public. For the first prototype constructed in 1982 they indeed used Ramer parts for mockup, and subsequently tested their designs in Europe and during trips to Canada. The Barthels, inspired as they were, took the concept of using the boot as the binding plate and refined it to an astonishing degree.
In the mid to late 1980s the Barthels made the binding themselves and retrofitted the boot fittings in a small factory in the basement of their family home. At that time they called the binding "Low Tech," which is still the name of Fritz Barthel's engineering consulting business. For boots the Barthels picked a Dynafit touring model that was lightweight and functional, and thus developed a relationship with the Dynafit boot company, who then purchased rights to brand, manufacture and sell the Barthel Low Tech binding (as well as selling boots with the fittings factory installed.) The binding was eventually named "Dynafit" once the Dynafit company began handling it.
The Dynafit company was founded in 1950 (bought by Kneissl in 1995 and now part of Salewa), and produced excellent alpine ski boots for years. In 1983 Dynafit introduced the classic red Tourlite randonnee AT ski boot. This boot was a fraction of the weight of other backcountry skiing boots, skied as well, was quite warm, and even doubled as a decent winter climbing boot (Colorado's Gary Neptune climbed Mount Everest in his). This was the boot the Barthels picked for installing their binding fittings, and the boot Dynafit later sold with the fittings factory installed.
The Dynafit brand was bought by Salewa in the 1990s and resurrected as a ski touring equipment company that included the Dynafit binding.
The Dynafit TLT binding was first brought to North America in 1993, and while not immediately popular was adopted by a few savvy ski mountaineers and gradually grew in favor with skiers worldwide. Manfred and Fritz Barthel deserve a huge amount of credit for bringing their binding to market, then refining it over the next decade. And let's not forget Paul Ramer, who's ball-and-socket binding concept was inverted and shrunk to create the pivot mechanism for the Dynafit.

These bindings were provided to Lou Dawson in 1993 by Lock Miller, owner of Marmot Mountain Works. Lock was the first North American retail importer of the Dynafit binding. Thanks Lock! First covered in Couloir Magazine V1-3 Feb/Mar 1994
