The story of one of the most important inventions in ski touring history
I attached Alpine Trekkers to my downhill skis the first time I went ski touring and clicked in with my clunky Alpine boots. It was 1997, and I was probably lifting more than 10 pounds of gear with each stride. I was also young, fit and ignorant enough to think the system was amazing. Until one day a Swiss mountain guide using Dynafit touring bindings left me dragging a mile behind him.
I can still picture those bindings. They don’t look that different than the ones on my skis today or the first pin binding introduced in 1984, as such “Low-Tech” bindings are unique among outdoor gear.
Besides the two wheels, today’s mountain bikes share little with the early off-road rigs of 40 years ago. Backpacks have gone from exterior aluminum frames to internal suspension systems. And while skis still have a tip and tail, everything in between has changed.
Meanwhile, the pincer toe, U-pin and boxy heels of today’s tech bindings are obviously descendants of the binding Fritz Barthel invented four decades ago.
“Laziness is the mother of invention,” says Barthel.
The story goes, in 1982, he and a buddy were driving back to Austria from a Mediterranean climbing trip and, on a whim, decided to ski Mont Blanc. When they reached the summit, they were exhausted and nearly didn’t make it back to the car. On the drive home, Barthel, an engineering student and lifelong tinkerer, wondered what he could have done differently. Low Tech’s 30th Anniversary
“I could have trained more to be in a better shape,” he told GearJunkie, a website. “But this was not really an option for me, as I’m a very lazy person.” It All Started With a Near-Death Experience: The Toe-Pin Ski Binding Turns 40
The logical solution was to design a lighter touring binding system. Touring bindings at the time worked similarly to today’s “frame” bindings with resort-style bindings mounted on a plate, or frame, that swivelled from a point near the toe. Barthel realized the key to a lighter setup was the relatively new introduction of stiff plastic ski boots. It would eliminate the need for a heavy frame. The problem was the connection.
After many iterations, Barthel developed a system that used metal pins at the toe that coordinated with notches on a boot and a similar connection at the heel that spun out of the way for climbing.
“At the time, everything had to be called ‘high-tech’ to be successful,” Barthel says. “But, what should this lightweight, mechanically simple binding be called? Low Tech, of course.”
By 1984, Barthel had a working prototype and a patent for his Low-Tech system. He shopped the idea to all the big boot and binding manufacturers, but they were put off by the unusual-looking binding and the fact shoppers of the new bindings also required new boots.
“I still have all the rejection [letters] of all the companies,” Barthel said. “There was no official interest.”
Eventually, Dynafit permitted him to retrofit the binding connections into its boots, with the catch that Barthel had to buy them first. Dynafit.com
His dad, an avid backcountry skier, raised some money, and Barthel turned his basement into a workshop. At first, sales were slow. Then, some ski-mo racers saw the advantage, adopted the system and started winning races. Soon, Barthel was manually retrofitting 1,000 pairs of boots a year. It was unsustainable for a home-based business, and Low Tech was finally enticing enough for the more prominent companies.
In 1990, Dynafit licensed the patent, took over the boot and binding manufacturing and renamed the Tourlite Tech system. (Thirty-five years later, Barthel continues to consult with Dynafit about their bindings and boots.)
As the system gained popularity among the growing ski touring community, Dynafit became synonymous with “tech” bindings. Barthel’s original patent expired in 2006. Overnight, several ski brands introduced their versions.
One of the first was Vancouver-based G3 or Genuine Guide Gear. In the mid-2000s, an alpine touring binding fit well with its mix of avalanche safety gear and telemark bindings. Its first offering, the Onyx binding, sought to alleviate concerns that the tiny pins weren’t reliable or robust enough for hard downhill skiing. It looked beefier and had lateral release values, similar to the DIN settings on resort bindings. It has since been replaced by more minimalist models that the new owner of G3 will continue to sell. G3 is back online and ready for another lap; see G3 Bindings.
The Onyx was a precursor to the Marker Kingpin, which had a pin-style toe but an alpine binding-style heel. Salomon and its sister brand Atomic eventually adapted the idea further with the Shift binding. It uses a pin-style toenail for skinning and a traditional alpine attachment system for the descent, Marker Kingpin Bindings, 2025.
Low tech is now catching on in snowboarding. First, individual riders milled pin connections into their soft boots or created their own “franked systems” out of alpine touring gear. Today, there are several brands, such as Phantom Snow. Voile and Spark R&D, who design and manufacture tech-style boots and bindings specifically for split-boarding, see Cripple Creek Backcountry.
The dozens of tech-style bindings on the market mostly stick closer to Barthel’s original goal of making ski touring lighter and more user-friendly. The latest company to get into the pin binding game is Tyrolia with its new Almonte 12 PT. They look and function very similar to the originals but are lighter, safer, more reliable and easier to use. As such, Fritz Barthel is one of the key architects who made ski touring the approachable and accessible sport it is today. I thank him every time I skin past someone sweating uphill in a clunky frame binding or, worse, Alpine Trekkers.
